Holding will be the perfect decision for times like now that the market is very uncertain. The price of Bitcoin has been moving up for sometimes yet people are still calling for the dip as they believe we haven't bottom out in all the dips that have happened in the market. People believe this dips were as a result of the different unfortunate events that unfold on the market like Luna collapse and SBF fraudulent acts.
Only Bitcoin and very few altcoins are moving in price and they are the only choices to go to if you want to trade in this season as you can buy Bitcoin and sell while making lots of profits from the price difference with in the day. As for trading alts, that would be a no since nobody can be sure of which one is surviving and not getting dragged down.
If you buy altcoins for short-term trading, then these are often very profitable transactions, you just need to understand which token to buy, if you do it at random, then it is clear that this can lead to loss of money. For a long-term hold, it is worth buying bitcoin and possibly a few altcoins that you are confident in, but you need to understand that this will not be so safe and therefore these investments should be small relative to your portfolio.
