I have researched crypto not just bitcoin and written a bit too. I think blockchain is good technology and sectors do benefit from the patent/privacy first approach. Speaking about cryptocurrency, since it can not be corrupted, an ecosystem for it does make sense. Legalised as an asset class, it is profitable. Like fkng everything chose your own risks and investments. Following ponzi schemes and then come question honest businesses is your own business sense. Be responsible on your own. Not everyone is polite to intentional nuisance.
