I have been observing a trend from last year bitcoin price movements to this year movement.
I have observed how we're getting so much positive news and adoption about bitcoin this year, but still the prices refuse to go up. If this was last year a single positive news will have pumps the prices by at least 10% or more.
Its that positive news don't longer have any effect on the price movement or is their any manipulation going on.
Good news of course has impact for Bitcoin price even today, but the main problem is the extent of speaking.
Year ago , or couple years ago the people speak much less about Bitcoin and when people have hear more and more about something, then those news starts to care less and less to them. So there is the main problem why news don't longer have so huge effect on the price movement.
