Although Bitcoin is a very profitable currency, its price fluctuates to a certain degree. It is unwise to pay all wages in Bitcoin.
Some countries do not accept Bitcoin as payment, so legal currency must be reserved to meet daily needs and other emergency expenses. Choosing to accept a small amount of Bitcoin for long-term holding and increase the number regularly will eventually get good returns.
Bitcoin is good for many but still we need some very long and good work for its primary use because currently we can't do this all in many countries it's not available and if available then we have some other factors as well as price change transaction speed its fees. Primary use is not easy because we have many peoples already try in this way, but it's not work for them, It's very hard and have many difficulties even you have legal framework but still right now it's not easy to live this as primary use case.
