BTC is currently trading on 13774.09 US Dollar and still going downwards at least for one day because 15 hours ago its price was more than $19,783.06 this was the price of BTC on December 21 and this is at least 10% dropping . It is dropping because of its rival Bitcoin Cash. Because Coinbase allows trading in Bitcoin Cash. So my suggestion for you that if you are looking to buy BTC don't buy it at least for the couple of days because it will come down more.
Thanks
