Do not waste time with the bounty of new projects at the present time, it is difficult for them to successfully raise funds and pay for the bounty hunter. Try to participate in the bounty of the projects listed at the exchange, you will have a higher chance to receive tokens and can sell them.
Could you please share me any site or any link where i found some good bounties that is listed in exchange or tell me how can i find?
It's better for you to visit the service discussion of altcoin and you will find someone who has been creating a thread about which is the bounty that has already listed on the exchange site and which is not.
It will help you a lot.
