Delegate to someone (or a bot) that can use your delegated SP to make you more money. They do get the curation rewards, but those are minimal. If you can get a $0.50 vote or more for 50SP, it's totally worth it. minnowsupport and its trail usually bring $2.30 or so.... so your delegation is well worth it.
