If you have to ask you probably want to be paid in fiat and put your surplus into bitcoin. Otherwise you might have to worry about tax implications of spending bitcoin for daily expenses etc.

Depends if they pay you directly or it goes through some broker or insitution (kyced coins). For privacy, it's better to buy non-kyc I think.

I would say yes, IF:

• IF you think the value of bitcoin will go up
• IF they are guaranteeing a certain amount of bitcoin
• IF you think the future value will be worth the work

For an easy example, let say bitcoin is currently $50k. If your salary is $50k, and they agree to pay you 1 bitcoin (not $50k worth of bitcoin) for 10 years, I would take that deal because you are possibly getting $100k+/year in the future.

If the deal is "We'll pay you $50k worth of bitcoin", I don't really see the point.

i guess that depends
are you paying tax over the wage in btc?
where you buying your bitcoin?
If you are using an exchange you are loosing fees along the way. Direct onchain transaction to your wallet will save you fees i guess
