You’ve got a computer, it’s running Linux and you want to try mining some Monero. Before you commit to running the system at 100% for a few weeks to see if you can make any money you should run a quick evaluation and see how much Monero the system can mine. Minergate provides a mining client that gives you a simple readout of how many hashes-per-second your system can crunch whilst it is mining and use that to work out your profit.
