The volatility of cryptocurrencies is one side of the payroll, but you still have to change part of your payroll to fiat, and this is the loss on commissions too.
Losses on commissions are small when there is no strong growth or fall of 2-3% at good exchange points. It takes a few minutes to create an application and pay, then you just need to wait until the transaction has 2-3 confirmations, and the money from the exchange office will automatically come to the selected payment system.
I think that in the future theyll still figure out how to pay salaries in cryptocurrency so that we dont lose when the market falls, maybe there will be some kind of exchanger or something else
