I was looking at some of the top 50 stablecoins ,and im thinking Polkadot. Apart from erc and bep tokens
What do you mean top 50 stablecoins? If I'm not mistaken there are only limited stable coins on the crypto market right now, most popular is USDT and USDC, Polkadot is not a stable coin its a coin. Maybe you are confuse about a coin and a stable coin its different. To answer your question about Polka, I can say yes, In my own opinion its a good pick for long term holding.
True but I think he mean is stable coin in terms of price volatility is not that high compared to other shitcoins out there. Yeah Polakadot is good since its a Blockchain project that has a strong community but if your goal is to achieve more profit but less risk, You should choose more new rising star blockchain project like TLOS, KardiaChain and Flux
