This is a very different use of the blockchain technology.
It really is very interesting to see a different real world use cases for crypto but in this case, I think they are using their own crypto to pay since the article on the OP stated that:
The site is using JOB cryptocurrency tokens to pay the bonus as well to convert the payment to the employee’s coveted currency. The company has elevated $50 million through its token offering in January.
After this, I think we are going to see more companies using blockchain technology in the future but I wonder though, will bitcoin still be the crypto king 10 years from now if many cryptos by that time exists?
