I've a 100% free risk method (repeat 100%) that will give you a profit 0.35 BTC per week, by investing 0.25
Nothing is 100% risk free.
What I Ask:
1) You must to be an highly trusted and well known user, not less than senior member
2) You need to keep promises to send me 0.05 BTC per week, for the first 2 weeks (so you pay only 0.10 BTC). You will pay me at the end of each week (or before if appreciate ), so you no need to send coin in advance.
Why don't we do it like this: I send 0.1 straight away to an escrow, I review your "method" and we take it from there...
At least you didn't post any questionable links
