To choose good bounties to get involved in, you have to look at the project and see if:

1. it fits your needs for bounty-related aspects;
2. the project is good and will have success (for what matters to you as a bounty hunter, the fact that the new token will be listed on Exchanges).

If you want to have a look and get some information in a good Bounty campaign that has just started, I can suggest you RAWG.

They have just started a very rich bounty program for everyone who is willing to participate:

with a nice referral program that can double your rewards.

The ICO site is this one: RAWG. It's a video game discovery platform that converts your skills into goods and services.

You can earn tokens by playing your favorite games. The site is already working, with more than 50,000 games in the database and new games are getting added every day. This is the site: https://rawg.io/

Quite good looking, don't you think?

You can also join the airdrop here.

Have a look. I hope this information is helpful!
