Interesting picks! We have quite some overlap. Personally I am not so sure about Potcoin since their Github is not updated for the last 2 years..https://github.com/potcoin/Potcoin/commits/master
Btw, do you use a specific approach when it comes to the relative weights of the coins you have in your portfolio? Maybe you can let me know what you think about my approach. Would appreciate it :-)
