The truth is that the anticipation for crypto to go mainstream increases as time goes on. In fact there are skeptis who would have nothing to do with crypto unless it goes mainstream. Is 2018 that year when blockchain crypto goes mainstream?
It's probably because the price gain from bitcoin last year that's why many project start to adopt blockchain to make it more innovation, blockchain solves many problems in transaction, transparently, etc. that many technology cant solve that. No wonder if blockchain became mainstream now
