disappointments, this is the big reason. You see, people when they create high expectations, easily have great disappointment on the day that those high expectations are not matched. Last year the price of bitcoin did not stop rising and then the price fell from $ 20,000 to $ 6000, People were disappointed and left cryptos. today the demand is very little and not even good news are not causing the price to increase. Then we have the governments with their regulations, we have many ICOs created by scammers, all these facts are causing that there are no more big price increases. But this also has its advantages, for example: the price of bitcoin is stable.
