This is not my recomendation, just my personal experience: I have hodled bags, pretty heavy bags of what could be considered pretty much shitcoins, for 1+years, checking the portfolio daily, and it's pretty much guaranteed that your bag will get a good pump where you can unload.

The only thing you can do is hold or sell at a loss. BTC is the only long term holder, ETH, ETC and LTC mid term, probably you can add XMR too, everything else starts being insane risk tier.
