#BTCBackto100K Cryptocurrencies, like Bitcoin and Ethereum, are digital assets that use cryptography for secure transactions. They're decentralized, meaning no government or institution controls them. Transactions are recorded on a public ledger called a blockchain. Cryptocurrencies offer anonymity, speed, and low transaction fees. However, they're highly volatile, and their value can fluctuate rapidly. As a relatively new market, cryptocurrency investing carries risks, but it also presents potential opportunities for growth and innovation. It's essential to educate yourself and exercise caution before investing.
