I think one of the options that possible beginners can do. The only "stable option" in the Crypto space is probably stable. However it is not a good idea to convert your Cryptocurrency or token to stablecoin and leave it in a centralized exchange. Convert and send to the address that you fully control.
I just thought and I'm also a beginner it would be nice if you try that option because trying it doesn't hurt ...
That option is good, but depends on how often you trade, you have to consider the cost of having to send your money across exchanges because of the fees that they charge, even binance that has the lowest fee will cost you a lot if you do that like 5 times in a day, and this is one of the reason why many keep their trade balance into stable coin because of fees and because of the volatility of the market.
Stable coin is meant to keep the status of your coin in value active while if you keep your trade money into the wallet back could make volatility affect it when the price declines, just like bitcoin price decline now, it would never affect the ones that has been transferred to stable coin because the dollar equivalent will still be retain an I think that is why stable coins are very important to us.
