I saw this news yesterday, but I saw no public acceptance of crypto currency in there. It was only made clear that the said EcoWatt is now recognised and could be used as salary payment in the company as agreed, as long as it's acceptable by both the employer and the employee.
Regardless, it is still a good initiative to begin with. It is true that in able for the employees and its employees to start this kind of transaction it needed a mutual decision to begin with. Once some company started doing this (if ever there's no one yet) it will be just time to start that domino effect.
