Paying a dividend in a crypto currency is actually very difficult. Normally your broker just receives dollars and rolls them into your account or reinvests them.
You broker will have to send you instructions on how to make a wallet, then the company will have to validate how many shares you own and then transfer a proportional amount of digital currency to your wallet.

That is pretty complex. Even if understood, there are a lot of unanswered questions.
How is it taxed would be the primary one. What are legal precedents for imposing a tax structure?
