After spend one year in cryptocurrency field i realized that when bitcoin price drop suddenly 40 % below to its current price it the best time to buy bitcoin, for example in December 2017 bitcoin price reach 19500 dollar and in February 2018 bitcoin drop 6500 dollar, if drooping price bitcoin again raised and reach 11500 dollar, in April 2018 price drop 6900 and again raised and reach 9500 dollar.
So i think this is best time to buy bitcoin and sell bitcoin 10000 dollar approximately,
What you think please comment and share it
