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 was a disturbing sight when I looked through. Only about 250 coins are currently active in the cryptocurrency market the rest are dead or near dead. Something has to be done about these altcoin Proliferation which defaces the cryptocurrency market
