DeFi

DeFi names the whole decentralized finance idea more than a single coin, and that makes it useful as a label but awkward as an item on its own. By our assessment, it points to lending, trading, and yield products that live on blockchains instead of inside a normal bank app. The upside is the plain one: open protocols, wallet-based access, and no central gatekeeper in the middle. The downside is just as plain, because the user has to deal with wallet security, gas fees, smart-contract risk, and a field that changes fast enough to feel messy. In practice it is a crowded corner of crypto with a lot of experimentation and a lot of noise, and the name can be broader than the thing in front of you. It sits closer to a sector tag than to a single currency, so the strongest use is as a shorthand for the DeFi world itself.
