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.
Altcoin investment is too risky especially when the market is in a deep bearish. Some may look very tempting because of their cheap value but the question is if they can survive if the market remains to be in a long term bearish. I believe those who don't have real utility cases won't sustain their value and eventually get lost in the market. So do not take the risk investing in altcoins particularly if you are still a newbie. Instead, stick on bitcoin and invest for long term because its the safest investment that would make you profitable as long as you sell it at a high and reasonable value.
