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.
Patience is virtue in crypto but know what altcoins you will exercise your patience on. Many altcoins are not worth waiting for. It is very easy these days to see through these projects and have a clear vision if there is still prospects in them. That's why I advise, always follow up on altcoins that you put money in and check from time to time if they are alive. Don't just hold for the sake of holding or on ground to patience is virtue. Sell if you smell death in the coin and move on.
