If and when cryptocurrency and/or bitcoin becomes the official currency of the world, do you think there will be a downside to it? If so, what do you think the negative effect will be once cryptocurrency becomes a worldwide currency?
At the moment the biggest downside of the cryptocurrencies is the way they are stored, you only need a little distraction or a wrong click and you can lose part of your funds or all your funds. For example with a bank trasferimento you need both the IBAN or routing number and the name of the person/company, so you should be wrong twice, with the public addresses well, I understand it's just a copy-paste but you never know...
