Probably a lot of young people or those that live in countries where 100$ means the difference between poor and middle class.
As for me, no way I could rely on the forum for income.
Lately, as in the last year with the kid growing up, with the wife away for a week every month, I never managed to get to the 50 posts per week mark.
Also, I've stopped being that active during weekends, haven't yet found a deal that would be better than playing with my kid in the park.
I'm in the best-paying campaign (99% sure??) but even so, at current prices, it would be 1/3 of my wage and...that doesn't include health benefits, unemployment insurance, and private pension contribution.
If I were to add those on top of the wage I would probably have to manage 5-6 altcoins campaigns, post my full quota and do some
bounty hunting wasting time

I'm comfortable with the extra income that allows me to spend around some coins on various offers with touching my stash.
Some sort of allowance money.
