I doubt many would buy it.
A subscription is a mindless thing...it just happens, at least for most of us. We either do a 6 month or a month-to-month. No one pays close attention to it. Buying a token, though, that's an active thing. You think about the cost. You think about the benefits. It requires you to purposely buy it, sell it, and wait for gold...and what do you do when you have little need for yet more gold?
