Sincerely it is very easy to pay wages with altcoin since those that will collect it are already involve with cryoto. For instance I do engage in some online task in which I get paid through altcoin. (Note the task is personal). But paying salary with altcoin will a little bit hard due to d fact that not everybody van access internet not to talk of aving wallet
