Indeed until now the bounties was not profitable, maybe only if the bull run will come the bounties will be profitable, but until then maybe the bounty hunters start to trade, and try to make a profit there.
I think bounty is always profitable that is not profitable when you participate in a bounty project. In a bearish market I am still able to get $ 1000 per month, but it must be a real project not a scam. So the bounty will be profitable if you don't follow the scammer project
