In my opinion it's better to make a separate wof for non-premium users with different rewards or the same rewards with lower chance of winning big prizes.
Premium users with thousands of Funtoken in hand(bought at higher price) deserve to have better chance in wof. Multi accounters are milking wof and you lower the chances for all accounts, this isn't fair.
Yes, I agree with you, otherwise it doesn't make sense to invest in FUN tokens anymore, unless you are a big bitcoin investor who will benefit from the extra daily interest feature over your bitcoin balance, because it's no longer possible to rely your investment on the wheel's returns.
Now besides FUN price going down you can't recover your investment decently through the wheel too. I know the site can't give more money than they earn and that it's their right to change rewards' rates anything they want, but it's an undeniable fact it's a quite frustrating situation for investors.

Nobody buys FUN expecting the rewards will be drastically reduced overnight.
Yeah, FUN is really going down and it's not doing anything what we were expecting from it. I think it won't cross 0.14 USD line but in the beginning there was so positive vibe around FUN, idk, it seems very hard or almost impossible for it to succeed. As far as I remember freebitco bough the supply of FUN when the price of this coin was 0.3 USD.
If the price won't rise, I think they have to change the FUN promotion to make it more profitable, start very aggressive marketing or idk... If this continues so on, the most positively felt old buyers will even lose the faith.
