That is the start from them. There is much more in this act from them. Samsung is a giant company and they are putting most of their potential in creating this hardware for bitcoin. It means that they believe in bitcoin and as this giant company is in trust on bitcoin then people will also trust that yes bitcoin is the coin which has a bright future.
Just think why a bigger company will create something for bitcoin if they will not believe on it. They believe on its future that is why they are planning for it.
It's probably more a case of they support profits and understand that they could be in at a nice level to sell these chips as more people come on board to bitcoin, it would be nice to think that they believe in bitcoin and what it is but until they start accepting bitcoin as a method of payment I will believe that it's money over power.
