but are those CEOs actually using bitcoin in their lives or just accumulating for profit?
To be honest, it's not even a concern for us if they're using Bitcoin in their lives or they're for the profit. Who's not for the profit when they take BTC as salary or as an investment? Most of us do have this goal and the others won't even be worried whether we use it for real or not.
This type of people, those who take the step forward, will help bitcoin be adopted better. Soon, others might see the benefits of receiving your salary through bitcoin as Tashiro becomes a leading example.
They're doing an example for others to see that they're putting their money where their mouth is. And this is going to be a trend I guess in the next years to come. As they accumulate if ever the bear has come, they're doing the right thing. I'm not just sure about the taxation there but if it's said that it will include taxes, I wouldn't bother myself either.
