I think everything you write is true, the first from news from all over the world that discusses issues in a country about positivity and negativity about bitcoin that can affect the price of Bitcoin. and secondly I have bought a coin for hardfork, I think prices will rise because there will be many people who buy hardfork coins, you know for yourself that when hardfork happens we will receive coins for free. but it turns out the price has decreased very deeply. and it is beneficial for people who buy at cheap prices, because prices rise again quickly. so what you write can all affect prices on the market,
