You are saying you are going to reduce the time until a human interaction would take place, when there are a dispute and you compared your service with Localbitcoins response time, but you hardly have even close to the active users than what they have. I reckon they too had something similar in mind when they started out and then it exploded and their support staff stayed the same. (This usually happens with small startups and it eventually kills their business.)

How are you going to prevent that from happening with your company? Can you scale the support staff as you grow or are you also going to go the same route as the companies before you? (Perfect example = Coinbase)
