Why wont you hold both instead? If you have bought these coins a year ago then for sure you are already in profits if we do try to compare the past price and the present time price
of bitcoin and etherium and for sure you are on the profiting side unless if you do decide to convert those ETH then switching up to btc then its your choice
but hey diversifying is always recommend so its still your choice though.
We shouldnt try to compare both different markets because bitcoin can move without relying alts or entire market condition and same goes with ETH.
If you do want to max out possible profitability then going for both is the best bet.
Exactly, to be honest i am only dreaming of having both ethereum and bitcoin in my own hard wallet and i will choose to keep both as my long term investment. I am so amazed with these two cryptocurrencies and in fact thinking that you have already purchased your own ethereum and bitcoin a year ago before bullish market were amazing and if you able to make it grow or even you just kept it in your wallet then your 20 ethereum and 1 bitcoin have already a great value.
