I don't keep USDT or stable coin, this is because I don't get to benefit from volatility profit. One of the biggest financial benefit of Cryptocurrency is the volatility. It makes trading sweet and sour depending on your level of expertise.
I am however not a fan of USDT, I am however interested in the rise of stable cryptocurrencies that are backed by real estate or some traditional commodity other than the dollar.
It's rarely to see that and as far as i know there was a lot if altcoins have declared such idea but they were failed to make it becomes a real thing. There are some altcoins backed by the gold and silver too.
