Tether fud has make people invest in bitcoin and leave the USDT. This is the reason we see a mini bull run in bitcoin at the moment. There is no stable currency as Tether has been backed by USD by 74% only which is creating panic amount the USDT holders. Once this fud will be over people will convert back to USDT to book profit from BTC.
Thanks for stressing this out. The bull run we saw over the weekend was mainly due to Tether sell-offs and not because of fresh money entering the market. So in my opinion we may see a sharp decline in BTCs price once again over the next few days.
