Obviously you don't understand how loan economics work, no individual, no bank, no institution is going to give you a loan unless you can demonstrably prove that you have the collateral to repay it, if you fail to repay it your collateral becomes the property of the lending party.

If you had an asset that you knew would double in value within the loan term, you would clearly want collateral that covers the final loss amount should you default on the loan (which is highly likely given the failure rate on this forum).
