Here is my simple answer JoelKatz. I want this exchange more than everything, and I need starting fund. I'm a new member here and an exchange business is risky, so I thought if I offer a pretty large interest rate, then bitcointalk lenders will support me.
If you're lying, scammer. If you're telling the truth, fool. The absolute worst imaginable way to start a business is by borrowing money at exorbitant interest rates. And the very worst imaginable way to induce people to invest in your business is to offer them exorbitant interest rates. This almost ensures that your business will go broke if it encounters even the slightest problem -- and new businesses always do even under the best of circumstances.
