It depends on them and there's a reason why the minimum withdrawal is 500 chips. Maybe some modification could be done if they see that there's a demand for it.
That demand will need a lot more weight before it can be looked into and put forth for consideration.
They know about that and even without demand as long as they consider the price of Bitcoin as quite high, it could be done. But who knows if they will soon.
On the freerolls, are chips bought to be used or it is provided on the platform?
I use PokerNow more often, but the two platforms are way different from each other, that's why my questions are coming this way.
You don't need to have chips if it's a free roll. You only have to register for you to participate. There are daily free rolls that you can enjoy. You still got some chips, right? there are some small prizes you can add if you win 1st-3rd place.
