A curated list of crypto, investing, security, research, and website tools that can help you learn, compare, and make better decisions.

Crypto exchanges can be useful for buying, selling, converting, and transferring digital assets. However, exchanges also carry custody risk, platform risk, regulatory risk, withdrawal risk, and product-specific risk. Keep your use simple, understand the product before using it, and avoid advanced tools until you know exactly how they work.

Exchange safety checklist

• Use strong two-factor authentication with an authenticator app.
• Keep only funds needed for active use on exchanges.
• Test withdrawals with small amounts before moving larger funds.
• Bookmark official domains and avoid sponsored search-result links.
• Read product terms before using staking, lending, margin, or advanced tools.
• Do not use money needed for essentials.

Important exchange risk note

Crypto exchanges are not the same as banks. Platform failures, withdrawal delays, regulatory restrictions, account limitations, phishing attacks, and market volatility can affect users. Advanced products such as leverage, margin, derivatives, structured products, lending, and exchange yield products can be especially risky and are not suitable for beginners.

Crypto Cards

Crypto cards can help some users spend or access digital assets in everyday situations, but they should be researched carefully. Fees, supported countries, identity verification, asset conversion, card limits, ATM rules, and custody arrangements can all affect the user experience.

Crypto card safety checklist

• Check whether the card is available in your country before signing up.
• Read the fee schedule before topping up, spending, or withdrawing.
• Understand whether crypto is converted before or during payment.
• Check supported assets, spending limits, ATM limits, and withdrawal rules.
• Do not keep more funds on a card app than you need for planned use.
• Use strong account security and avoid links from random messages or ads.

Important crypto card note

A crypto card is not the same as a bank account, savings account, or investment product. Users should understand custody, conversion, fees, country restrictions, identity verification, card limits, and what happens if the provider changes terms or pauses services. This resource is included for education and comparison, not as financial advice.

Wallets

Wallets help you interact with crypto networks and manage self-custody. Self-custody gives more control, but it also creates more responsibility. If a seed phrase is lost, exposed, or entered into a fake website, funds may be impossible to recover.

Tangem

Hardware wallet Card-based Self-custody

A card-based hardware wallet option for users who want a phone-friendly self-custody setup. Before buying, understand how backups work, how recovery is handled, and what happens if a card is lost or damaged.

Wallet safety reminder

• Never share your seed phrase.

• For card-based wallets, understand the backup process before moving meaningful funds.
• Do not buy hardware wallets from random resellers or unverified links.
• Use a separate wallet for testing new protocols.
• Review token approvals regularly.
• Do not sign transactions you do not understand.
• When in doubt, slow down before clicking.
