blockchain is here to stay, there is no denying that. the technology has been ahead of its time and the world is now coming to terms with it. it cannot be stopped. we have seen much less advanced technologies last alot longer this is just the beginning. blockchain will impact lives of millions ( maybe billions ) on the planet so i dont see blockchain going away anytime soon. Cryptocurrency however is another story it will face challenges but eventually it should also be fine. just my thoughts.
