Bitcoin Basics
Ways to acquire Bitcoin, what to compare between platforms, and steps before your first purchase.
Most people buy Bitcoin through a regulated exchange or brokerage that supports fiat deposits. Compare fees, supported payment methods, insurance or licensing, and whether you can withdraw to your own wallet when you are ready.
Before you buy, decide how much you can afford to hold for your time horizon, enable two-factor authentication on the account, and plan where coins will be stored after purchase. A small test withdrawal to your wallet confirms that your backup works.
Regulated exchanges and brokerages remain the most common on-ramps. Compare trading fees, deposit methods, withdrawal limits, insurance coverage, and whether the firm is licensed in your jurisdiction.
If you plan to hold long term, favor platforms that allow withdrawals to your own wallet without excessive friction. Some services optimize for trading frequency; others focus on simple accumulation.
Define an amount and time horizon you can stick with through volatility. Enable strong account security—unique password plus authenticator-based two-factor authentication at minimum.
Decide in advance where coins will live after purchase: on the platform for active trading, or in a personal wallet for savings. Mixing the two without a plan often leads to scattered balances.
Consider a small test withdrawal to a wallet you control. Confirm that your recovery phrase backup works before moving larger amounts. Save records of purchase date, amount, and price paid.
Review statements periodically and avoid leaving more on an exchange than you need for near-term activity. Many long-term holders treat exchanges as a temporary stop, not a vault.
