Can you give some more info about guarantees?
After the market has seen several ICO's fail because devs run off......
How are you going to assure the investors that you don't run away with the BTC when ICO is sold out?
From my point of view, if you (or the exchange) can't give any guarantee, it will be hard to sell all your coins.
The market seems to be quit affraid right now.
