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.
Maybe what you meant is, "expect the worse" If you have invested that huge amount, well nothing you can do, if you bought an altcoin then, youre good as dead since its un sure whether it could turn back again. But if you choose good one such as btc, other famous altcoin such as eth, xrp, neo maybe there still chance. But if youre money is into new project then dont expect much. Just say goodbye with youre funds.
