Bitcoin is a global peer-to-peer currency that has no central authority and a limited supply. It can be obtained through mining, exchanges, individuals, or selling goods/services. Bitcoins are stored in digital wallets consisting of public and private keys. While volatile, Bitcoin has the potential to become a mainstream currency if it gains a small percentage of the global payment market, which could drive the price per coin to nearly $15,000 by 2025. Security and risk of loss are important considerations for those interested in investing in Bitcoin.
