in my opinion holding long-term coins is also not necessarily able to profit. I think right now short term trading is suitable even though profits depend on our capital and at what price goes up
It depends on the market condition, if we have seen that the market behavior at the moment is uncertain, unpredictable, it is unlikely to do day trading, so the best thing to do is to calm at the moment and just convert fund to stable coin first, but if we are holding for long term, still for me it is good way to convert our fund first, so it won't hurt that much, it is better than panicking seeing the price is declining.
Short term or ling term trading depend which one market condition after I make investing with bitcoin and altcoin, if market support with short term trading I will sell my altcoin and if need for waiting long term I keep hold my assets after raise with higher price later, but many people like for investing with bitcoin and altcoin in long term period.
