remind us what the project is ?
and more importantly, where do you get the funds to pay people back ? is that from the project ?
and more more importantly.. what if the price of btc goes back to $1200 overnight ? could you still afford to pay it back ?
I have started local bitcoin hand-to-hand exchange service. All funds to pay back will be gained from the project. Most part of coins will stay on wallets. After each transaction I will fulfill amount of coins as fast as possible. I'm working together with my brother and his son, so we are able to monitor bitcoin price 24/7 to prevent funds loss.
Can you provide a bit more information such as, what (in outline) is the service you are offering that will allow you to guarantee such returns? Where are you operating? What are the regulatory risks (if any)? How have you estimated your market? What collateral can you provide?
