> I would pay and get paid using monero

If you agreed to work for a company for X monero a month, and the value of monero (relative to USD or your local currency) dropped by 90% a few months later, would you continue to work at the originally agreed upon rate?

And on the opposite end, if a coffee shop sold lattes for Y monero, would you be okay with continuing to pay Y if monero shot up by 1000%?

Just because you get paid in crypto does not mean you do not hold the money in FIAT. Whatever people think about USDT or other stable coins, its easy to move your crypto worth into USD and back.

What you could do against the fact that the USD is heavily losing on value is a different topic tho.

On the same note: You are likely getting paid in $. Your currency lost about 4% in value against the CHF in the last months. Is this something you worry about? I guess not.

No, I'd raise the XMR price for my services. We still need fiat in order to pay for everyday things.

just do it relative to some low vol underlier

I mean we would probably pay and get paid in any currency that was stable enough in the world market and accepted by the people we want to buy from.
