There so much drama around the USDT I think the subpoena is a good thing one way or another. They need to get the question of being being legit or a scam out of the way so we can all move on. Best case would be they prove they are really backed by the US dollar and everyone can be happy but even if its not we can finally stop the FUD and people can stop moving so much money around messing with the market.
