I just wondered. Most people that got into bitcoin the last couple of weeks just did it because of the hype and the opportunity to make some quick cash. But lurking this subreddit I've seen loads of people actually believing cryptos are the currency of the future. So my question to you guys is why would extreme unstable currencies take over from fiat money? I don't believe the argument ""it's not controlled by the banks"", because it's controlled by some shady sites that ask fees to make transactions. Banks are at least controlled by organisations with authority that can punish unfair practices.
