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.
 
On the other hand, this could also be a step up for any firm in Dubai that wants to start paying their workers with crypto currency; it could easily be recognised and approved, just like the EcoWatt token, which appears to be a native token for a particular industrial use.
