I think the "no fees" policy is going to be the thing that is going to draw a lot of people. I do not know how they going to keep that up.. but it is definitely a good "bait" to draw people to this casino. 
What I have previously found with other casinos that tried this, was that they would start with the "no fees" policy and later when they have pulled a lot of gambler... suddenly apply a strict withdrawal limit to qualify for this "no fees" withdrawal.
I don't think they are planning on changing the "No fees" policy in the future based on their previous replies in this thread and based on the fact that they have been operating from a long time and aren't a newly opened casino.What I have previously found with other casinos that tried this, was that they would start with the "no fees" policy and later when they have pulled a lot of gambler... suddenly apply a strict withdrawal limit to qualify for this "no fees" withdrawal.
Several crypto gambling sites like Sportsbet, Bitcasino etc have been offering similar benefits from a long time which is why it is a feasible long-term option.
