Once I went to the center of Saint-Petersburg, Russia for a drink. And you know what I heard? One guy asked me if I want to buy some cocaine for btc

Well of course I refused, but that was surprising and I think it shows that bitcoin IS the global currency now

Even Jeffrey Vernik says people should invest in bitcoin now 'cause it brings some profit in 5 years. I'm not sure it is a perfect time to buy but it's definitely not the time to sell. Anyway btc can be used as a non-national global currency NOW. Welcome to 2k18.
