It is my first time to hear about DraftKings. When I visit the article and read about DraftKings, they have 5 methods to deposit but in the withdraw, I only see it's only 2 method which is Paypal and Check. They don't use bitcoin as deposit and withdraw so I think if they can add bitcoin as the payment, it will attract more visitor to come. And when I visit on the DraftKings website, I see they have big prizes and I am sure they attract more gamblers to play.
I have recently read through wikipedia article related to them that draftkings was established since 2012 and they are trustable daily fantasy sports which available for almost all of kind sports such as football, NBA, tennis or MMA and we never heard about them before because draftkings was not available to crypto users because as you says they only accept paypal and check as part of their service
