#TradingTypes101 Cryptocurrency, or crypto, is a digital or virtual currency secured by cryptography. Unlike traditional money, crypto doesn’t rely on banks or governments. Instead, it uses decentralized technology called blockchain—a secure, shared ledger that records transactions across many computers. Popular examples include Bitcoin and Ethereum. Crypto can be used for buying goods, investing, or transferring funds, all without intermediaries. It offers privacy, faster transactions, and lower fees, but it’s also volatile and faces regulatory challenges. Understanding crypto means exploring how blockchain ensures trust and transparency, while also acknowledging the risks, potential rewards, and evolving impact on global finance.
