First decide whether you need an online wallet, an offline wallet, or both. Then you can consider specific wallets.
Wallet types are mainly about security and convenience: online wallets are more suitable for daily use but aren’t very secure, while offline wallets are less convenient for frequent use yet are more secure.
What kind of wallet do I need?
Look for an online (aka “hot”) wallet that’s web-based and runs as an app on your phone or a program on your computer if:
- You only need to store a small amount of bitcoin, which wouldn’t be too painful to lose;
- You're looking for a good user experience;
- You can only afford a free wallet;
- You’re not concerned about privacy;
- You want web access to it from a mobile device or computer;
- You trust a third party to safeguard your wallet;
- You need to share the wallet with someone else.
Consider an offline (aka “cold”) wallet, for storage on a paper or hardware, if:
- You need to store a large amount of bitcoin and security is a top priority;
- You don’t need to use it often or access it anytime, anywhere;
- You prefer to safeguard your funds yourself rather than trust a third party;
- You’re ready to pay for hardware (typically from about 50 to a couple hundred dollars);
- Privacy is very important for you.
You can, however, use both types of wallets: a cold one for storing bitcoins, and a hot one for spending them.
How to evaluate a specific wallet
Ask these questions:
- Does it only support Bitcoin or can it store other cryptocurrencies as well?
- If it's a web wallet, does the address begin with HTTPS? That offers greater security than an HTTP wallet.
- How secure is authentication? Does it offer two-factor authentication (username and password plus some piece of information only you have)?
- Does it have a multi-signature feature (if you want to use a wallet with multiple owners)?
- Is the wallet “hierarchical deterministic” (HD), meaning it will always use a new Bitcoin address to receive payments and so enhance the security of your money?
- How transparent is the wallet provider? Do you know who they are?
- Has the company behind the wallet published the wallet's code and is it open source?
- Is the wallet simple to use?
- Is there a way to backup the wallet?
- What does the community have to say about the wallet? Check forums like Bitcoin Reddit or Bitcoin Forum.
- For a hardware wallet, what do you think about its design, user interface, manufacturer reputation, and price?
