Well mostly to send money and do business that I have better control of but there are other reasons as well like buying to let it seat on my wallet and waiting for the price to reach the sky before I start selling them and earn good amount of profits.
I buy Bitcoins to hold so that in the future I can make a profit. It is going to take a while before the price is somewhat high enough. But when it comes to Bitcoin you have to keep being patient that is how you survive.
