It is not favorable for the project having that kind of payment, but you lose the chance of gaining more profit out of that coin. what if that coin or token gets higher price than what you get paid. Besides, it is part of the promotional activities of a project so therefore no point of having it promoted but nobody patronizing it, no community supporting it. If ETH will be the price, those hunters run or vanish after getting paid, you cannot ask for support, they are only after the price. So it is not favorable.
