I am selling this guide on how to double or even triple your bitcoins in 3-5 days to only a limited number of people.
This guide cost only .1 btc and is GUARANTEED to double or even triple your bitcoins in 3-5 days.
Can you tell me what collateral you will provide that would be equal to three times my current BTC?
I'll take you up on your offer but I'll expect your guarantee to be valid.
