Bounty is one of the lowest paid jobs in the crypto industry. Some companies can still pay $ 100 - $ 300 for signature or creating content. If you want to increase your income, I recommend learning how to do more complex work for companies.
Of course, a bounty campaign is the least paid job because to participate in a campaign, you don't need complicated requirements, and you need to put your opinion in, then you get paid, easy work = low wages.
