What are the main sectors within the tech industry?

This question isn't about cryptocurrency, so it falls outside our crypto news focus. However, if you're asking about sectors within the blockchain and cryptocurrency industry, the main ones are: Bitcoin (digital currency), Ethereum (smart contract platform), DeFi (decentralized finance applications like lending and trading), NFTs (digital collectibles), mining (cryptocurrency creation), and exchanges (trading platforms). Each sector serves different purposes within the crypto ecosystem. If you have questions specifically about crypto sectors, trading strategies, or blockchain technology, we'd be happy to help clarify those topics.
