I don't read in the article that they are allowing Cryptocurrency in fact they have a crack down and restricting traditional online payment processor, there's still no guaranty that they will use Bitcoin, they are still in the process of creating a new laws about online gambling there might even be a crackdown like what happen to Paypal and the rest
Sooner or later, there will be a new online gambling casino that integrates their payment with the other online payment processor, and perhaps, they can consider using crypto to their site. But in fact, gamblers in that country will search for other ways to play gambling still, and I am sure they will get it later. It will not stop them from playing gambling if gambling is their way to having fun and using their free time, and I guess that they have an offline casino, which the government doesn't know where the place is.
Those places would exist if there would be high demand of gambling games on such place or country even though it would turn out to be against or illegal on what had been mandated by the government itself.
Stopping it totally would not really mean that they would really get rid of it knowing of that someone can play without the need of those typical fiat processor or any other third party and this is where
crypto gambling will really make up some buzz.The problem here is that the German government would declare another ban or prohibition towards cryptocurrencies?
