I am also not a fan of stable coins. I sometimes wonder why stable coins are created. Are they for trading? Their price remain stable and there is not any profit from trading. But I think they serve as a platform to exchange and store USD. I like tether stable coin.
Stable coins play as means to switch between bitcoin to altcoins; bitcoin to stable coins, then fiats; altcoins to stable coins then fiats. That's all. There is no reason, no benefits to invest in stable coins, because their price are stable. Do you want to invest in a coin that has stable price over time?
