You literally open an account, buy bitcoin and they do all the trading for you with their trading software. i'm not 100% sure on the monthly percentage, but they pay you 140% back on capital over a period of 140 days which averages at 1% daily return of whatever amount of bitcoin you choose to purchase. The site controls your bitcoin trades and the robot but if you're not comfortable with that, alternatively you can purchase their forex robot and open an account with a third party(broker) and have full control. Also the bot is set on low risk in order to provide a steady consistence flow of income. This is just based on my own research of the company but i can PM you further details if you like.
