That's why you should do your research first before buying some coin,so that you don't get a shitcoin later.For bitcoin,hodl is not bad because we expect a long growth,so it's better to hodl instead panic sell,where you lose your money before the price up again.
oh my biggest mistake was i bought a shitcoin without any research and got rekt bad lately. hodl doesn't work for shitcoins and semi shitcoin only for bitcoin and few othe solid coins.
