I would invest part of it in forex, I have been able to increase greatly my skills and nowadays I can get about thirty percent or more in a monthly basis... Fortunately, there are several brokers that accept bitcoin as a valid way to deposit/withdraw money, and it's a good option to be taken into account.
hi there mate got interested with your reply is this forex can be done day trading i mean you can get the results after the days end, 30 % profits would be a good deal if im the one who will going to give you that amount of bitcoin, OP would be happy if you multiply it right away after maybe a week or a month.
