Will you guarantee the results for at least doubling your bitcoin?

If so, you could probably find someone willing to purchase, if you guarantee (and escrow) an equal amount to what they plan to use to attempt to double or triple, and if they are unsuccessful with your guide, they get paid the remainder out of escrow.

If it's so successful, why are you selling it for 0.1 btc instead of just performing the steps over and over?
