There might be a lot of stable coins in the market but that doesn't really mean they are unnecessary. Trading comes in pairs and the other half are stable coins. It is used to reduce the down fall whenever the market goes red. Libra coin might be a good one.
Another libra coin advertising huh?lol how can this be good as stable coin but centralized?no I dont think Libra is a good investment to limit the downfall because this kind of currency can be easily manipulated so better keep off this one.i rather choose ripple rather than this
