i think i can agree on this one, if he wants, he can check the number of online people in betfury. though it is not really a measure of how many players are active, but you will have an idea how many are visiting the casino. also, they have in-house promotions. if he will try playing the $150 funfury competition held every 12h, you will see that there are thousands of players in this contest alone. you can see your place once you start playing using their free funfurytoken. so right now, i don't think sig campaign is their priority. they may hold it again if they are seeing very good advantage of it.
They already relaunched it some time ago and will probably relaunch it one more time when there is a new big event! I like the Funfury competition in fact, it is free and I already ended 3 times in the top 150. Most of the times I get busted right away, but some days everything goes right and I keep wagering with the FUNtokens.
