Of course it does it could make the price of Bitcoin to go up,
Any news could affect the price because it will trigger the decision of the investors .
It is like the real estate market, the good news is that the price will grow drastically and vice versa. This is the information and communication age, all information will more or less determine the direction of the market.
You are right about the positive news affects any business or product in better way not only real estate goes better with positive news but almost all the products go better with positive news.
