Its your personal decision OP. Undoubtedly Ether will be the best altcoin again in this year as well as it continuously developing. That's why i assume, $5k won't be a big deal for ether to grow if bull run start with its full energy.
Says who? Ethereum being the best altcoin this season is misplaced, it is evident with the way many altcoins have behaved already. If it's for it to still maintain the number 2 rank among cryptocurrencies, fine, it may still achieve that. But when it comes to trading, investment and return, then you are not being sincere at all. It's all about the money we make from these cryptocurrencies and I wonder what you have to say about the wonderful cryptocurrencies like SOL, BONK, INJ, PENDLE and many more? I can still comfortably mention 35 coins/tokens that outshined Ethereum and will continue to outshine it.
It is your choice though, but for me, what I can do with Bitcoin and Ethereum at this point is to trade them on the futures market only. Relying on the return they could earn me through investment more than what many other altcoins can do will only amount to a self-deceit.
