As we grow more, we hope to do some Bitcointalk campaign soon. I don't think we're quite ready yet especially when BTC is missing. We're adding BTC soon and researching how to do lightning payment. I'll keep yall updated!
It's quite surprising to me you haven't added Bitcoin payment yet when you've already added Bitcoin Cash and other altcoins. This is really something you are missing, and some gamblers often use Bitcoin payment. There is a reason why gamblers like Bitcoin too much: because when a pump happens, their portfolio also gets up. So you are losing such gamblers on your platform. It's been a while since you launched your announcement thread here but haven't focused on Bitcoin payment.
However, we hope as soon as possible we will see the Bitcoin logo on your site. Besides that, you will do something to draw attention from forum gamblers, like promotional offers including bonuses. Even though you are quite older here, unfortunately, due to a lack of branding, many potential gamblers haven't noticed your platform yet. Hope you will focus on branding as well to draw attention from the forum gamblers also.
