Apparently, somewhere in 2019, they've stated they had MGA (Malta Gaming Authority) license. On the other hand, MGA says following:
MGA has officially announced that it has no connection with bcgame, as bcgame had previously announced. I found this page on their official website:
The Malta Gaming Authority (MGA) is hereby declaring that it has no connection with bc.game. Any reference to the MGA and/or gaming licence/s said to be issued by the Maltese Authority, as stated by bc.game, are false and misleading.
I also looked for where bcgame might have made this claim and found nothing, including no discussion on any forums or mention of it on any news sites.
I don't think bcgame can be held accountable for this, given that the statement is outdated and dates back to 2019. Even if it did, bcgame could be considered to have overlooked the error and officially sought a license from Curacao.
