bitcoin is too sensitive to news. if there is negative news, the price of bitcoin will immediately drop. years earlier bitcoin rarely received negative news, but this year negative news came in succession.
It's correct. This market is very sensitive to news and can be seen as a news-controlled crypto market. All cryptocurrency fluctuates when news hits the market and bitcoins too. We can see that in 2018 there is too much bad news and it causes the prices of bitcoin and altcoin to fall very deep compared to the end of 2017.
