Holding is the only way for altcoin investors now unless you want to accept your losses and exit but its better to have patience, i have seen coins that worth 1,500$ a year ago and they are now 200$ , i have sold airdrop tokens that should worth 150$ for 10$ to sustain but i am not stupid enough to get rid of all my tokens and coins because market is not in my favour, be wise and remember that those tokens you are getting dispose off can turn something when market start turning for the better, be determined to win,when thinking forward always think backward as well.
You have a point but you might be better off actually looking at the project's status instead of just speculating. Is the project making progress? Are updates being posted, is their blog active? There are lots of things you can do to determine if a project is worth waiting for.
Obviously if nothing new is said about the coin you are holding then the developers have probably already made an exit, so you know now that you should stop hodling nothing and sell!
l agree with you, This comprehension doesn't belong to this world. Sometimes, unfortunately, everything can happen in this world. As you above mentioned, patience plays a major role in the crypto industry. In any case, this event absolutely will change and this statement can make me motivated instead of thinking backward. This is my personal opinion.
