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.
It's not fair to take 2013 as a point since back then, cryptocurrency was quite young and immature. Not many good coins back then so there's a reason why they've gone if we looking at today.
