Oh, and as far as what you can make ... you are very unlikely to make a significant hourly wage. For instance on CryptoNinja.co we don't have ads. I realize this hurts the bottom line, but it makes for a better user experience, faster load times, and these things lead to higher search engine rankings. That's the game, SEO. We were also very fortunate to have launched just a couple weeks after Coinpot. That has really been our bread and butter. The airdrop space is very crowded but that also allows us to have a smaller "giveaways" page that includes contests and bounties and other things besides airdrops. It's been less than a year, and I don't want to talk about exact numbers, but these are the top clicks:

That pays for the domain, hosting and SSL.
