For collateral i have guides containing information on homemade cocaine production, converting CC/PP to btc, Various Carding info, Phishing Code, and more. I'd prefer not to go into more detail unless someone is serious. There are 13 guides in total. Please email me at

ignoring the legality of the above ebooks, they are certainly not collateral. Collateral is something that you lose in exchange for a loan.
You have infinite copies of the ebooks. You will not be out anything, and therefore will not pay back your loan.
