You say guaranteed, so no risk, but if that is true... you wouldn't be needing our bitcoins, you would just use your own and keep all profit. Your offer just doesn't make sense.
What I mean is that I am taking the risk...I have plenty of bitcoin and if I don't make profit from your investment, Then I will cover it out of my pocket...so for my investors it is risk free (guaranteed)

Okay.... let me think an hour or two about it. Maybe I will give you the benefit of the doubt
