Technically for someone who wants to purchase more BTC, and has been awaiting a huge dip he obviously will love it and will be Happy since he gets to buy more and await for the bull seasons. But for someone who already rushed to buy during the bull hoping that he could make quick profits or think that the bull will just go on like that. He will not like the bear as his investment will be in the negative directions. Let's just say the best time to enjoy Bitcoin investment is buying at a low price and waiting for the bull seasons. But no one really will enjoy the dips after a huge bull. Except for the long term investors whom the market fluctuations might not even affect their investment capitals.
The fact is that bitcoin is profitable for long time investment and an investor don't have to wait for only dips to buy BTC except he is buying with a huge amount of dollars to take profit within a short period. But if a person is using small amount of money to wait for a dip like this recent when bitcoin fell below $56k and later moved to $69k+ such person can't make any significant profit, for such investors the long term investment through DCAing is what will be beneficial for them in the long term which they won't have to worry about market fluctuations.
