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?
if you talk about the negative side that will be gained if bitcoin becomes the world currency option, in my opinion, bitcoin as a decentralized currency will be one of the transactions that can be done freely without centrality related to the existence of the law that applies to the existing transaction system. So my point is what is feared that a decentralized system can be used by people who aim to commit crime.
