I am a graphic artist and as for me it is a payment like any other. However, it is more convenient because we avoid taxes, and as we know it is quite uncomfortable.
Not for long

and don't start telling people that you're taking bitcoins to avoid taxes.. You never know who's listening.
yes, i think its worth

...For example, if you get paid $ 500 in bitcoin, then $ 500 could be 1000 $ in the future, due to the rising bitcoin price on fiat money

Or it could be $250. You never know so don't be overly positive or it may bite you in the ass.
