Compiling CPUminer for beaglebone black in 2019

First off, you’re not going to get rich from mining on your old unused BeagleBone black and you’ll arguably only lose money, but for about 10W of power, you might be able to mine some low difficulty altcoins that are cpu or gpu only. I am currently mining Galactrum on mine using CPUminer-multi.

Beaglebone black mining

Thanks to its wide array of miners, you can use cpuminer-multi to mine a lot of altcoins, so lets get into compiling it.

First, the deps

$ sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++ git

 

Now lets make a folder for it

 

mkdir cpuminer

cd cpuminer

 

Now we need the source code

 

git clone https://github.com/tpruvot/cpuminer-multi

cd cpuminer-multi

 

Now lets get to the compiling

 

./autogen.sh && build.sh

 

Yep, really that easy.

 

The usage for cpuminer-multi is below. Have fun mining! and Since cryptopia has been hacked, If you need a new exchange to trade on, check out my four favorite exchanges here

./cpuminer -u user -p pass -a algorithm -o stratum+tcp://pool:1234 -t cputhreads

Mining on the Raspberry Pi in 2019

Its 2019 and your Raspberry Pi is sitting in the corner. You haven’t used it much since your last project and you are ready to do more with it. Why not mine a CPU only or low difficulty coin? Sure you won’t get rich, but you’ll have some crypto to trade around and learn about compiling miners and how to use exchanges and how to use mining pools. The Pi also uses a very small amount of power.

 

Allow me to introduce to MagiCoin at https://www.m-core.org/

 

Magi coin uses a POW/POS system but with a bit of a twist. As they put it “MAGI concentrates on global energy savings when maintaining its blockchain system. MAGI aims at worldwide mining based on, for example, mobile devices. MAGI’s PoW with difficulty dependent mining rewards applies a limit to the total network hashrate, where huge amount of computational power for mining is no longer necessary”

This makes it the perfect target for mining with that old Raspberry Pi you just have lying around.

Click here to watch the YouTube tutorial

To get started install Ubuntu or Debian or Raspbian on your Raspberry Pi 2 or 3 and connect to it via ssh.

To begin make sure you have the latest software

sudo apt-get update

sudo apt-get upgrade

 

Next we need some deps to complete the compile of the Magicoin Miner

sudo apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++ git libgmp-dev screen

 

Lets make a directory so we know where the miner is to be located

mkdir magiminer

cd magiminer

 

Then clone the Github Repo

 

git clone https://github.com/magi-project/m-cpuminer-v2.git

 

Now we just need to compile the miner to get to hashing.

 

cd m-cpuminer-v2

 

./autogen.sh && ./configure CFLAGS="-O3" CXXFLAGS="-O3" && make

 

Now that you’re mining away, check out this cooling fan  kit we sell to help keep those temps down. Get 5% off with code “hashrate”

This might take a while but when it is done you’ll be ready to earn some Magicoin.

The next step is to find a pool, personally I use https://pom.m-hash.com/ They have a limit of 250K/hs so its great for slow miners

The next step is to start a screen session so that even after we disconnect from SSH the Pi continues mining.

 

screen

 

Now its time to hash away! To start mining

 

./m-minerd -o POOL_URL:PORT -u USERNAME.WORKER -p PASSWORD

 

To detach from the screen session after verifying its mining, hit ctr+a d

To reconnect, use screen -r

 

Magi is also POS so if you set up the official wallet you can begin staking coins, if you mine enough, or buy a few extra. If you just want to sell or buy Magicoin you can do that here.

Can you still make money trading altcoins in 2019

Can you still make money trading altcoins in 2019?

The short answer to this question is of course you can, but I know that’s not the answer you’re looking for. With coins like Tron, Ripple, Ethereum and Litecoin gaining mainstream appeal after the Bitcoin crash, many have made a fortune on trading altcoins. The hard part is knowing when to buy and when to sell. Another thing to consider is that certain exchanges may have different prices for certain coins. Just because one exchange is trading Ripple at $1 USD doesn’t mean that every exchange is trading Ripple at that price. So now not only do you need to try and guess market trends for these altcoins but now you have to keep track of all these different exchanges too?

Okay, that is a lot but its a still do-able. Now you need to select an altcoin. Sure, you can go with the already big names like ripple or etherum or zcash or monero but those already have some mainstream appeal. To really make it big you need to have the skill to find the coins that do not have that mainstream appeal and are still trading low so you can cash out when when they pick up that mainstream appeal. But what if you pick the wrong coin and it all comes crashing down? That’s where the exchange watching can help you. If one exchange is falling fast, it isn’t likely that the others have caught on to the recent downtrend yet leaving you a chance to get out before its too late.

Are there any tools that can do this for me? Absolutely there are, but are you sure you want to trust a bot with your money? Let me introduce Simple Crypto Compare. They offer a tool to help you keep track of all those different exchange price changes to give you the upper hand in crypto trading. Check it out here and let me know your thoughts on it the comments below.

Don’t want the tool and just want to get started trading altcoins yourself?

Great! Check out my list of my 4 favorite exchanges since cryptopia has been shutdown by clicking here.
