Bitcoin will obviously stay, but there are close to 2.9 billion Tether tokens in circulation; if that exits the market entirely, we're going to take a massive plunge, and I am quite certain that if it was to happen today, sub $3000 is what we will be looking at.
The thing however is that people don't seem to care anymore about Tether. People as stupid as they are will keep using it because of the utility it offers. I have seen even influential people on social media admit that Tether is very likely a scam for the most part, but it offers a good hedge, therefore they will use it.
The situation as it is right now = we finally have the evidence we need to know that Tether is a fractional reserve financial institution.
Never in a thousand years will I ever sell one single satoshi for USDT. Fuck that.
