Its hard to decipher which bounty campiagn can make you rich. There are many factors that are invloved for a bounty to provide good money. Team, bounty allocation, uniqueness of the project , listing price and off course period the bounty token will be distributed
right, even though the project reaches hardcap it still doesn't guarantee if it will make bounty hunters get rich because at the moment it's hard for new projects to have high coin prices.
plus now most projects really drop in value after the list so we really can't say what projects can really make us rich.
If you participate in the bounty campaigns in 2017, you are very rich at this time because at that time there were still very few people doing bounty and low competition rate, making many people earn a lot of money. Now when everyone knws the bounty campaigns then get tokens is getting less and very few good projects for you to work with.
