The bill was passed with an intention to open doors for new technologies in Arizona state. Two more amendments are still waiting in the senate of the State. One of them will prohibit restrictions in cryptocurrency mining in residences, another one addresses securities and crowdfunding. It should recognize the virtual coin as a digital representation of value and authorize its application as an exchange medium.
