I think, with current market conditions holding is the best choice and is the safest way because it will reduce the risk of loss and will make you still have the opportunity to be able to get profit when prices start to rise
It is the best or the worst when we are just standing still and under attack of the market, I do not understand why you still choose this method to survive in trading, it is not effective, as long as you are still holding altcoin or bitcoin, your money will still disappear during the hold. Instead of trying to stick to that choice, you can look for another path to better survival, become a day traders and short term, with the current market fluctuations, it is not too hard for you or many others
