There different ways to earn without investing here in the crypto community. But for me, it is so hard to join different bounties most especially if you are just a newbie. You need to rank up first. But there are times that ranking is not a requirement when joining other bounty campaigns such as Twitter Campaign because all you have to provide is your account with a number of followers. If you have courage and patience, then I am sure you can find any ways to earn here in crypto.
