6- A card exchange for non blockchaind cards actually only blockchain cards are tradable with Book of Orb or other counterparty wallet/software it would be nice if players could trade non blockchain card for gold, crystals, gems (or for nothing, that could mean fiat money over the counter).
Actually it won't be possible with the current model for several reasons.
1. Giving ability to trade cards will bring fake account creation. People will grind early reward to get cards on an account and centralise the card to another big account and mass blockchainize cards. Also for the free to play balance we are going to give a small amount of good cards once the player progress. With the ability to trade people will take advantage of it to move to their master account.
2. Card have a real value specially when they are blockchainized if the trade exist and is centralized we will be held custodian of people belonging and an exploit to the database will be damaging.
3. Ingame cards are subject to fake purchase and chargebacks. Meaning someone will purchase a lot of cards and move them around then ask for a chargeback. It will be not a solution to freeze someone's account because it will be impossible to freeze the card that freely roamed around
Very valid points, glad some thought went into this already.
