I can offer the mining hardware itself as collateral. If your asking if I can secure a loan with funds that I already have then there would be no such security. If I had the funds I wouldn't need the loan.

I do have an account with a certain company that generates a consistent amount of cash money everyday. Current earnings are less than enough to cover the promised payments but I can increase the revenue to more than enough to cover the indicated payment amount with a portion of the first 20 BTC (which is part of the reason I would need the 20 BTC seperately.). I would be willing to give John K. complete control over the account including the resetting of the password and email account to allow him to manage payments, although doing this would be a daily task on John K.'s part, so I am sure that it would increase the cost of the loan so terms may need to be changed to adjust.

Additionally, once the loan was completely funded and dispersed I would be more than willing to let John K. share all of the details with the loan provider so long as the loan provider was willing to reveal the same information and sign a confidentiality agreement, I would also agree to sign such an agreement for the loan provider as well.

Do you think that that would suffice?
