Key Points
- In 2021 alone, approximately $14 billion worth of cryptocurrency was pilfered, not accounting for losses due to user errors in previous years or the exchange failures witnessed in 2022.
- This guide will delve into the fundamentals of secure crypto storage, explore various wallet types, and address frequently asked questions.
Evaluation of Storage Options: Pros, Cons, and Risks
Several methods exist for storing cryptocurrency, each accompanied by considerations of risk, usability, and security. It’s essential to categorize wallets into custodial/non-custodial and hot/cold types before discussing specific wallet options.
- Custodial Wallets: Managed by a third party, these wallets involve the third party holding private keys. On the other hand, self-custody wallets provide users complete ownership of their keys.
- Hot Wallets: Conveniently accessible online, these wallets enable easy fund access. In contrast, cold wallets store funds offline in cold storage for enhanced security.
All the following wallets fall into each one of these categories.
Exchange Wallets
When purchasing cryptocurrency on an exchange, the funds automatically go to your exchange wallet. This custodial hot wallet hosted by the exchange holds your private keys.
- Pros: Convenient, supports a wide array of assets.
- Cons: Limited control over private keys, vulnerable to hacks.
Additional Example:
Binance Wallet: Binance, one of the largest cryptocurrency exchanges, provides an exchange wallet for users upon registration. It allows convenient trading of various cryptocurrencies but comes with the trade-off of limited control over private keys.
Hardware Wallets
Hardware wallets provide a secure way to store private keys in cold storage, making them inaccessible to hackers. These wallets can be brought online to execute transactions. The signing of a transaction occurs on the physical hardware device itself, separate from a user’s personal computer, adding an extra layer of security.
Pros: High degree of security.
Cons: Could be confusing for less technical users, and the average cost is around $100.
Additional Examples:
Ledger Nano S: A popular hardware wallet known for its security features and ease of use.
Trezor Model T: Another reputable hardware wallet with a touch screen for enhanced user interaction.
Mobile Wallets
A mobile wallet is a hot wallet held on your smartphone. These wallets are usually self-custodial. Mobile wallets are convenient for sending or paying with crypto. However, they may be less secure than cold wallets and are not advised for storing large balances.
Additional Examples:
Trust Wallet: A popular mobile wallet supporting a wide range of cryptocurrencies.
Coinbase Wallet: Known for its user-friendly interface, suitable for beginners in the crypto space.
Pros: Quick and easy to use, good for transactions.
Cons: Potential for loss of funds if not properly secured, backed up, or if the seed phrase is compromised.
Paper Wallets
Before the advent of hardware wallets, paper wallets were the sole cold storage option in the early days of crypto. A paper wallet can be created by printing out a private and public key. Once funds are sent to the public key, they are taken offline and can only be accessed by sweeping the private key into a hot wallet. There is a substantial risk of user error or wallet damage with paper wallets, and they are not frequently used anymore.
Pros: Provides an affordable cold storage option.
Cons: High risk of user error or wallet damage.
Additional Examples:
WalletGenerator.net: An online tool for creating paper wallets for various cryptocurrencies.
Bitcoin Paper Wallet: A simple and straightforward tool specifically for creating Bitcoin paper wallets.
Recommendations for Secure Cryptocurrency Storage
The optimal method for storing crypto varies based on individual circumstances. Considerations include the amount invested, transaction frequency, and technical expertise:
- Investment Amount: Higher amounts warrant stringent security measures.
- Transaction Frequency: Frequent transactions may justify some compromise on security for ease of access.
- Technical Expertise: Less technical users might prefer user-friendly options.
While a self-custody cold storage wallet, such as a hardware or paper wallet, is deemed the safest, it might not suit everyone. Small crypto holdings may suffice in an exchange wallet, balancing ease of use with security. Non-custodial wallets offer both usability and security, as users retain control over their keys.
For substantial holdings, prioritizing security by storing the majority in cold storage (hardware wallet) and a smaller portion in a hot wallet for quick transactions is advisable.
Managing Multiple Wallets
Experienced users often manage multiple wallets for different purposes, such as long-term cold storage, day-to-day transactions, and niche trading.
Conclusion: The Right Approach Depends on You
In conclusion, the best crypto storage method depends on individual needs. Striking a balance between hot and cold wallets can offer optimal security and usability. Always create backups and familiarize yourself with your chosen wallet to minimize the risk of user error.
