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.
As a person who has not experienced losses from Bitcoin's decline, I agree with you. I hope to get some low-priced chips, take this opportunity to get on the car, and make a 3-5 year plan. The basic investment method is to buy $150 of Bitcoin on the 20th of each month (salary payment day), Maybe it will continue to do so in the future. Every March, I take out a little bit to buy my wife a birthday present. Finally leave it to my kids.
