Steps to making money at DA.
1. Challenge someone to a duel for BA. Set an arranged time or challenge them on the spot. You must ask if they want it to be a single or a match.
2. Win the single or match.
3. Post your win, and get confirmation from your opponent that you won. If you don't trust them, just screen shot the win and the agreement to duel your opponent.
4. Get money!
And that is how you start the making money process in Duel Academy.
