With BFG as far as I know there are more users got who their token in investment thru the campaign they did. I'm not sure who profitable it is when the revenue is shared to the holders. But I would assume it is profitable since Betfury becomes popular.
What is to worry with casino token is that they are not listed on big major exchanges. I don't see it going there like it is innovative enough for the tech loving guys out there. This is the kind of token that will serve more for the team.
They did a big bounty campaign 2 years ago where they gave away a nice amount of BFG, but the majority of the tokens has been mined by playing the in-house games or third party slots. If you browse through the Betfury topic, you will also see that they are working to get listed on some major exchanges (including Binance). It will take a lot time but hopefully they will get listed.
I remember those bounty campaign and I regret for not joining it because most of bounty campaign that time is scam so I got scared on joining any of them. Betfury launch signature campaign multiple times this year and last year aside from there bounty campaigns. They have the money to have a decent marketing and partnership, I guess binance listing is very possible on this casino tokens.
