Ether! Which is still most my most preferred altcoin list. Cause i used to saw it as a mother of erc Network and that time can't imagine any token without erc network where we needed to give transaction fee with via ether! That means, more use of ether, will grow more value of it. Thats the reason why ether still my favorite altcoins list. Same way i used to love bnb for bsc chain while i found bsc also trying to be the next ether
Ether is also my favorite coin, but really regret not buying it for under 1.5k a few months ago but I expect market conditions to correct in q2 to increase investment assets paa ether, besides that I also focus on investing in BNB coins, both coins are highly recommended and safest altcoin for long term investment without any doubt of market impact.
