If you had the option to get your salary being paid in cryptocurrencies would you choose that? If yes, which crypto would you opt for?

I don't think getting paid a salary based on cryptocurrency is a great idea. Cryptocurrency is too volatile and once you enter a work contract there would probably be no chance to renegotiate the terms of payment if the cryptocurrency value plunges until after the term of the work contract expires.

I guess maybe being paid for part time work on a day to day basis is fine. For example getting paid steem for an hour of writing. That seems like a better idea.
