joining a bounty campaign is my side job and is useful for leisure time. before working in the bounty campaign I already had a professional job as a security. to fulfill my daily needs I always rely on salaries from security guards. I cannot rely on salaries from bounties as the main income. because the payment from the bounty is uncertain. but sometimes there are also many salaries from bounty when the ICO project that I follow is successful.
If you hit the jackpot from good bounties, the earnings is much higher than your monthly salaries, sometimes it worth a year of pay out,
there's people who really get lucky following bounties and needs not to work anymore for some years as the payments/ rewards that they
have gained is enough to invest to a business.
