I have seen the price of bitcoin is very high and has exceeded 15000 $ for one bitcoin, and now the price of bitcoin is under 10,000 $ and maybe this is my chance to buy bitcoin as much money as I have and hope to get enough profit for my economy in the future.
am I wrong with this step?
I don't think that this is a wise decision. Don't take too big risk mate. I think you should diversify your investment. I suggest you to invest your money in real business as well, try invest in stocks so you can get dividend atleast it is safer and still profitable.
