As November 2022, I think we are really arriving to the end of downfall. Its gonna take some more months for Bitcoin to truly recover, and Ethereum/BNB to react it. Especially Ethereum supporters will start making profits next year. I am planning to divide my portfolio between Bitcoin Ethereum BNB and Solana for now. But I am at waiting side for downfall to end completely. Situation with coin markets seem stressed now.
diversifying should have happened from the beginning of investing mate, while we must hold majority in bitcoin yet we must have shared with altcoin like those you mentioned that is well supported and stronger in any sense .
so indeed you must divide all your coins nowadays mate.
