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.
This could be right and at the same time, many investors will also lose a great part of their investment investing in new Alts projects thinking that that is how new projects always give good returns. Outside of Investing in Bitcoin, Ethereum, BNB, and a couple of others that have held up well through some bears seasons, others might fail and worse are new projects.
