"Welcome to steemit platform, my friend note that, Users with huge amounts of Steem Power are called whales. A single vote on your content by a whale can add hundreds of dollars to your payout. Whales can calibrate the power of their votes now, so not all whale votes confer huge rewards anymore.
Users with a medium amount of Steem Power are called dolphins. One of their votes can add a few cents or a dollar to your payout.
Users with a small amount of Steem Power are called minnows. These users’ votes may add less than a cent to your payout. You will start out as a minnow unless you invest significant amounts of bitcoin into Steem Power (don’t risk anything you can’t afford to lose).
Don’t worry about these categories. Being a minnow doesn’t mean you’re doomed to fail. It just means you need to put something of value into the system, be that content curation, content creation, investment or something else."
