Bitcoins as a mode of payment is actually good but it should not be used to paid salaries .
BTC is already a mode of payment for some companies like Microsoft, Dell and sites like steam. Tge transaction speed would be needed to increase because the transaction fees they take and the time it takes to complete transmission of BTC is not proportional.
Being paid with bitcoin? That is really a great idea. Especially if your company or your job is technology-based or technology related, or even not, especially online jobs. It will be less hassle, I think, compared to other possible modes of payment. It will also help employees get more than the value they are actually should be getting, when price of bitcoin goes up.
I don't think that this is a good idea , poeple would have to be dependent on the value of BTC to buy something and would feel restricted.
