Practical guide: keeping privacy in a encrypted world

INITIALLY, ENCRYPTED MONEY WAS BORN IN PURSUIT OF PRIVACY AND FREEDOM, BUT NOW EVERYTHING IS BEING TRACKED, LINKED AND SOLD. THE BLOCK CHAIN IS A PERMANENT PUBLIC ACCOUNT, THE EXCHANGE REQUESTS IDENTITY INFORMATION (KYC) AND THE ANALYSING COMPANY EARNS MILLIONS OF PROFITS BY LINKING YOUR WALLET TO REAL IDENTITY。

the good news is that as long as conscious measures are taken, you can still remain largely private. you don't have to become a complete &ldquao; you wear a tin hat & rdquao; you just have to develop some basic habits. the following are truly effective privacy protection techniques for 2025:

1. Stop using wallet addresses

Every time you use the same address to receive funds, you actually reveal your trade history to the world. As a result, a new address is created each time it is used, or at least different addresses are generated for different relationships (e.g. one for wage income, one for transactions, one for DeFi, one for entertainment). Today, most quality wallets support the automatic creation of a new address — — make sure you have the functionality。

2. To separate your identity from that of your former spouse and use different wallets for different parts of life:

• One“ public ” walletFor connecting Twitter/Discord (the wallet is expected to eventually be exposed)

• One“ important asset ” cold wallet, never connect to the Internet or decentrize applications (dApp)

• One or two& ldquo; routine ” hot walletFor trading or DeFi, supplementing funds only when needed

RememberNever make direct transfers on the chainI don't know. If funds have to be transferred, either an exchange without KYC (without identification) or Monero (Menroco) can be used as a bridge。

3. AVOIDING THE USE OF KYC EXCHANGES WHERE PRIVACY IS REQUIRED

If you complete the KYC on the Binance, Coinbase and Kraken exchanges, the wallet will always be bound by your real name. These exchanges are used only as a conduit for money/money in French currency and are transferred to private wallets as soon as the transaction is completed, while ensuring that assets are not transferred back to the same address。

The better choices for 2025 are:

• BisqI don't knowHavenoI don't knowLocalMonero(Put it when it's still working)
• NoonesI don't knowHodl HodlI don't knowPeach Bitcoin(For bitcoin)
• SimpleSwapI don't knowChangeNOWI don't knowFixed Float(NO EXCHANGE TOOL FOR KYC REQUIRED)。

4. Use Monero for real privacy transactions

Bitcoin is not private, nor is the Ether. But Monero can do that (by signing rings, hiding addresses and RingCT technology). If you need to cut the chain link between the sender and the recipient, the asset can be replaced with an XMR and the transaction can be converted back. Yes, costs are sometimes high and liquidity is not perfect, but it is still the most effective option compared to other options。

Bitcoin privacy: correct use of CoinJoin

Ensure the correct use of CoinJoin technology when using bitcoin. For example, using a Wasabi wallet combined with CoinJoin or JoanMarket. As a result of the related arrests in 2024, the Whirlpool function of Samourai's wallet has ceased and is now almost the main tool for the protection of Bitcoin privacy. It is suggested to mix currencies after consolidating UTXO or purchasing bitcoin. Do not only carry out small commingling operations — — suggest multiple rounds to ensure privacy。

6. INHERITANCE PRIVACY: USING PRIVACY L2 OR BLENDING INSTRUMENTS (PRUDENCE)

Tornado Cash is still subject to United States sanctions and is at risk of being used in the area. The following are better options:

• RailgunSupport for privacy balances on the Ether, Arbitrum, Polygon and BSC
• Aztec(A) FULL PRIVACY SOLUTION ON THE "L2" FORMULA
• Nightfall: Polygon's privacy chain is still in operation。

IF THE PRIVACY REQUIREMENTS ARE EXTREMELY HIGH, IT IS RECOMMENDED THAT THE NEW WALLET + VPN BE USED FOR EACH TRANSACTION AND THAT THE WALLET BE DESTROYED AFTER THE ROUND。

7. Always use quality VPN or Tor

YOUR IP ADDRESS WILL LEAK EVERYTHING。Never without itVPN_Other OrganiserI DON'T KNOW. A VPN SERVICE THAT IS RECOMMENDED FOR PAYMENT AND YOU CAN CONTROL THE KEY, FOR EXAMPLEMulvadI don't knowIVPNandProtonI don't know. Avoiding the use of free VPNs and of well-known but log-recording services (e.g. Express, Nord, Surfshark, all of which were found to be false). If you have very high privacy requirements, you can choose Tor plus Bridges or i2p, but it needs to be noted that these methods are very slow in trading。

8. Access to browsers is more important than you think

• Create a separate browser profile for encrypted currency operations (or simply use a separate browser)
• UseBraveorFirefoxand installuBlock OriginandClearURLsPlugins
• DisableWebRTCFunctions
• Do not enter Google, Discord or Twitter in the same browser configuration file
• Use a temporary container (recommended Multi-Account Contractors plugin for Firefox, as a deity)。

Use hardware wallets where possible + isolation operations

Recommended use of hardware walletsLetgerI don't knowTrezorI don't knowKeystoneorGridPlus LatticeI don't know. Offline signing of transactionsNever enter your symgraphy on any websiteI don't know. If a website asks you to provide a private key or a note, there is no doubt that this is a fraud。

Don't show off on social media

Really, don't show off. Issuance of portfolio screenshots, ENS names or NFT displays, each of which is the data point of the chain analysis company. For example, when you push & ldquao with a real name; you just bought $50 ETH; you're exposed。

additional additions to — — privacy technologies emerging in 2025:

• "Stealth Addresses" is about to land on the Ether Housemaster(ERC-5564 AND ERC-6538): START USING WALLETS THAT SUPPORT THESE STANDARDS, WHICH WILL SIGNIFICANTLY ENHANCE PRIVACY。
• PayJoin (P2EP): Even without CoinJoin, it makes chain surveillance more difficult。

You do not have to fully comply with all recommendations to achieve privacy protection. Just do it right#1 (stop using wallet addresses)I don't know#2 (separate identity)I don't know#3 (avoided)KYCExchange)and#7 (UseVPNorTorI'm not sureAnd that's 90 percent of the privacy goal。

remember, “ perfect is the good enemy ” from the base, with increased proficiency, more levels of privacy protection are gradually added。
