This is just a thought, but do some employers pay their employees in bitcoins? I'm not quite sure if this would be legal, but potentially this could be a thing of the future.
Yeah some people do pay their employees in bitcoin. Check bitwage. It is a bitcoin international wage payment system where the employers pays the employees in bitcoin. But different countries and states have different legal laws. I read it somewhere when paying the value of the bitcoin can never go below the minimum payment wages. But as long as the taxman gets their share nobody actually cares.
