Arduino Bitcoin Miner


Arduino Bitcoin Miner




Build and upload sketch in Arduino IDE. Arduino will work as a serial port Bitcoin miner (namely Icarus, device id ICA 0). Run BFGMiner from the command line using testnet-in-a-box address and an Arduino COM port, e.g. for COM5 that would be:

Or, for the mining pool (e.g.


Current hash speed is pretty abysmal, considering the 16 MHz Arduino Pro Micro (ATmega32U4 at 5v):

  • ~ 50 hashes a second for arduino-bitcoin-miner.ino
  • ~ 150 hashes a second for the AVR assembly version

At this rate you would need about an year to find a single share. For the commercial Cryptovia library (42744 cycles per 50 bytes) it would be roughly the same number of hashes (16MHz / 42744 / 2 ~ 187Hz), maybe even less. All given values are for double hashing the 80-byte block header, so every hash takes two 64-byte SHA256 blocks, consdering midstate optimization.

What if

According to Mining Profitability Calculator, mining $1 a day needs 1.5 TH/s, 1 BTC a year needs 42 TH/s (numbers may vary).

  • At 150 hashes a second per Arduino, mining one dollar a day would need 10 billion Arduinos
  • Pro Micro consumes 200 mA, mining $1 a day with a 10 billion Arduino rig will need 2 gigawatts of power (Great Scott!)
  • With an average price $0.2 per kWh, 2 gigawatt mining rig will cost you about $10M a day (minus one dollar you make)
  • If you prefer a single AVR chip, mining 1 Bitcoin on ATmega32U4 will theoretically take about 280 billion years


There is also a PC version of the serial port miner (see pc_version directory). You will need a serial port emulator, e.g. com0com. It creates COM port pairs, e.g. you listen on COM8 and specify COM9 for the BFGMiner. Emulator hash speed is currently about 1.14 million hashes a second (could be improved, maybe 6-7 million hashes per CPU core).


To debug solo mining on the localhost you'd need testnet-in-a-box. Get the setup here: There are two debug modes - testnet and regtest, edit configuration files and set testnet=1 or regtest=1 accordingly.

Testnet mode mining works with old bitcoin-core releases only. I use bitcoin-qt (coderrr mod with a coin control feature). Get it here:

Regtest (regression test mode) is a preferred method for debugging new bitcoin-core versions (I've used 0.16.0). You need to download or generate at least 1 block to enable mining or you get RPC error 500 "Bitcoin is downloading blocks". Either use "generate 1" in bitcoin-qt (Help - Debug Window - Console) or use a Python script to run commands via RPC:

Both testnet and regtest work well with cpuminer (and it supports fallback from getblocktemplate to getwork for old clients):

CGMiner 3.7.2 also supports testnet and getwork, use --gpu-platform 1 for laptop nvidia cards (1030 gives about 200 Mh/s):


This miner uses Icarus protocol via USB serial port emulation (there is no USB autodetection, you have to specify a COM port).


  • No detection is needed (no special command for this).
  • Wait for data. Each data packet is 64 bytes: 32 bytes midstate + 20 fill bytes (any value) + last 12 bytes of block header.
  • Send back the results, i.e. when valid share is found, send back the 4-byte result nonce immediately.

Read more about the protocol here:

BFGMiner specific

  • BFGMiner tests block with nonce 0x000187a2 first. Since we need to test only 100258 values the reply should be instant.
  • Sends work division payload 2e4c8f91(...). Expects 0x04c0fdb4, 0x82540e46, 0x417c0f36, 0x60c994d5 for 1, 2, 4, 8 cores.
  • If no data sent back in ~11.3 seconds (full cover time on 32bit range at 380MH/s FPGA), miner sends another work.

USB autodetection

Not implemented yet, you have to specify a COM port in the command line. Original Icarus uses either VID_067B & PID_2303 (USBDeviceShare) or VID_1FC9 & PID_0083 (LPC USB VCom Port driver). Default Arduino Leonardo driver uses VID_2341 & PID_8036, and neither BFGMiner nor CGMiner recognize it as an USB mining device. Changing hardware ID's requires updating bootloader and fixing the driver.



As the majority of Bitcoin miners, this one also uses midstate hashing optimization. Midstate is a 32-byte long data string, a part of the hashing function context after processing the first 64 bytes of the block header. Simply apply the state from the payload, process the remaining 16 (80-64) bytes of the block header (including nonce in the end), and hash the result.

// apply midstateSHA256_Init(&ctx); memcpy(&ctx.h, midstate, 32); ctx.Nl = 512; // set nonce and hash the remaining bytes *(uint32_t*)(block_tail+12) = htonl(nonce); SHA256_Update(&ctx, block_tail, 16); SHA256_Final(hash, &ctx); // hash the resultSHA256(hash, 32, hash);


Scrypt is not supported (yet). ATmega32U4 only has 2.5K RAM, so even basic Scrypt-based cryptocurrencies are not feasible, for example, Litecoin uses Scrypt with 128 KB RAM (in order to fit into a typical L2 cache). Other cryptocurrencies have even higher memory requirements, e.g. CryptoNight algorithm used in Monero requires at least a megabyte of internal memory.



Mining Cryptocurrency using Arduino (DuinoCoin) © GPL3+

cryptocurrencies have become more and more popular in the last few years, and the main reason for this is the increase in their value. However, this case should also be taken into account as the value of currency cryptocurrencies increases. The reason for the large number of users and other such factors is increasing. Meanwhile, there are currency codes that, in addition to low prices and lower extraction methods, have an interesting method for extracting or mining, for example DuinoCoin, which we will be able to mine these currency codes using microcontrollers. Visit CiferTechfor more tutorials, and be sure to follow my Instagrampage to support me.

DuinoCoin ᕲ

DuinoCoin is the only coin that can be mined with computers, Raspberry Pi, Arduinos, ESP boards and many other microcontrollers. Supported by a large number of operating systems. It also has a growing and friendly community and is easy to use and exchange. This password can be mined on various systems and also supports Python and C ++ programming languages. Dinoquin has special software wallets and miners released by its developers, this currency code has been in operation since 2019. Also, the transfer and receipt process in DUCO is very easy. In DinoCoin, we first select the desired cryptocurrency pair, for example DUCO to BYND, then fill in the exchange form (username, amount exchanged, etc.) then wait for the exchange. You will be notified of your assets by email.

  • Coin supply: 350 thousand
  • Algorithms: DUCO-S1, DUCO-S1A

Arduino board

The Arduino board suite is one of the most popular development boards among embedded engineers, available in various models including Micro, proMini, Nano, Uno, as well as Mega. The core of these popular boards is the AtMega328 series. Arduino is an open source hardware, software and software platform. As mentioned earlier, the Arduino platform includes an open source single-board microcontroller that forms part of the Arduino hardware. In addition, the Arduino platform includes Arduino IDE software designed for programming Arduino boards and a software bootloader that loads on the microcontroller.

Why use DUCO?

Simply put, there is literally no other currency password that supports it. Many people have an Arduino that is just waiting for days to get used to it. Using these small devices in the world of cryptography is an interesting idea. The DUCO team wanted to create something new, innovative and unique, and from the point of view of the community it has assembled, it seems to have made it possible to extract ultra-low-energy devices. DuinoCoin also supports the following boards.

Bitcoin miner - Is it possible?


That's the thing about cryptocurrencies - they are just as ephemeral as what we already use, so why can't we all just agree to use such a thing? It's the same "gentleman's agreement" that we already operate under, but it does have some upsides...

PeterH: A modern high performance graphics card has thousands of times better performance, memory and bandwidth available and even so will only earn cents per day.

For bitcoin - maybe (it seems like it is even less than that, honestly - which is why people have switched to ASIC miners); for other (newer) cryptocurrencies, you can actually make a fair amount per day from what I understand. I have a friend who has set up a small rig (30 or so GPUs) in his garage mining some of the alternate cryptocurrencies that are easier to mine; he's managed to make a few hundred dollars (if he is lucky, he may break even on his investment).

PeterH: The second way is to sell mining equipment. Just like a gold rush - the most reliable way to get rich is by selling shovels.

You definitely have that right; my friend is mainly in it to understand how all of this works - with maybe a minor hope that he hits on the "next bitcoin" (that is, the next cryptocurrency to have a bubble) - by mining for many different alternatives. In other words, maybe gold is played out for most mines, but maybe copper is easier to get and will become worth more. Divestment of efforts, resources, etc - in the hopes that maybe one or more hits just as big. I don't really see him getting lucky like that, but in the meantime he'll probably learn a lot in the end.

PeterH: For what it's worth, I don't see Bitcoins ever being accepted for general use in their current form because they are completely unaccountable - it's the electronic equivalent of leaving banknotes under the park bench and hoping that the person who takes them decides to send you the goods you were promised.

Well - then it's no different than any other payment system, then, is it? I mean, if you buy something from someone, then send cash in the mail, nothing says they'll send you your item. Or even if you pay with paypal, or a credit card, or a check.

That's what an escrow system is for (arguably, that's what Silk Road - and I think Mt Gox also provided - an escrow system, along with ratings - so that both buyer and seller were protected and that the exchange actually happened).

But yeah, if you transfer cryptomoney from your wallet to some other guy's wallet, there's nothing that says he'll send you what you were buying.

PeterH: Unless/until the transfer can be bound into a contract you would be mad to trust that as a payment system.

Again, what "contract" really exists with current electronic payment systems? People get ripped off all the time in the same kinds of manner - and sometimes there isn't even any way to show accountability. Arguably with cryptocurrency, you can at least show who made what payments when (there is a ledger for all wallet transfers), which isn't easily the case with other systems (certainly not cash - and even with credit/debit, individuals can't see all transactions that have occurred to/from accounts - not without court orders and such - so in effect, cryptocurrencies are more open - which would be a lot nicer if they were in broad use, because then we could easily see who is donating to whom in political campaigns and such).

PeterH: I believe it's technically possible using the same PPK mutual signing approaches proposed for secure exchange systems, but I don't see any sign of it happening yet.)

As I said - Silk Road was doing some kind of escrow-based system (where you had a wallet on the system, and transfers happened between wallets on the system itself once parties agreed - rather than the more direct personal-wallet-to-personal-wallet); I don't know if there were any PPK signings or whatnot happening, but I could see that being done.

CrossRoads: Bitcoin realm seems rife for ripoffs too. So many cases of bitcoin thefts in the news recently.

Much of this has happened because of insecure wallets - it would be like leaving your physical wallet out on a park bench or something; also, people have had their wallets stolen, but not their keys (so it would be like leaving a very secure safe out in the open public - someone could steal it, but they may never be able to open it). This is what happened mainly on the Silk Road takedown by the Feds - they got a ton of wallets (stored as files on the servers) that had a ton of money (in Bitcoin) in them, but that money is essentially lost to the market because no one (not even Feds - not yet, at least) can open them and use them (and if they did manage to crack them in some manner - the Bitcoin community would likely see it).

At least, that is how I am understanding things. I am sure that some people left behind wallet files and also the keys to them (like taping the combination to a safe) - people can be very stupid about things like this.

Lastly - if it isn't apparent from any of the above - I am no expert on this whole cryptocurrency thing, but a lot of people don't seem to understand it at all. Which isn't surprising - most people have no real concept of how baseless our entire monetary system (worldwide) as a whole is. For some reason, people think these bits and bytes flying through banking computer systems have some kind of intrinsic value, when in reality, the only value they have is the value we humans assign to it, for whatever arbitrary reason. Indeed, it has always been this way (even with barter, of course). So if everything is being done with a computer - why not an alternative system? If enough people give it value - then it has value. What governments don't like about cryptocurrencies, I believe, isn't that issue - it's more the fact that such currencies are more open (you can see all of the transactions - nothing is hidden from anyone), plus they don't require any middle-men (just like cash) - but are just as easy to use and transfer (because the internet and computers) as credit or debit systems, and they don't require banks, and of course - because of all of this - in theory taxes and/or other fees can be easily avoided.

Introduction: Build a Cryptocurrency Tracker With ESP8266 and Arduino


With the latest craze in the world of cryptocurrency and, as coin hodlers ourselves, we wanted to have a tiny desktop display cycling through the current prices of different coins.

Although we can certainly find the same information using apps and websites (for free!), we discovered that having a dedicated device on our desks displaying the data constantly minimized the time we spent on tracking it. Not to mention that building the device is a great excuse to work on a ESP8266-powered, internet-connected, DIY electronics project for any Maker out there! (bro/sis, do you even IoT?)


The main goal is to have a dedicated, inexpensive, device that would help us avoid repeatedly checking websites, apps, email, writing scripts, etc., in order to monitor the ups and downs of coin prices.

In terms of what's required, we challenged ourselves to use the minimum number of parts, and require no special tools/skills such as soldering.


To build a price tracker for cryptocurrency we simply needed two pieces of hardware: an internet-capable microcontroller to gather the data, and a screen to display it, we tried to find the best solution considering ease of use and cost.

OLED display

Given our main goal of having a device with a small form factor that could sit on our desks, the first choice was to use a 0.96" OLED screen to display the price data.

Not only are these displays small (and bright!), but they're very easy to control over i2c merely having to connect 4 wires to our microcontroller or single-board computer: 2 for power and ground, and 2 for the data and clock lines.

ESP8266 microcontroller (SoC)

What can we say about the ESP8266 that hasn't been said about the wheel, sliced bread, or the iPhone... we love it! It's the most convenient, inexpensive way to have a microcontroller running code while connected to a Wi-Fi network.

The SoC comes in a variety of modules, breakouts, and development boards. For this project, we evaluated a few options and settled DevKit 1.0 Development Board for its compactness and our familiarity with using an OLED display with it in past projectsOLED display with it in past projects!

Running on the microcontroller, we need software that's able to query the price data from dedicated servers, as well as to control the OLED screen to display the queried data.

Price data API

As of this writing, the best sites that provide a free API to query the current prices of different cryptocurrencies are:

Even better, at the moment they neither of them requires an API key, so we only need to write the firmware to perform queries and parse the result to obtain the necessary data.


To perform the two tasks mentioned above, namely, query/parse data and control the OLED screen, we use a piece of code running on the ESP8266.

The firmware performs 4 major tasks:

1. Connecting to the Internet

Using the built-in Arduino library for the ESP8266 and entering our WiFi network credentials (ssid/password) we connect to the internet.

2. Querying the data

Using the built-in Arduino library for the ESP8266 , we create a WebClient object that allows us to send a GET request to the servers' APIs and retrieve the price data.

3. Parsing the data

Using Benoît Blanchon's fantastic Arduino JSON library (available in the Library Manager), we can easily get the parts of the JSON-formatted data that interest us.

4. Displaying the data

Using a couple of OLED Arduino libraries, it's straight forward to display the price data on the screen as well as our custom graphics. Most of the work, however, goes into making the UI both intuitive and aesthetically pleasing.

Step 1: What Is the ESP8266?

Since the summer of 2014, the ESP8266 has seen a wide adoption as a cost-effective solution for IoT and WiFi-capable devices. The ESP8266 was developed by Shangai-based Espressif Systems, as a Serial (UART) to Wi-Fi SoC (System On a Chip) based around a Tensilica Xtensa LX3 DPU. This tiny IC includes an RF front end, RAM, and (usually) an onboard TCP/IP stack that allows it ready to connect to a nearby Access Point, to act as an Access Point itself, or both.

ESP8266 Development Board

The ESP8266 provides a cost-effective solution to the rapidly growing market of internet-connected projects and devices (i.e., the so-called Internet Of Things), thus it has become one of the most popular development platforms over the past years. In consequence, a dedicated community has formed around the platform (, which has been focused on improving its functionality.

From the different ESP-NN boards and modules, we began to experiment with the ESP-12E. The main reason is that this module was the one chosen by the developers of the NodeMCU project for their hardware DevKit 1.0 (see Firmware Options for details about NodeMCU).

Step 2: List of Materials

Step 3: Setting Up the ESP8266

We've written a detailed instructable with all the steps needed to get your ESP8266 configured and ready for programming using the Arduino IDE:

We also have a video guide available here:

Maker sure you follow the steps carefully, and that at the end of the setup you're able to select the correct board and port from the "Tools" menu option!

Step 4: Wiring the OLED Display

Wiring the two is straight-forward, keeping in mind that we need 2 4.7KΩ resistors to pull up the I2C lines. The I2C pins on the DevKit board are GPIO4 for SDA (labeled D2) and GPIO5 for SCL (labeled D1), this we wire them to the corresponding pins on the OLED screen PCB as shown in the diagram below:

Using the default I2C pins for the ESP8266 allows us to simply use the built-in Wire library for I2C communication. With everything wired up, it's time to test some code.

Step 5: Installing Additional Libraries

There are a few different ways to install a library in the Arduino IDE. For detailed, step-by-step instructions on all the different ways to do so please visit our tutorial. The simplest method is to use the built-in library manager in the Arduino IDE. It can be accessed via the menu option Sketch → Include Library → Manage Libraries…

In the search field enter:

  • "ACROBOTIC OLED" and install the resulting option.
  • "Arduino JSON" and install the resulting option.

That's all that's needed, we can now dive straight into the code.

Step 6: Code Walkthrough: Crypto Tracker

The very first thing we do is forget about the OLED screen and simply figure out how to get the data that we'll eventually display on it. We use the Serial Monitor for printing out the data, and worry about the OLED later.

To get the data we first try to find where is it freely available. A Google Search reveals 2 popular services we can use, CoinMarketCap and Coindesk. Looking through their APIs let us know that we can access the current price for different cryptocurrencies by sending a GET request to:

If we simply point our browser to either of the URLs we'll see the data that we're after. However, to do so with the ESP8266, we need to first connect to the internet, and then use a web client.

Although both services work great, we'll stick with Coindesk for this project.

1. Connecting to the internet

Using the built-in ESP8266WiFi.h library, we use the begin method of the WiFi object with a couple of character arrays as arguments, which contain the credential to the network.

const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); }

As is typical, we do this inside the setup() function. Also, we use a while() loop to monitor the state of the connection. The loop runs until the connection is successful, though this blindly assumes that the network is available–a way to make the code more robust would be to handle cases where the connection isn't successful.

2. Using a web client

Using the built-in ESP8266WiFi.h library, we create an instance of the WiFiClient class, set up the request we're going to send to the Coindesk server, and declare the buffer where we'll store the server's response.

We also construct the request we're going to send to the server, specifying a minimum set of header fields that are needed.

#define CD_API "/v1/bpi/currentprice.json" #define CD_URL "" WiFiClient client; static char respBuffer[4096]; const char request[] = "GET " CD_API " HTTP/1.1\r\n" "User-Agent: ESP8266/0.1\r\n" "Accept: */*\r\n" "Host: " CD_URL "\r\n" "Connection: close\r\n" "\r\n";

Next, we attempt to connect to the host site using the connect() method of the WiFiClient object. We do some basic error handling if the connection isn't successful, but once again we assume it will be successful.

Using the print() method of the WiFiClient object (not to be confused with its counterpart from the Serial class), we send the request. We then close and flush the connection, and we also wait an arbitrary-but-reasonable amount of time (1 second) for the server to respond.

Once the server responds, we use a while() loop to load the response into our character buffer. To do this, we use the read() method of the WiFiClient object.

if (!client.connect(CD_URL, 80)) {<br> Serial.println("Connection failed"); return; } client.print(request);<br>client.flush(); delay(1000);<br>uint16_t index = 0; while(client.connected())<br>{<br> if(client.available())<br> {<br> respBuffer[index++] =;<br> delay(1);<br> }<br>}

By the design of the API to which we send the request, we know that the response from the server will be formatted in JSON.

Parsing JSON-formatted data

Although we know that the data is formatted in JSON, is we print out the character buffer we notice that there's some extra characters in the server's response. For this reason we use the strchr() method to trim the buffer (creating a new one) all the way to the first opening curly brace '{' where we know, by inspection, that the JSON-formatted data begins.

char * json = strchr(respBuffer,'{'); DynamicJsonBuffer jBuffer; JsonObject& root = jBuffer.parseObject(json); Serial.println("JsonObject: "); root.prettyPrintTo(Serial); Serial.println(); JsonObject& bpi = root["bpi"]; JsonObject& usd = bpi["USD"]; String tmp = usd["rate_float"]; data = tmp; Serial.print("BTC/USD:");<br>Serial.println(data);

Using the fantastic ArduinoJsonlibrary we can now parse the data. We can do so by creating either a Static or Dynamic JsonBuffer object (we chose the later), and calling its respective parseData() method. The JsonBuffer object(s) then allow us to pick the data we want by using the familiar keyed array notation.

For now, we can visualize the data in the Serial Monitor using the print() method of the Serial object (remember to initialize it in the setup() function!). But, the next step is to send it over to the OLED screen.

Displaying the data

Although several libraries exist (including our own!) for working with OLED screens, we chose to follow our quick-n-dirty standalone OLED demo:

As such, we created a helper file util.h containing a few constants including the font data. Please note that the file should be located in the same folder as the .ino sketch.

Then, it was a matter of creating a few low-level helper functions for setting up the OLED screen, and communicating with it. And one high-level function to print the data we wanted:

setTextXY(0,0); // Set cursor 0th page (row), 0th column displayString("BTC/USD:"); void printData(String data) { setTextXY(2,0); displayString("setTextXY(0,0); // Set cursor 0th page (row), 0th column displayString("BTC/USD:"); void printData(String data) { setTextXY(2,0); displayString("$");
setTextXY(2,1); char __data[sizeof(data)]; data.toCharArray(__data, sizeof(__data)); displayString(__data); } quot;);<br> setTextXY(2,1); char __data[sizeof(data)]; data.toCharArray(__data, sizeof(__data)); displayString(__data); }

We also encapsulated the data capture and parsing inside a getData() function, and the data displaying on the OLED screen inside the prinData() function. These two functions are called from within the standard loop() function every 10 seconds.

The prototype's firmware files are available at:

Introduction: How to Mine Crypto With Your Arduinos and Other Microcontrollers

Do you have an interest in the crypto world but don't know how to get started? Or maybe you know a lot about it but don't want to put in a big investment to enter it. Most cryptocurrencies require big and expensive miners to mine their coins. Duino-coin is one of the only cryptocurrencies that can be mined with an Arduino. Here is how to set up your Arduino to mine, Although don't expect to become a millionaire overnight.


-PC to program the Arduino and to store your Duino-coin

- A Board you can use to mine: Arduino, ESP8266, ESP32, Rasberry Pi

Step 1: Download the Latest Release and Unzip It

Download the latest release of Duino-coin files

(I do not take credit for any of the programs and files)

Step 2: Install the Duino-coin Wallet

You need somewhere to store all those coins you're going to be mining, so you will need a wallet. You can either install the Duino coin wallet from the ZIP or just use this website. Create an account and your wallet is all setup. You can use the software wallet by just opening or running it. If windows defender blocks it just hit "more information" and "run anyway". Then log into the software wallet. Your username that you chose is the username that you picked is will be used to mine and receive duino-coins, so choose a good one!

Step 3: How to Mine With Arduino Avr Boards

Arduinos need to be plugged into your pc to work because they do not have any wifi capabilities. To mine with an Arduino, find the file titled Arduino_Code and open it. Open the Arduino file and edit the specifications in tools to meet your board's specifications. Then upload the program to your board. After the program is done downloading, open the file titled AVR_Miner. Enter your wallet username and the port your board is on and you should be ready to go. You can run multiple Arduino boards at once if you want to.

Step 4: How to Mine With ESP8266 Boards

Since esp8266 boards have wifi capabilities, they can mine from anywhere that is connected to wifi. To mine with an esp8266 board, open the folder titled ESP8266_code and open the Arduino file. Edit the wifi name and password to your own. Also, edit the wallet username to your own. Change the specifications in tools to meet your board's specifications. Upload the code and your esp8266 and it will be all set up. You can check the serial monitor to see if it is working. You can unplug your esp8266 board from your pc and plug it in somewhere else. I've found esp8266 boards to be the most stable but not the most efficient.

Step 5: How to Mine With ESP32 Boards

Open the folder that matches your esp32 board (either single core or multicore). Open the Arduino file and edit the specifications in tools to meet your board's specifications. Edit the wifi name and password to your own. Also, edit the wallet username to your own. Upload the code to the esp32 and you should be all set.

Step 6: How to Mine With Raspberry Pi

Open the GitHub file on your Rasberry Pi and do the same as you did on your pc. Find the file named and move it to downloads, then enter the following commands on your raspberry pi terminal one at a time:

cd Downloads


Then enter your wallet information and it will start mining. It should remember you every time you use it.

Step 7: How to Mine With Your PC

You can mine with your pc in two ways: You can use this web miner, just enter your wallet username, and hit go. It will mine as long as the tab is open. You can also use the software miner. Find the file titled pc miner and open it. Enter your wallet information and it will start mining.

Step 8: How to Use Your Duino-coins

You can't buy anything with your Duino-coins because they aren't popular enough yet. But can send Duino coins to other people using the "Send Funds" section on the web wallet. Just enter the recipient's username and the amount you want to send. If you want to turn your Duino-coins into a usable currency you can exchange your Duino-coins into other cryptocurrencies by using this website.

Step 9: Resources
