I Have Zero Knowledge About Crypto – Where Should I Start?

Hey Reddit, I’m starting from absolute zero in cryptocurrency and blockchain. I don’t understand the difference between Bitcoin, Ethereum, or other coins, how wallets work, what DeFi is, or how NFTs fit into the picture. I want to learn the basics, understand how the ecosystem works, and know how to stay safe from scams. Can anyone recommend beginner-friendly guides, courses, YouTube channels, or communities where I can ask questions and gradually build my knowledge?
