You need to allocate your portfolio to different asset classes, ranging from stablecoins to classic assets that have proven themselves in the market for a long time, such as BTC or ETH. Stablecoins are sure to be useful for redeeming suddenly cheaper projects you're following, or those projects you already have in your portfolio. Don't forget about young projects. They too should be added to your portfolio for diversification, because young projects grow faster than older projects.
