What role would you give to cryptocurrencies right now? I don't see a massive adoptsion yet or why we should all stop paying sharply in dollars and start using stabiles like USDT. One of the most interesting articles I read on the subject on a little-known blog was https://theleadbtc.org/role-of-cryptocurrencies-in-a-cashless-society/. The ideas voiced there could really be a trigger for many people not to use cryptocurrency as much as cryptocurrency developers themselves probably want to.
