Doing bounties is my first option to make money using cryptocurrencies without any investments because it is really worth it if we got paid paid on it. There are factors that I considered everytime I join a bounty program like : the total amount of rewards allocated to the bounty, the percentage of the type I want to participate with from the total amount, the position of the bounty manager and the number of followers in their social media sites or the people they have in their community.
