Code looks excellent compared to what?

OP, you might do well mining some of these shitcoins and then selling them for bitcoin, but I don't think any of them should be held for long.  And by that I mean longer than a month.  After that, it's like one of these hot tech stock IPOs.  People start dumping them onto the market, and the price tanks.  So as long as you keep that perspective you ought to do fine.
