Navigating the world of cryptocurrency can be both exciting and overwhelming, especially when it comes to managing your digital assets securely and efficiently. Whether you're new to crypto or looking to refine your knowledge, understanding key processes—from buying and selling digital currencies to securing your account—is essential. This comprehensive guide answers the most frequently asked questions from users, offering clear, step-by-step insights into critical functions on modern crypto platforms.
How to Buy and Sell Cryptocurrency with a Third Party
One of the most common ways to trade digital assets is through peer-to-peer (P2P) or third-party transactions. These allow users to buy or sell cryptocurrencies directly using various payment methods like bank transfers, e-wallets, or even gift cards.
To initiate a transaction:
- Navigate to the P2P trading section of your platform.
- Select the cryptocurrency you wish to buy or sell.
- Choose a reputable third-party seller or buyer with high ratings.
- Agree on the price and payment method.
- Complete the transaction following the platform’s escrow process for security.
Always verify the counterparty's history and avoid external communication that bypasses the platform’s protection mechanisms.

Why Can’t I Join a Campaign?
Many users encounter issues when trying to participate in promotional campaigns or bonus programs. Common reasons include:
- Not meeting eligibility criteria such as geographic restrictions.
- Failing to complete required identity verification (KYC).
- Using multiple accounts, which violates most platform policies.
- Missing deadlines or not fulfilling minimum deposit/trading requirements.
If you're unable to join a campaign, review the official terms and conditions carefully. Ensure your account is fully verified and complies with all stated rules.
How to Find Your Deposit Address and Tag/Memo/Comment
Accurate deposit information is crucial to avoid losing funds. When depositing cryptocurrencies, especially tokens like XRP, XEM, or EOS, you must include both the deposit address and a tag/memo/comment if required.
Steps to locate this information:
- Go to the "Deposit" section in your wallet.
- Select the specific cryptocurrency.
- Copy the unique deposit address provided.
- If prompted, copy the corresponding tag/memo—it’s often labeled clearly beneath the address.
⚠️ Warning: Sending funds without the correct memo can result in irreversible loss. Always double-check before confirming any transaction.
Using a Physical Security Key to Protect Your Account
A physical security key (like YubiKey) adds a powerful layer of protection beyond SMS or app-based two-factor authentication (2FA). It prevents phishing attacks and unauthorized access even if your password is compromised.
To set it up:
- Access your account’s security settings.
- Choose “Add Security Key” under 2FA options.
- Insert your physical key when prompted and follow on-screen instructions.
- Register backup methods in case the key is lost.
This hardware-based authentication aligns with FIDO2 standards and is one of the most secure ways to safeguard your crypto holdings.
Understanding the Referral Program
Crypto platforms often offer referral programs that reward users for inviting friends. You earn bonuses based on your referrals’ trading activity, while new users may receive incentives like fee discounts or welcome bonuses.
Key features:
- Unique referral links automatically generated in your dashboard.
- Transparent tracking of invited users and earned rewards.
- Rewards typically paid in cryptocurrency after certain conditions are met.
Participating responsibly helps grow your network and unlock additional earning potential.

How to Link an Authenticator App
Using an authenticator app (such as Google Authenticator or Authy) enhances account security compared to SMS-based codes.
Setup process:
- Download an authenticator app on your smartphone.
- In your account settings, select “Authenticator App” under 2FA.
- Scan the QR code displayed on-screen with your app.
- Enter the generated six-digit code to confirm linking.
Store recovery codes securely—losing access to your authenticator without backups could lock you out permanently.
New User Bonus Program: Terms and Conditions
Welcome bonuses incentivize new users to begin trading. However, these offers come with specific rules:
- Minimum deposit amounts may apply.
- Trading volume requirements must be fulfilled before withdrawing rewards.
- Bonuses often expire after a set period.
- Only one bonus per user or household is allowed.
Always read the fine print before claiming any offer to avoid surprises later.
Creating a Passkey (App-Based)
Passkeys are the next evolution in secure login technology—passwordless, phishing-resistant credentials stored on your device.
To create one:
- Go to your account’s security settings.
- Select “Create Passkey.”
- Confirm via biometrics (fingerprint or face recognition).
- The passkey is automatically saved and synced across your trusted devices.
Unlike passwords, passkeys cannot be guessed or stolen via fake websites, making them ideal for long-term security.
Depositing Bitcoin (BTC) Using OKX Lightning Network
The Lightning Network enables near-instant, low-cost Bitcoin transactions by operating as a second-layer solution on top of the main blockchain.
To deposit BTC via Lightning:
- Select “Deposit” in your BTC wallet.
- Choose “Lightning Network” as the transfer method.
- Scan the QR code or paste the invoice link.
- Confirm the payment in your Lightning-compatible wallet.
This method is perfect for small, fast transfers without high miner fees.
Adding an OKX Widget to Your Home Screen
For quick access to balances, markets, or trading tools, adding a mobile widget streamlines your experience.
Steps (iOS/Android):
- Long-press on your phone’s home screen.
- Tap “Widgets” or swipe right to the widget menu.
- Find the OKX app and select the desired widget size.
- Drag it to your preferred location.
Now you can monitor prices or manage assets without opening the full app.
I Haven’t Received the SMS Code
Missing SMS codes can delay logins or transactions. Possible causes include:
- Poor cellular signal or carrier delays.
- Blocked numbers—ensure short codes aren’t filtered.
- Temporary system issues on the provider’s end.
- Incorrect phone number on file.
Try resending the code after a few minutes or switch to an authenticator app for more reliable delivery.
How to Verify an Individual Account
Identity verification (KYC) is mandatory for most advanced platform features, including withdrawals and higher trading limits.
Process overview:
- Go to “Verification” in your profile.
- Select “Individual” verification type.
- Upload clear photos of your ID (passport, driver’s license, etc.).
- Complete a live selfie or facial recognition check.
- Wait for review—usually takes minutes to hours.
Once approved, you gain access to enhanced functionality and improved security clearance.
