Crypto use cases

Many people first think cryptocurrencies exist only to replace cash and bank balances. That idea is partly true but far too small. Crypto technology also changes how software, money, and ownership work. Blockchains make rules for networks and reward the computers and people who follow those rules with protocol coins. Those coins act like fuel for the network and a reward for validators and miners. Some networks use their native coin to pay fees for every action, so users must hold a little of that coin to interact with apps. Other tokens live inside apps and have special jobs. These utility tokens let you pay for services, buy in-app items, earn access, or vote on decisions for a platform. Decentralized exchanges use native tokens to reward people who provide liquidity, and attention-based systems reward users with tokens for watching or engaging with content. Finance on blockchain, often called decentralized finance, offers lending, borrowing, and automated markets without a bank in the middle. Stablecoins were created to tame the wild swings of most tokens by linking value to something steady so people and businesses can send and hold value without constant fear of sudden changes. There are also non-fungible tokens, which are unique digital items that cannot be swapped one-for-one. NFTs let artists prove ownership of digital art, let gamers own rare items, and let people tokenize pieces of property or music rights. Tokens can also represent real-world assets in a tamper-proof way so ownership moves with transparency on a ledger. Beyond coins and tokens, crypto builds new social contracts and governance models where holders can vote on upgrades and rules, and communities can fund projects through tokenized incentives. The technology also enables programmable money that reacts to conditions or conditions future payouts, which opens new business models. The whole ecosystem stitches together apps, money, identity, and ownership into a web that does not rely on a single company or bank. This makes Web3 more than a payment system. It makes a platform for new kinds of digital cooperation and trade. If you imagine crypto as a toolkit rather than only as a coin, you see how many jobs it can do: currency, reward, governance, identity badge, ticket, scarce digital art, and a bridge between digital and physical value. Each use moves power from central gatekeepers to communities, and that is the true utility at the heart of crypto.
