Obviously I think there are some people who should convert to stablecoins because they know that stablecoins are pegged to fiat, fiat will also be devalued, but fiat is preferred for this period as the market starts to gradually decline thus completely eliminating the risk. Either holding Bitcoin or stablecoin is the most appropriate choice, but it totally depends on what your game plan is, if holding bitcoin, stablecoin, that's better.
In a situation where the cryptocurrency market is volatile, the best solution is to keep your money in stablecoins. However, no one knows when prices will start to rise. If the Bitcoin price starts to rise now, altcoins are the best investment because they are the most undervalued.
It all depends on who likes what risks. If someone believes that altcoins are the future, in my opinion, he should invest in altcoins, because in a year he will be drinking champagne on an exotic beach. This is what investing in cryptocurrencies is all about.
