Yes, I certainly still believe in bounty and crypto-currencies, but every day participation in bounty campaigns becomes more and more difficult because of the influx of a large number of new participants, respectively, the rewards are reduced proportionally. But still, you need to look and then you can find good options.
Bounties campaigns are specially good for those people who do not have enough investment for trading. They can earn bitcoin there by joining and working for the projects without having any investment. But it is a fact that now it has become too much difficult to choose the right place for your investment.
