One day banks will accept Bitcoin as medium of exchange and accept deposits from bitcoiners. As soon as the world powers accept it as medium of exchange.
Where I live, if they accept Bitcoin as a good means of payment, then only under full tracking. They will also demand information about where I got this cryptocurrency, and ask for documentary justification. And now in the world there are only two ways to legally increase the share of Bitcoin in your wallet before the state, this is mining and trading.
But both methods have many aspects. And therefore the state where I live will never recognize income from signature campaigns as legal, and online casinos will not be an exception. It is easier to move to a normal country than to wait for improvements here.
