I won't mind if bitcoin has fallen by more than 60% it will definitely return to its best price again whereas if altcoins have dropped after or more then I will be worried it is difficult to recover even though they have developed several programs, a little what I understand altcoins wouldn't add too much value to my portfolio except ETH and BNB which have been around for a long time whereas for new projects I don't want to jump back into investing in them.
There's no guarantee that even if they have a blockchain developed I won't be interested at all, so for 2023 my plan is to see a breakthrough in bitcoin price movement.
