2. Decentralization: Bitcoin is not controlled by any central authority, such as a government or a bank. Instead, how to buy bitcoin it's maintained by a network of participants (miners) who validate and record transactions on the blockchain.

3. Limited Supply: There will only ever be 21 million Bitcoins in existence. This scarcity is programmed into the Bitcoin protocol and helps prevent inflation.

4. Mining: Bitcoin mining involves using powerful computers to solve complex mathematical problems. Miners compete to solve these problems, and the first one to do so gets to add a new block of transactions to the blockchain and is rewarded with newly minted Bitcoins.

5. Security: Transactions on the Bitcoin network are secure due to the cryptographic nature of the blockchain. Once a transaction is confirmed and added to the blockchain, it's extremely difficult to alter.

6. Anonymity: While Bitcoin transactions are recorded on the public blockchain, users' identities are not directly tied to their transactions. However, all transactions are visible on the blockchain, making it pseudo-anonymous rather than fully private.

7. Volatility: The value of Bitcoin can be highly volatile, leading to significant price fluctuations over short periods. This volatility is one of the reasons some people view Bitcoin as a speculative investment.

9. Wallets: Bitcoin is stored in digital wallets. These wallets can be software-based (online, desktop, or mobile) or hardware wallets (physical devices). They hold the private keys needed to access and manage your Bitcoin holdings.

10. Global Accessibility: Bitcoin can be bought, sold, and used by anyone with an internet connection, making it accessible to people around the world.

Remember that investing in Bitcoin carries risks due to its price volatility and the evolving regulatory landscape. If you're considering buying Bitcoin, make sure to do thorough research and consider your risk tolerance before making any investment decisions.
