I was looking at some of the top 50 stablecoins ,and im thinking Polkadot.
When you say stable coins, they're not volatile as you think. And there's no sense to think of it as an investment if you're describing the stable coins.
DOT I think is a good investment so if you're a holder of it and hopes for a big amount that shall happen on it in the future, then you just have to hold it.
Apart from erc and bep tokens
There's also trc20.
