It's a good sign but, as always with cryptocurrency, this will not fully take off until we have price stability.
Imagine you get your salary in Bitcoin equivalent one day and the next day it drops by 10% because some news came out or something...people could lose their homes with such volatility.
This is the reason why the switch to Bitcoin salaries will be a gradual process. E.g. the Japanese
company that already pays employees in BTC only pays a certain percentage (10 % or something
like this) in BTC and the rest in Japanese Yen.
No one is suggesting that companies switch 100 % of the salary payments to BTC, at the beginning
it will only be a fraction until BTC is more mature. Of course some pioneers like freelancers
that work independently will switch to 100 % Bitcoin much faster, but traditional companies
will have to be more conservative.
