Not a passive income,as it is requiring a lot of time and effort,passive for me woule be mining cryptocurrencies as the mining rigs will do the job and you will just need to wait for sometime so that you will be rewarded very well.Do not rely to these bounty campaigns as these wont give you stable income monthly,it is better if you are doing these bounty campaigns as side job so that you wont expect big to these bounty campaigns.
