Crypto Wallets Explained
A wallet doesn’t hold coins — it holds the keys that control them. Understanding the types is how you pick one that fits your needs without gambling with security.
Two questions define every wallet
First: is it hot (connected to the internet) or cold (offline)? Second: is it custodial (someone else holds the keys) or non-custodial (you do)?
Figure. There’s no single “best” wallet — match the tool to the amount and how often you’ll use it. Many people use both: a hot wallet for spending, cold storage for savings.
| Custodial | Non-custodial | |
|---|---|---|
| Who holds keys | The company | You |
| Convenience | Higher (password resets) | You’re responsible for backups |
| Control | Can be frozen/limited | Fully yours |
The HODL Guide view
For anything beyond small spending money, aim for a non-custodial, cold setup. A hardware wallet is the sweet spot of security and usability. Module 7 walks through securing one.
Key takeaways
- Hot = connected/convenient; cold = offline/secure.
- Non-custodial means you hold the keys — the goal for real ownership.
- Use hot for spending, cold for savings.
