I just use dicing sites. Earn a little bit from giveaways and then cash in! I was up to 4 bitcoin at one point, but now I'm back on the faucet. I don't ever autobet and never bet if I see someone winning a lot (since the site might adjust odds as it pays out).
Signature campaigns are interesting, but I don't really like the idea of touting someone else's website, it's very spammy. Youtube probably makes more sense as you can be a content creator instead.
