2. Don't be fooled by altcoin ranks on coinmarketcap because many won't stay in top 20 anymore after we go deep into this bear market.
3. History have proven that many altcoins will be replaced by new ones and that's where huge investors will be making most of their gains in next bull market.
I only partly agree with you here. There are definitely examples of coins that were in the top 10 a few years ago but that are now in the top 50 or even lower in the coinmarketcap ranking so of course just because a coin is in the top 10 or top 20 now does not mean that they will still be there in a few years. That being said, i have a very hard time to imagine that coins like Ethereum, BNB or Solana will really become completely irrelevant. I mean even if they are losing their ranks in a few years to other projects then i would still expect them to have a higher price then in comparison to at the moment.
