Mining can be complicated but it can also be simple.
Hadron is solving two problems at once - solving a need for complex image processing with the ability to mine free ER20 tokens by solving pieces of each problem in a browser window.
The project is currently in closed alpha with additional phases likely to roll out soon.
Currently, using just a browser tab each on two very old pcs I'm averaging about 60 tokens a day.
You might want to sign up and reserve your place for future implementations of mining.
Getting free ER20 tokens prior to exchange listing from a company with actual existing products and services is hard to beat.
