few points:
- This is not an exchange like bitstamp. I might not been clear. It's a place where people can buy or sell coins from/to the site, not to each other. Users won't have funds on the site, but only my bitcoins will be on a 3rd party bitcoin-supplier-per-purchase site.
- Obviously im working with a lawyer to have proper working procedures to obey by state regulations. So KYC would be part of it, specialy for cc transactions, and aworking procedure will be written.
- I'm hiring a coder to do the site and he's well aware of the security implications.
- If I want to stay compatative I must make cc payment instant. I have no other option about this, or I'll lose customers.
The part where you mention KYC will probly turn off some of the potential clients as many users of Bitcoin would like to remain anonymous. I know there are exchange sites out there who are still up and standing regardless if theres KYC or non. There are Bitcoin users out there who are paranoid when they hear those 3 letters.
