To date, the economic situation in many countries is in critical condition. Can the next financial and economic crisis be a transition to global use of crypto currency in international settlements?
I am not sure I understand what you mean. Are you saying that crytos will be the global crisis, or is it that they will help to overcome it? If people keep trading cryptos for the sake of trading and only focus on quick profits, the prices will get more and more manipulated by some half-fake news and this might indeed form the bubbles and eventually lead to their explosions. But the bearish market of our times is helping to circle out this option, because people get to realize which prices they truly believe in. If the market doesn't skyrocket, crisis cannot occur. And deflation cryptos can surely save the world when dollar finally collapses.
