This must be the reason why
US lawmakers seek to make stablecoins illegal without federal approvalThe US congress is about to create a law about this issue in order to control the the creation of stablecoins, they could have prevented some if they were just actively watching the crypto industry or they were just trying to let facebook do it and now they are to stop competition before everybody else does.
That will be applied on US territory and if you are not coming from US or US citizen and then that's not a big problem for you to use the stable coin. It looks like the majority of stable coins will be banning US customer from their service.
I guess the exchange site will not also let the US citizens to use stable coins too. It will be giving a big impact to the US citizens.
