I have two problems with all existing crypto currencies. 1. Are they fundamentally safe or are the scams? 2. Will they get shut down by governments? Both of those questions leave me feeling very open to risk. People willing to assume that risk before either issue has been resolved may reap whatever reward early adoption gives them. But if you build a business on the wrong tech you could get bankrupt or worse. Most of the big dotcom 1.0 companies disappeared (or are dying before our eyes, RIP Yahoo). Maybe it is better to be a crypto 2.0 business.
