I am opening a bank, the Royal Bank of Jarton! I am gonna explain how it works here. Imagine that one user deposits 30k, and another deposits 20k. The Royal Bank of Jarton loans a user 50k, with a 70k payback. The amount user A recieves is 36k, his 30k back, plus 3/5 of the interest as he deposited 3/5 of the loan. The amount user B recieves is 24k, his 24k back, plus 2/5 of the interest by the same model. The Royal Bank of Jarton makes 10k, half the interest. If you are scammed and part of the loan is paid back, the money is divided by the same model. Any late fees are split between the bank and loan partners by the same model.
Unfortunately I do believe you're going to get nowhere with this. I'm sorry but the lack of effort just goes to show how well things might go over if I or anyone else decided to give you a hefty amount of money. Try to come up with a better business model mate.
