To create a mass trend of using bitcoin for salary payment, we need world class companies and corporations like Apple, Nvidia to join this movement. Small and unbranded companies cannot do this.
The CEO can do anything he wants to receive salary in any method in his company. Who care if Elon Musk receives his salary in Telsa company with Tesla products?
From what I can deduce from the article I feel this is an investment approach. Just like every company CEO decides how much the earn and how the get paid, it is not out of place for Remixpoint CEO to do same he deserves any method of payment he chooses.
The company workers who have to be governed by the CEO, and treated by the company are vulnerable to the company policy changes. We can not be sure that if all workers in a company are forced to receive salary in bitcoin, is it good for them.
The similar story is how El Salvador made Bitcoin Legal Tender in their nation years ago in the last market cycle, and forced all stores there must receive Bitcoin payments. Locals were not happy with that and you can imagine same unhappy feeling of workers who are forced to receive bitcoin.
We weren't told if the employees are to be paid in bitcoin as well. I don't think in a modern era as this employers will forces their employees to earn their salary using any currency outside their local fiat. The CEO of Remixpoint obviously doesn't depend on his salary for survival so this might be an investment approach in view.
Elsalvador case is a bit twisted because their is a case of country policy. In a country citizens have no choice but to accept what ever the government present to them as legal tender.
