Yes, there are a lot of ways for you to earn money without shelling out of buying at first. You can join and participate on some bounty campaigns, you can do Facebook, Twitter, YouTube, Reddit, Telegram and even in this forum, Bitcointalk. You can complete some marketing tasks like posting or creating blogs, vlogs and others. You do not need to invest money first but then you still need to invest time and effort into it. You will be paid in token once the project ends and those tokens can be converted into coins of your choice. You can use those coins for investments or cash them out to get the money you want.
