If at the time you wrote this article, you invested in Bitcoin, now you have earned a lot of money from it. If you study the market cryptocurrency will see the Bitcoin increase or decrease in a certain period, but often the rate of increase is very high but decreased only slightly reduced. According to my experience, when the BTC suddenly drops as you wrote, I will always buy BTC for holding and wait for the BTC to increase the price to make a profit. At present, the price of BTC has reached the threshold of 19,000 dollars, promising to exceed $ 20,000 by the end of the year.
