1 FUN = 24 satoshis. It was 1 FUN = 36 satoshis months ago (last September I think).
That's because the value of bitcoin prices is getting higher on fiat currency exchanges and while FUN is relatively slow on fiat currency exchanges, therefore the exchange for FUN to BTC is getting lower, but judging from the total FUN investment at the beginning it would be better to calculate it at the exchange rate fiat currency than calculating it to the exchange rate to BTC
