I never would imagine that the bitcoin price would be 4000 this year. Before I knew it bitcoin at the price of 1000 but at that time I ignored it.
this year I tried to invest in bitcoin even though the price is expensive. But i still gained some money.
You should know bitcoin price in this year has reach over $4500, bitcoin is the best investment in 2017 because this year has recorded history with the highest price bitcoin achievement of all time.
