Since getting know bitcoin in 2017, I make much profit from bitcoin, because I have never hold bitcoin for long time, unfortunately last year since the price of bitcoin dropped, I only left a few bitcoin, so this year I dont get  much profit from the price of bitcoin now. maybe if I didnt sell it last year, I made a lot of profit this year again. but  looking the price of bitcoin now, I will go back to buy bitcoin again for get a big profit.
