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.
I don't think so, not all coins are created equal, there are coins not worth holding, there are two kinds of coins, coins that you are going to hodl and coins that you will dispose of, and you can differentiate these coins by how they develop their platform and how good is the volume in the market.
yes, for coins that are truly unfit to hold must be sold as soon as possible before they actually lose value and are left behind. even some that are already registered in the exchange can also be a scam.
