There are a lot of bounty campaign to choose from. It is a good way to start earning while also learning at the same time. You only need a few minute of your time to spend to be able to earn.
People are too impatient nowadays to receive their bounty rewards, some of the ICO extends their crowdsale for some reason maybe they need more time to collect money or they just need to extend the ICO so they can have more time to develop their technology. If the ICO extended it doesn't mean its a scam, just be patient and join bounty campaign that you think is legit.
