I wouldn't like to receive my salary in bitcoin because receiving your salary in an unstable currency sounds kinda risky.
I wouldn't like it to have parts of my salary lost if I'm unlucky i'd rather just invest fiat manually into bitcoin.
That's a right decision, investing fiat in bitcoin can be profitable in long run but we cannot afford to put our monthly income at risk by accepting salary in bitcoins as price may fall in coming years.
but this is also possible that bitcoin price won't fall and it increase. even I think chance of price increase is higher then price fall.. and bitcoin is unpredictable. we can't see about coming years. bitcoin is good and it is the best thing.
