I was just looking at the coinmarketcap table since 2013, I was surprised in what I saw, many coins topping the charts then are now almost non-existent, we need to be careful of the kind of coins we hodl especially for long term. Most of these projects just die after the initial hype.
With investing in altcoins, you need to have a short term investment plan and strategy rather than thinking of going in for a long term plan. Altcoin market is very volatile comparing that to Bitcoin. You can easily lose about 50% of your investment capital within a matter of seconds if you decide to go in for a long term plan.
