I dont know of this sure but there are a lot going on that seems to be affecting the Bitcoin price right now, and not just bitcoin but every other assets and stocks market.
There is Coronavirus fear and it seems to be affecting everything, the price for everything has been decreased to a very low, Bitcoin has fallen back to around the rate of $7,000 after making its to $9,000 plus and apart from that miners has been another case since they started selling out less of what they mined. There are still a few other things that may have possibly affected the price of Bitcoin and caused it to fall.
Of course the global crisis in the health sector caused by the novel coronavirus has hugely hampered the economy. All businesses are directly or indirectly affected now, whether we admit it or not. And talking about the crash in the crypto industry not affecting only Bitcoin, we know Bitcoin leads the industry. If it bleeds, the rest bleeds.
