That could be true but those who have been in the industry for a long time most likely are getting decent pays ($$$) unless they're nuts to love their job so getting such small fee is not a big deal
It is. I have heard a lot that people do almost anything for money, especially in countries like US. And there are way more websites than what is listed on the OP, accepting crypto. I mean who wouldn't accept crypto, its better than paypal, because of irreversible transactions. I even see streamers on twitch accepting crypto.
