Well with most of the FUN under their control, I do expect some of the changes that could happen is that under the fortune of wheel we may soon have Fun tokens to be up for winning. Also, in wining lottery we might have the fun tokens to be won rather than btc which is now. Though this change depends upon admin if they want to introduce something like this.
Good idea, just now you can easily exchange it for FUN token if you got 320 or 3200 satoshis in the WOF. Maybe, if they approve your suggestion between 5 -50 FUN tokens could be listed on the wheel. Also, buy-sell token still available on site, you can play by multiplying it using btc and come back to the page to buy FUN token.
