2017 was also the year that the very institutions Bitcoin originally sought to dismantle have begun to co-opt it for profit
So in other words, they decided to-- instead of destroy it-- began to simply buy it like everybody else on a level playing field, which encourages them to lobby in favor of it instead of against it; meanwhile bitcoin maintains its decentralized and open nature. Sounds like great news to me.
If people want to stupidly throw their money away buying shicoins like it's a casino, that's their business. I'd rather the feds issue PSAs instead of regulate the actual innovative coins to death, but we all know that won't happen.
