yes of course. in 2018, we can see huge number of members are participating to the bounty campaigns. it is a huge increase. so i think near future bounties will be no longer profitable. as a example bountyhive of colorlessK. you can see the number of participation at a glance. more than 15,000 20,000 members are register on it. so i dont think each member will earn at least 50$-100$
