This isn’t surprising, since a gambling platform is clearly not the kind of place where users would like to take out loans collateralized by their other assets. I believe that for the Betfury team, adding this feature was essentially an experiment, an attempt to expand the Betfury ecosystem beyond just gambling.
It is possible related to legal issues too as loan but it is only one of many possible reasons. Beyond legal issue, if BetFury saw that running the loan product on their gambling site is not profitable while it brings more tasks for their developers and staffs, with risk of security breach and exploitation, closing this product is a wise decision.
Only focus on gambling products is quite enough for an online casino and any other products can be considered as their trial products which can be closed anytime based on their internal data on operational cost and benefit as well as recommendation from compliance team.
While it was a good initiative by Betfury to introduce Betfury, it may not be that easy for them to run this loan business along with gambling. We do not know if it was a legal issue or maybe it wasn't that fruitful. Also, I think that giving loans also involves the risk of loans getting defaulted and the people not returning the loans if proper collateral is not collected.
If they had continued this, it would have given them a boost and stood out among the gambling industry as no other site offers this, but then there must be a valid reason to close this service.
