BTC and lightning are being worked on right now. As a new startup, it's wise to go a niche area first before proving the MVP. If we had BTC from the beginning when our software wasn't as much as now, we would've provided a bad user experience. Now we're confident to bring in big boys.
Just for information - it is not allowed to have a thread on gambling section if a platform does not support Bitcoin as a payment method. I think no one informed you that which is why the thread is in this section. Usually the moderators move the thread to the altcoins section if they find any platform in this section that does not support Bitcoin as a payment method.
It is good to know that Basepoker is already working on implementing Bitcoin deposits. It would be even better if they added the Lightning network, too. I have only used the Lightning channel a few times in my life. Not many platforms accept the Lightning channel. I am sure people will love that.
