Privacy
Privacy projects aim to reduce the transaction information exposed on a public ledger. Depending on the design, they may obscure senders, recipients, amounts or links between transactions.
How do privacy cryptocurrencies differ?
Browse the buying guidesSome apply privacy by default; others require an optional transaction type or a separate application. A privacy label does not mean every action, wallet or connection is private.
How it works
Privacy can rely on cryptographic proofs, concealed addresses or other mechanisms, each with different assumptions and usability tradeoffs. Information can still leak through exchanges, wallet behavior, network connections or later disclosure. Selective viewing features may help a user share records without publishing everything. Exchange availability and withdrawal support can differ by jurisdiction and change over time. Evaluate the protocol’s documented threat model rather than relying on a blanket claim of anonymity.

A little groundwork goes a long way
Before your next purchase or transfer, understand who controls access, where your crypto is going and what the trade will actually cost.
Protect access to your crypto
An exchange account and a self-custody wallet need different safeguards. Protect exchange logins with a unique password and strong two-factor authentication. For self-custody, your recovery backup is what lets you restore access.
Keep recovery words offline and private. A support agent or website asking for them is a reason to stop.
See a recovery example
Your phone breaks. An exchange may help you recover your account after identity checks. A self-custody wallet cannot reset your recovery phrase. Check your wallet’s official backup instructions before relying on it.
Choose the right transfer network
The asset, token version and network must be supported at the destination. A familiar ticker or a matching address format is not enough. Read the receiving platform’s deposit instructions before selecting a withdrawal network.
Check the address, any required memo or tag, fees and minimums. Consider a small test transfer first.
See a network example
Your destination accepts USDC on Ethereum. Selecting a cheaper network at the sending exchange does not make it an Ethereum transfer. Use a network both ends support; an ordinary withdrawal does not bridge tokens.
Understand the price you pay
Trading fees are only part of the cost. The spread, available liquidity and withdrawal charges also matter. A market order prioritizes execution; a limit order controls the price but may remain unfilled or fill only partly.
Check the order preview and the amount you will receive, then compare the full cost of your intended purchase and withdrawal.
Work through a cost example
Hypothetical example: a $200 trade with a 0.1% trading fee costs $0.20 in trading fees. A separate $5 withdrawal fee brings those charges to $5.20. Spread or slippage may add more; these are not quoted exchange rates.
