I'm looking for a places where I can invest bitcoins with high leverage.
It should be something reliable and use well known derivative instruments like futures, options, forex, etc.
My personal preference for short term investments.
I'm using
liberoptions.com but I need larger bids.
Any suggestions?
Try investing in bankroll of casinos or of coin mixers for short terms.
They provide about 50% ROI yearly on your coin and most of the time can withdraw at any time.
