Good post! Substratum Beta testing (Sub node, Sub Host, Cryptopay) is currently in progress and once the software is live for public use it should be a great and easy way to earn Substrate using your system (Laptop, PC etc). Substratum is going to be one of the best crypto projects of 2018.

Please check out my post on Substratum.
