Looking as to why bitcoin is down
down and up it's like everyday in cryptocurrency but if you want to know more maybe it's cause the microsoft company not using bitcoin anymore didn't know why they don't use it anymore. but the price going down and up it's an usual activity for that just wait until the price back again
I don't think the current price fall is not due to that microsoft's announcement because i don't think that much of people using bitcoins for buying microsoft products.The price crash is maybe due to the ethereum price bump so people are transferring their bitcoins to ETH to make more money and I heard that there is a ethereum fork coming up at the end of January so people will receive free coins thats why more people are moving to ethereum but this price fall is not permanent the price of bitcoin will rise soon so grab some bitcoins when the price is cheaper.
