Crypto Projects that Might not Suck

This document originated with an informal survey of Twitter and several mailing lists asking for nominations for crypto projects that "didn't suck". Over 100 nominations were received and culled down to this list. Projects marked with an "" symbol are relatively new and considered experimental. Apologies to project creators who are omitted. Corrections are welcome via pull request.
