I have a question OP, hope you could answer this. So I was thinking about the definition of what makes a "DeFi", aren't all crypto coins is "DeFi"?

Some coins like BNB is a utility coin for an exchange which make it directly related to finance, but what about Steem that is used to reward it's users by creating blogs, it is still decentralized and it is used for payments but the difference is that it's not directly working in the finance industry.
