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.
Actually every investors can't be at same trends of being attracted on a particular market phase, there'd surely be some who had bought buy the Dip and holding for the bull while some even at the Dip will be hoping for a Dipper before they'd buy. Then also, some who already bought at a high price would be hoping for increase of bitcoin price.
It's all just full of biased and sentiments because while some are already holding to make profits, some are craving to buy yet which is a sentiment of either Dip to buy more or bull run to profit. This basics is actually the basis of bitcoin being a volatile currency and its future market prices can't be determined.
As you expect market pricing is very unpredictable and you have to burn a lot of time for dips or bullish. Bias may be ok but not for everyone. You may have bitcoin holdings and expect the price to rise further but dips are definitely expected for those looking to buy more. Basically you have to trade through this to achieve the expected profit. Considering the volatile market, your best decision may be to buy a few times every week or month and buy aggressively during dips. Regular buying will make bull runs more enjoyable for you and dips for you to be aggressive.
