Bounties are still worth it for investing time to time but you have to be more careful as a large percentage of them are surprisingly just a scam and will only collect your details for marketing purpose. But I cam assure that there are still some ICO that gives a passive income, one to be noted is the Dencoin token which ensure you to have a good and quality kind of making profit with them. Check on it and find out that it was good and reliable.
