How did you end up in 60% loss if you are monitoring the market often? If you are holding some legit and worthy altcoins then you don't have to panic this is normal in crypto but if you are holding a shitcoin then sell of all them right now before its value goes to zero. If you want to hold for a long term just always make sure you buy alts which has reputable developers and strong fundamentals, stay away from pump and dump coins.
This is because of the fact that holders are always warned against using a large cut method. The main reason is that if you are an experienced holder, now you do not see much of your holding. That is, you need to check the history of the market, you must first see that talking, they must be seen at all future gates, it can be a cutoff, and if something like that happens, you can avoid it, just hold on, since you are already known to be a myth in the long run.
