Typically, campaigns that pay money for a signature have very strict conditions. Not the fact that you can fulfill them.
If the reward is high, then I think that it's worth trying your hand at it.
Surely, your current campaign pays you in tokens? If there will be better conditions in Fiat, will you change the signature?
My signature campaign makes payment in btc and tokens. To date, this is more than enough and fair in my opinion. Fiat scam, everyone knows this. I have not yet met the bounty compaign with payment in fiat. But, if this happens, then I will surely pass by
