That's the reality, many investors are more confident in buying the top 10 coins than buying new coins, even though new coins produce bigger profits than old coins, but also with greater risks. I already have the coins you mentioned above. BTC, ETH, ADA, SOL and will hold them until next year
I'm not really sure about this, as history has proven the opposite. In the top coins of the bullrun 2017, many coins were considered failures when they failed to achieve impressive growth in the bullrun 2021: BCH, XRP, LTC, MIOTA, XEM, DASH, XMR. Only BTC, ETH and ADA continue to exist in a strong way and are supported by the community.
This could also happen to the current top coins, including BNB, SOL, XRP, DOGE, ADA. The crypto market is constantly evolving, only BTC and ETH will always be the cryptos that receive attention and money flow from investors. Other ALTS will face many risks associated with innovation in the market.
