Thanks for the link, interesting reading. The company that Betsoft is licensed by is not and should not be responsible for auditing them, that should be done by an independent body.
But the licensor should be responsible to check if the Betsoft software is audited by an independent body, or not?
I do not know what the license requirements are in regards to a gaming software provider like Betsoft, but I know that the licensor has to proof the identity / addresses of the licensees. And if Betsoft has a rigged gaming software, you could sue the operator of Betsoft.
If nobody is regularly auditing them then why do reputable online casinos continue to host Betsoft slots knowing this, surely they ask for audit reports from their game providers or I would have thought so.
This would be a good question to the reputable casinos, why they use Betsoft. I know that many scammy and anonymous casinos use Betsoft scam gaming software, because Betsoft let them use their software anonymously.
When in doubt just choose games.bitcoin.com where all the games are provably fair and no need to register an account.
The best thing you can do nowadays, with all the scams in the height of USD million, is to register your gaming or betting account with Game Protect, because then you will have at least a consumer protection service included.
In most cases you can sue the responsibles, but players are sluggish and not really wiling to put some money on the table to enforce their claim and instread simply continue to lose $1000s or $10,000s.
