But you are never going to make money that way, if you want to do that then just keep your fiat and be happy with it, if you are going to invest in this market then you need to select between bitcoin or some altcoins, if you are going to choose to invest in stable coins only do that when you are completely sure the price of all the market is going down as it did in 2018, that is the only moment in which you are justified to invest in those coins.
