Bitcoin as a salary will be way to risky and most employees will not accept it. The price is way too volatile and if it crashes people will lose their money a day. I don't think that the people will take the risk. People will definitely not trust bitcoin as it seems so complicated to all the newcomers.
To newcomers or new to bitcoin, it will look very risky and complicated. But I think for those who are already used to receiving bitcoins, it will be different. It is quite a risk to take all your salary in bitcoin, but I think if you get half in bitcoin and half in fiat, the risk is minimized. And some of us can live with that.
Nothing beats experience of course, we are here for a long time already and I can say that we are matured enough to understand the risk of bitcoin and only risk we can see is the price volatility but for me that would be fine as I am a gambler by nature.
