1. Many altcoins will never reach their all time high again.
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.
With events like now we can judge that the rich have started to enter the crypto world, many investors have broken out, each of them wants to create their own coin, wishing to do the Fort market on their own, in fact, all of that fantasy never materialized and died.
With the concept of investors without considering market risks and the coins they create, many of them run into debt, because of their projects, I think in the future Bitcoin, Ethereum, BNB can still be relied on.
