When the price of tokens you hold goes down it doesn't necessarily means losses for you. Real losses happen when you don't have those tokens anymore. To prevent your portfolio from falling low you need to hold several different coins.
yes at least a little better to lose the token price than to lose the token because we can save it until the price rises again, but still a big loss with what we sacrifice to collect tokens by spending a lot of time and capital. what I will do to avoid this is that I will be more efficient in holding quality coins and will take more time to sell, don't keep it too long because the market is difficult to predict.
