Crypto or cryptocurrency is a digital asset that uses blockchain technology to record transactions transparently and securely. The most popular examples are Bitcoin and Ethereum. Crypto enables transactions without intermediaries like banks, so fees can be lower and processes faster. However, high price volatility makes it risky for investors. In addition to being a payment tool, crypto is also used in various ecosystems such as DeFi, NFT, and smart contracts. Therefore, it is important to understand the basics, risks, and strategies before diving into the world of cryptocurrency to make more informed investment decisions.
