USDT was famous cryptocurrency but I was banned in Europe because they thought that is damaging their economy and it could be because USA is dominant on all the World and they have hold of USDT and they are effecting the economy of other countries because many cryptocurrency Investors buy USDT for the exchange purpose . USDC is also famous in the market and it will take position of USDC in the Europe but it is less famous in the USA but we are familiar with the both USDT and USDC. Europe thought that Trump is planning big ,So they want to cover their money .But it is harmful for the investors but they lost money by the decision of government. They produce fear in the market and USDT investors could be less .
USDT had enough time to change the rules to comply with European Mica regulations but they refused to comply, not that they were banned outright. Furthermore, they can return to the European market at any time if they want as long as they amend the regulations and comply with Mica.
USDC is issued by Circle and Coinabse, and there is news that Blackrock is also involved and all are US companies. So if we had to predict which stablecoin will be widely supported and used by the US in the future, it would be USDC and not USDT.
