If you have liquid SBD, the basic Minnowbooster bot is great. @earthnation-bot is tiny but even more profitable and you're still eligible for it. If you prefer longer-term rewards with less work @steembasicincome is great if you expect to post every week for a long time.

If you have voting power, there are a lot of options for delegation and vote-selling and I haven't done good research on all of them. If that's something you're interested in you may have to do the research yourself.
