Hodl strategy doesn't always work with every coin. We should only hold good coins that are worth holding like BTC, ETH. Holding shitcoins that are worthless will lead us to heavy losses.
Its true, different coin should be different strategy because have different fundamental. Hodling strategy only can implemented in good coin with big daily volume transaction and already have working product. Many altcoin in market are pump and dump coin and its not worth to hold for long term.
I couldn't agree more, there are many coins that are just not going to make it; you can tell from the onset and so holding them is not going to end well that is why one ought to invest in the right coins especially the ones with reputable developers and proper working product.
