The main thing is that this surprise was not negative and the price of Bitcoin does not roll even lower. Everyone is waiting and believe in a miracle)
Why everyone think that correction is the surprise? I think that it is the normal behaviour of the market, fallen in price after a huge growth.
I expect it will fall further but long term I have faith. Some cool projects emerging next year which i'm excited to see, hopefully can take cryptocurrencies to the next stage as a usable asset instead of a store of value. Plutus will be dropping a crypto payments app that lets you tap into visa and mastercard infrastructure, makes crypto usable at 40 million stores worldwide which is pretty crazy. Until we have projects like this that fulfils the "currency" part of cryptocurrency we'll probably lose mass interest for a while.
