When BTC reached $69000. I didn't choose to sell it. but the current price of Bitcoin dropped to less than $30000. Is it the most reasonable choice to sell BTC now and turn your attention to other investments? I hope to get some good suggestions. Although I have held BTC for many years. I am not good at management.
If you haven't sold bitcoins when the price is $69000, why do you want to sell bitcoins when you have a price of $30000? I think it is not a good decision, the best decision is you sell when the bitcoin price is $69000, but it's too late so why do you want to sell bitcoin when the price is $30000? if you need money, you are free to sell your bitcoins or sell some of them. but if not, maybe it's better to hold your bitcoins.
But all decisions are yours. So, do what you think is good and adapt it to your needs.
