I haven't yet read the acknowledgement. But I know people who already get their salary in bitcoin and other cryptocurrencies. And: why not? A few days ago I have written about companies paying bitcoin and other cryptocurrencies to their employees for example as business gifts or birthday gifts (https://steemit.com/deutsch/@taxguy/crypto-geschenke-und-deutsche-einkommensteuer-or-crypto-gifts-and-german-income-tax). We will see what the future may bring to us.
