Ugh. Provide some actual services/products. This "send me $100 and I'll send you $100 back" bullcrap is pointless..
A confidence man could work his way up to 100,000BTC before he runs away with it. This proves nothing.
No one would lend me 100,000BTC because I pay back 25BTC.
The reason I choose 25BTC is because most of my items are around that price. So customers would trust me.(Of course, lenders do not need to trust me if I ever want to borrow 26BTC)
And browsing 25BTC could prove that I'm trustworthy when customers buy things from me. (My items are around 25BTC, so it's not like paying back 100BTC and ran with 1000BTC)
