Freebitco's APY was good and nothing extraordinary while Betfury's APY is ridiculously high and is really a sign of a problem because coin with 100% APY or higher will devalue and won't be able to increase in price. Btw Freebitco's problem was that they bought FUN and then didn't try to work on its marketing. There was zero marketing effort put on making FUN popular. Also, transaction costs were very high, price started declining and Freebitco's impotence killed FUN token.
