You should wait a little bit because bitcoin is now a bit of high. So if it drops to 6k you will buy it because you can have more profit by doing this method. My friends are also waiting to do a investment.
I will invest when it will fall down because you can make more money.
Better to invest now before Bitcoin goes really high. It is Very much difficult to buy a whole Bitcoin even now. The experts predicted its value to be somewhere near $10,000 by the month of April 2018. If you ask me I think it will be a few 1000 dollars more than that the previous prediction about Bitcoin was that it will be worth $7,000 before the end of this year but it already is of 8000 dollars.
