Module 5: What is a Wallet?

Written by Old Glory Bank | Jun 6, 2026 4:00:00 AM

If cryptocurrency is digital money, then a crypto wallet is your secure way to access, manage, and protect that money.

Understanding wallets is one of the most important steps for beginners—it’s how you take control of your digital assets.

What Is a Crypto Wallet?

A crypto wallet is a tool that allows you to store, send, receive, and manage cryptocurrency.

Unlike a traditional wallet, it doesn’t actually “hold” your money. Instead, it stores the keys that prove your ownership of crypto on the blockchain:

Public key: Like an account number (you share this to receive funds)

Private key: Like a password (you must keep this secret to control your funds)

IMPORTANT: Whoever controls the private key controls the crypto.

Why Wallets Matter

Crypto wallets give you something powerful: financial ownership and independence.

With a wallet, you can:

  • Send money directly to others without intermediaries

  • Access your funds anytime, anywhere

  • Avoid relying entirely on third parties

  • Participate in the broader crypto ecosystem (trading, NFTs, decentralized apps, etc.)

Types of Crypto Wallets

There are two main categories of wallets: hot wallets and cold wallets. Within these, there are several types.

1. Hot Wallets (Connected to the Internet)

Hot wallets are online wallets that are easy to use and great for beginners.

Examples:

  • Mobile apps

  • Desktop software

  • Web-based wallets (browser)

Pros:

  • Convenient and fast

  • Easy to access and use

  • Ideal for everyday transactions

Cons:

  • More exposed to cyber risks because they are online

  • Best for small amounts and frequent use

 

2. Cold Wallets (Offline Storage)

Cold wallets store your keys offline, making them much more secure.

Examples:

  • Hardware wallets (physical devices, like a USB drive)

  • Paper wallets (printed keys)

Pros:

  • Highly secure from hacking

  • Ideal for long-term storage

Cons:

  • Less convenient and subject to loss

  • Requires more responsibility to manage
  • Best for long-term holdings and larger balances

 

3. Custodial vs. Non-Custodial Wallets

This distinction is especially important for beginners.

Custodial Wallets

A trusted institution holds your private keys for you, similar to how a bank holds your money.

Pros:

  • Easier to use

  • Account recovery options

  • Added security oversight

Tradeoff: You don’t have full control of your keys.

Non-Custodial Wallets, also known as Self-Custodial Wallets

You control your own private keys.

Pros

  • Full ownership and independence

  • No reliance on third parties

Tradeoff: If you lose your keys, you lose your crypto.

Security Matters: The Role of Trusted Institutions

While crypto empowers individuals, security remains critical, especially for beginners.

That’s where trusted financial institutions, like Old Glory Bank, play an important role.
