stablecoins are really useful in this market that is always volatile, you can keep your assets safe at stablecoins, useful in buying and selling very large because their value is not lost, and traders need stablecoin.
Yes. We do need stable coins. The crypto market is crazily volatile and as such, stable coins are needed to protect investment when there's a fall on the exchanges. When investors dump and you're uninformed, you'll end up with loses.
I believe they are a response to bitcoins volatility and it's this easy to exchange to usdt or BUSD depending on which exchange byou trade with. However, the stable coins are becoming much and you're almost undecided on which to have. It's major advantage is that you get the dollar value no matter drop or dump.
