Hodl strategy doesn't always work with every coin. We should only hold good coins that are worth holding like BTC, ETH.
Holding the top few altcoins along with bitcoin is always the good mindset. Putting your money into every new project that jumps up is only going to be a headache and a waste of time and resources because of this current market being non-productive to any ICO. However one could try investing in other sectors which are also being bearish and stay away from crypto for a small period of time. It could be a good knowledge building exercise.
Holding shitcoins that are worthless will lead us to heavy losses.
The heavy loss already occurred when they bought the shitcoin.
