Do all casinos require Australians to register? Can’t I just deposit and play?

Unfortunately, currently, the Pay n Play option is only available for certain Scandinavian countries via Trustly services. However, Aussies can count on certain anonymous gambling with bitcoin destinations, including MegaWins.

As we said already, offshore casinos  let you gamble in bitcoin – the most anonymous method of transferring money online. More examples could be   mBit Casino and BitStarz.
For live dealer game players, however, these aren’t really anonymous. You’ll need to enter your name and last name before being able to access the tables in real money mode.
