Except for bitcoin and ethereum, when investing in any altcoin I think we should do thorough research before investing. There is no guarantee that the top coins on CMC will not crash and be forgotten. Although currently they are considered to be worth the investment like Sol, Avax, near ... are all very good and potential at the moment but are you sure they will continue to grow as the bear market lasts.
They all will not grow well if Bitcoin is still experiencing a decline like now because almost all altcoins that already have potential today are still dependent on the condition of Bitcoin so when you exclude Bitcoin and Ethereum for investment, then it is a very wrong step because both are always in very good ratings even in crash conditions though.
bitcoin still dominate in market and influenced all cryptocurrency price . up or down on bitcoin price will give same impact to altcoin , and current condition could be simple example how this work. we have to analize bitcoin movement if want to invest in altcoin , both of them have corellation and influenced each other.
