It is sure that bounty is always offering us the opportunity to make some additional income, but it is also obvious that it is harder nowadays to make money with bounty hunting as a few years ago.

There is no way they give you free money by doing nothing. If you already knew it very well, why you still joined in one of those campaign? Just move to btc paid campaign which much more safer than altcoin bounty
