whether you are quickly influenced by news, or quickly go into shock when there is less favorable news for your crypto assets, it means you are a panic seller, if you like to follow the crypto trend, it's a good idea to choose a crypto coin that has a current market share, try to find it trend on coinmarketcap, take the token that is in the top 10 positions, if you are still in doubt, try to make friends with USDT or BUSD, and UST, you will not be affected by scary news for your assets, you will be safe from large losses.
For such people it is a better decision to not trade. Because trading needs a calm mindset not affected by things going around them, but capitalizing on movements either bull or bear, such people will always be on the losing side of things.
Stablecoins will only help if you know what you are doing. Newbies will not be able to handle them or have the proper intuition to know when to mediate through a stablecoin or have the patience to hold the stablecoin for long.
News makes the market move and that is what should be bought/sold. Holding shitcoins will never help but bitcoin should be the target. For those who are panic selling, start dummy trading and step aside from real life trading for sometime, to observe your mistakes.
