Just maybe, but I believe that if a person like the CEO you have mentioned is offering a bitcoin option for his salary/share, that means that he will make use of it. However, regular employees will likely just sell their bitcoin options to make a profit. I know a lot of people are already buying bitcoin, but it was not their intention to use it for buying as currency. The majority do this for the sake of investment strategy.
Maybe I'm wrong, but we're still far from realizing BTC as a global currency. But of course, we're going there.
You are wrong, because I don't even think bitcoin can become a global currency one day. Besides the barriers from governments, they will never agree to make bitcoin a global currency, even bitcoin investors like us don't want that to become a reality. The proof is that most people just see it as an investment, they try to accumulate as much as possible and hold on to get rich. No one wants to spend it. Therefore, the idea of bitcoin becoming a global currency is just a pipe dream that will never come true.
