In the end, there will still be a profit, but those who bought at a price of 40k and above have regret, because they could buy now at a lower price. On the other hand, it is easy to do in theory, but it is more difficult to implement it in practice. No one could know at that moment how low the price would fall, or if it would fall at all. What if the price continued to rise and up to 100k?
This is always difficult, so now all that remains is to hold and, if possible, buy bitcoin now to average the price.
those who bought bitcoin at $40k and held it for now may be holding it for the long term and buying again at a low price now. The decline is indeed very drastic, but if the resilience of the capital allocation to buy bitcoin is still available, you just need to wait for a lower price to buy again. and for sure the main target must be more than $ 40 or the target on the new ATH again. and the money used is free money and is not used for any future needs. when the time comes when the bitcoin bulls return, then just need to take a lot of profits. just need to be patient and apply good strategies and do financial management.
Even though Bitcoin is now down at $18k, those of us who have bought at $40k or even bought above $40k don't need to worry. Because Bitcoin
will always recover and can rise to new ATH in the future, after all, Bitcoin has repeatedly dropped to very low prices. What we can do as you said
we can only hold the Bitcoin we have and wait for the Bitcoin price to rise to the price we want. My advice is to hold Bitcoin until the Bitcoin
halving occurs, usually the Bitcoin price will rise very high after the Bitcoin halving occurs, and long term investment in Bitcoin is very good indeed.
We if we still have extra money can buy Bitcoin again at the current price or we can buy Bitcoin every time the price drops. Because accumulating
Bitcoin it would be very profitable to do, after all, Bitcoin is the safest to buy when there is a bear market like now.
