1. Many altcoins will never reach their all time high again.
This is true and I've seen many coins at the top 10 a few years ago that aren't in the top 10 or even in the top 50 anymore. There are some top 50 coins in the past also and some of them aren't even in the top 100 anymore. I still can't forget EOS since I'm a big fan of it. I'm lucky that I didn't bought some when it is at it's peak at around 20$ back in 2017-2018 because even though we had this bull market, it didn't reach that price anymore.
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.
Almost the same as the first one.
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.
Uniswap, Polygon, Solana, Polkadot, Binance Coin.
That is only few of the top coins right now that aren't in the top a few years ago. We don't know what coins will emerge in the future. We might see bottom coins right now that will go on top and vice versa. We will see projects that will came out of nowhere and will be on the top like Polkadot. It's unpredictable and that's what's good with crypto market
