How do we know who to ask and whether they are capable of answering the question?
When you want to create a question, you need pay some amount of ASK as reward, when someone sees your question and replies to you, if you're satisfied, you can decide to reward that response, you can also decide how much to reward on each reply.
In the future, we will also develop a built-in decentralized exchange that will allow users to initiate P2P trade directly on the askcoin app
