The exclusion from being a digital currency business for online games,
> (2) Online games or gaming platforms that use digital currency that (A) have no market or application outside of those games or gaming platforms, (B) cannot be converted into, or redeemed for, fiat currency or digital currency, and (C) are not redeemable for real-world goods, services, discounts, or purchases.
raises a question. First note that the three qualifying conditions are joined by AND, not OR, so it seems a game must satisfy all three to escape being a digital currency business.
For (A), "have no market or application outside of those games or gaming platforms", is that limited to official markets? Many an MMORPG has tried to keep their game currency game only, going so far as to ban accounts that are caught trading game currency for outside currency, but nevertheless markets outside the game for their currencies have invariably arisen. If unofficial markets are sufficient, I wonder if any significant game will be able to qualify for the exclusion.
