This market is always full of surprises, last year everyone was expecting a fall but after october bitcoin continued the rising and in 1.5 month it passed to 19-20k dollar so now everybody is saying that market will see 3k dollar and it can do big rises like previous year.
The market is full of surprises but the surprise only last at most for a few days, then after that period people should be able to react to the market, I say this because some are very slow to react to the movements of the market and that can be very damaging especially in a market that moves as fast as the market of cryptocurrencies, so while people could have been surprised about the rise in the price of bitcoin after segwit got activated, after a few days they should have understood that we were about to see a huge bull run.
And the same happened with the crash, when the price of bitcoin was going down I understand if some were surprised the price did not went any higher but after a few days of the price going down they should have understood that the bull market was over.
