Mind you that hodling stable coins is not investing, your money doesn't accrue any return. The issuing corporation just pegs your money to a fiat currency or to another cryptocurrency, and it can be depegged at anytime or the issuing corporation can become insolvent and thus your stable coin becomes useless.

I'd definitely save my money in the bank than in a stable coin, a bank has more security and insurance of funds, meaning that if the bank collapses, you will get at least a certain amount of your money back; all of these doesn't exist in stable coins and it is even easier for a stable coin to fail than for a bank.
