Of course, fintech companies operating business in the jurisdiction of Nevada still need to get their respective and appropriate business permits. No law can be made exempting any legal entity (even charitable ones) from obtaining the required permits.
The state is just giving more benefits to these companies so that maybe they can be encouraged to base their operations in the said location. Actually, this is already a good start for these companies and I am sure that the fintech industry would be happy about it. Different places right now are competing for business so it would be good for other states to also lay down on the table what they can offer. We are hoping that other states can be encouraged to follow the lead of Nevada.
Right now, there is no denying that blockchain technology created an unstoppable buzz everywhere even in countries located in Africa. years from now, we could see this strong movement metamorphosed into something great...one that is really helping many people as we are battling so many evils and inequalities in our society (though don't get me wrong as blockchain is not the panacea we are looking for but a big revolution in itself).
