Here are some more key facts 1. Limited Supply: Many cryptocurrencies, like Bitcoin, have a capped supply. Bitcoin, for instance, is limited to 21 million coins, contributing to its scarcity and value over time . 2. Mining and Proof-of-Work: Bitcoin and some other cryptos use “mining” as a way to validate and record transactions, which requires solving complex computational problems (proof-of-work). Others, like Ethereum, have shifted to proof-of-stake, which is less energy-intensive.
