Something tells me that if indeed cryptocurrency sticks around it’s going to sprout rules and regulations that are a mix of banking and securities regulations, and that will suck most of the “fun” out of it. We pause the stock market on a 5% drop and stoop it on 10%. Moving that much crypto in a day is probably never on purpose. Though in a distributed consensus system I don’t know how you’d enforce such a thing.
Anyone who knows anything about human systems knows that that's the end point: We'll be right back to banking as it is today, except with less efficiency and a ton of wasted time and technology that could have been spent making the current systems better.
