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
It seems to me that the whole problem of remuneration with the help of the crypto currency is that it is necessary to constantly evaluate the work at the rate of the coin. Crypto currency is always unstable in its price and therefore every time fluctuations will be quite significant in your salary.
