Wonder if anyone can suggest site/sites to look for bounty campaigns?
Look into Alternate cryptocurrencies > Marketplace (Altcoins) > Bounties. You'll a lot of bounties there. But if you want, you can participate on medichain.
There are many bounties launching every day but the problem is choosing is very difficult today, because some companies are scamming the people after they raise some amount of money without paying anything to the people. So we have to be very careful in choosing a bounty.
