There are people that are now willing to use bitcoin and the problem is the business that are still not ready to accept bitcoin. There will no mass adoption that will happen if those merchants are still focusing to use traditional payment system than the current payment system. Our economy will boost more if we will use cryptocurrencies, there are also a lot of advantages that they can get from accepting bitcoin and using it. There are just not aware so it is the reason why for them fiat is still the best way to use.
For now, the use of bitcoin are still remaining to be personal because of the lack of regulations and laws concerning it to be accepted widely by the masses and the large scale typical business on different countries. Because we can confirm it if they start to provide salaries in bitcoin and it is quite hard to implement if they will provide salaries without tax and literally, there's allot to adjust first for it to be implemented. I do really believe it will just take so long but in the future it possibly could really happen.
