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.
There are certain factors that keep an altcoin from reaching its highest point, for example the strength of the coin is weak and even the coin is a meme that doesn't have a community to support it.
altcoin rankings do not guarantee that they will be priced high, or they are not a benchmark against altcoin journeys, because basically almost every time a new coin is launched in the market, so coins that have no power will continue to lag behind and die over time
but altcoins from big projects always have the backing of market forces. when the bears come and break the market trend, many people will aim to own more bitcoins. some even sell their altcoins to get bitcoins at a cheaper price. the main reason is faster returns from bitcoin.
It's not that the big altcoins in the market aren't worth holding on to in the long bear momentum. we could have a potential altcoin for a long period. it will give a nice return when the market turns on a bull trend.
