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.
If you are holding up your coins and the market experience a big bull and then later the bear season come and the price dip drastically for sure if you are not strong enough to withstand the pressure of which the market drops you will be forced to sell off because the market will indeed deep very much but it will still be seen as a wonderful opportunity for those big time whale or hard investors to buy even more Bitcoin and keep it for the bull market to come again some time in the future.
