Maybe not all, but there's always a correlation that keeps repeating itself. Sometimes the news gives us opportunities and losses so we have to be wise to take advantage of it. If there is no news then can we imagine where the price of bitcoin goes? Will it keep going up? Or vice versa?  Or will it run flat? It's going to be boring. If that happens then we will find it more difficult to find profits from trading.
Like bitcoin is meat then news is the spice that makes it sweet or bitter. What is clear is that as long as I know bitcoin it will always be there, we should be able to take the opportunity to take advantage of it.
