Are they phishings or BC game mirrors?
In the world of gambling domain phishing is rife in imitation, they always target famous gambling sites, anyone remains aware of suspicious domains, Usually phishing domains often look wrong words, they often add characters and so on, my advice.
In order to avoid fraud or phishing access to the BC.Game site, it will be done through an official link and check the BC.Game URL carefully or thoroughly.
As far as I know there are some phishing domains about BC.Game that I know.
Example:
BC-Game [.] Com (pay attention to the connecting mark), BCGame-Official [.] Com (additional "Official" on the domain), BCGame [.] Net (different domain extension), BCGame [.] Org (different domain extension).
So once again, do research carefully when opening the BC.Game site.
