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.
For me it is not a good move if we hold coin in the market, the reasons are first before you become a successful holder there are some projects to be released with the same purpose, second most of the alts in the market does not have chance to prove themselves because investors does not want to invest to a coin that the ICO has done already for a long period of time.
