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.
You didn't sell when the price reached $69k yet you're thinking the price below $30k is reasonable to already let go. What made you think that way? Are you tired of holding?
If you hold your Bitcoin for many years (as you've said) then you're already aware that the price currently is just temporary. So if you're selling at the current price, you became a weak investor despite of being a hodler for years. Anyway, it's up to you though since we have own way of thinking.
