I have no experience being a witness, but i think it's a bit similar to mining in general.
Bitcoin mining is also not that profitable if you take everything into account, it's still a commodity business. The reason miners made a lot of money the last 5-10 years is because of rising prices. Let's say prices would stay always the same, the margins only would be very small. But if it's only about making money, then you could also just trade crypto.
In general mining is a very leveraged business, you can make a fortune in rising markets and lose everything in a crash. You see this also with gold miners for example. Let say that it cost 50 dollar to mine a gram of gold. If prices are 55 dollar they make 10% profit. But if the price is 60 dollar they make double the profit like before. While the price didn't increase that much.
