I've registered, I think it will do great long term but there are some things I do not know how to feel about. The sale is just for 10% of the tokens, making that $75 mil cap meaningless in a way. The effective inflation for the first year is pretty damn large. Anyway, I will chuck some small amounts into it and see what happens, I will probably keep at least part of them for a few years I hope.
