Hi slavadp1,
This email is not from Bitsler it's just a scam.
We will never ask you for your BTC address, when we are running some promotions, all the prizes are sent on the players accounts on Bitsler.
We are not spaming our players emails, we only use them to answer to the players support tickets. We are thinking about a news letter in the future but it's only a project. Please ignore any other email you can get. If you have any doubts, feel free to contact our support.
Regards,
Gabriel
News letter is a good idea for informing people on upcoming promotions but also at the same time you have forum for that. But I think since people get lied very often because of these spam emails, it will be better to make popup on bitsler. Regular players will always see when they login, so their will be less mistakes from their side about email becuse they will know bitsler never send them email. But still, I like your idea, will be glad if you consider my suggestion too.
