Crypto Basics
Crypto for Absolute Beginners: Bitcoin, Zcash, Monero & XLM
If words like Bitcoin, blockchain, wallets, private keys, exchanges and crypto addresses sound confusing, you're definitely not alone.
This guide is designed for someone who is just getting started. We'll look at four very different cryptocurrencies — Bitcoin (BTC), Zcash (ZEC), Monero (XMR), and Stellar (XLM) — and then walk through the basic process of getting started with a cryptocurrency exchange such as Kraken.
The goal is education, not a recommendation to buy anything. Cryptocurrency can be extremely volatile, and understanding what you're buying is more important than rushing into a purchase.
Start Here: A Beginner Crypto Video
If you're completely new to cryptocurrency, I recommend starting with a beginner-level explanation before trying to understand individual coins.
This video provides a beginner-friendly introduction to Bitcoin and explains concepts such as digital money, blockchain technology, nodes, miners, cryptography and custody.
Four Cryptocurrencies — Four Different Ideas
One of the biggest mistakes a newcomer can make is assuming that every cryptocurrency is simply "another Bitcoin."
These four projects have significantly different goals.
| Cryptocurrency | Symbol | Simple Explanation | Main Idea |
|---|---|---|---|
| Bitcoin | BTC | A decentralized digital monetary network with a limited supply. | Digital money, scarcity and decentralized value. |
| Zcash | ZEC | A cryptocurrency with Bitcoin-like characteristics and optional privacy features. | Digital money with shielded/private transaction capabilities. |
| Monero | XMR | A cryptocurrency designed specifically around financial privacy. | Private digital cash. |
| Stellar | XLM | A blockchain network designed for fast, inexpensive movement of money and digital assets. | Payments and financial transfers. |
Bitcoin (BTC)
Bitcoin is the original cryptocurrency and the one most people encounter first.
Its design emphasizes decentralization, a limited supply and the ability to transfer value without relying on a traditional central intermediary.
One important beginner concept is that you don't have to buy one whole Bitcoin. Bitcoin can be purchased in fractional amounts.
Zcash (ZEC)
Zcash is interesting because it combines a Bitcoin-like monetary design with optional privacy technology.
Zcash supports both transparent and shielded transactions. That means simply owning ZEC does not automatically mean that every transaction you make is private.
Wallet type, address type and how the transaction is conducted all matter.
Buying ZEC and using ZEC privately are two different things. If privacy is your goal, learn how shielded transactions and compatible wallets work before assuming that a transaction is private.
Monero (XMR)
Monero takes a different approach to privacy.
Privacy is a fundamental part of Monero's design rather than simply an optional feature.
Monero uses cryptographic technologies including stealth addresses, ring signatures and RingCT to provide transaction privacy.
Privacy-focused cryptocurrencies can have different exchange availability and regulatory considerations than other cryptocurrencies. Availability may also vary depending on your location.
Stellar (XLM)
Stellar is different from Bitcoin, Zcash and Monero in its primary focus.
The Stellar network was designed around moving digital assets and facilitating payments and financial transactions.
XLM is the native asset of the Stellar network and is used within the network for transactions and other functions.
A simple way to remember the four:
- BTC: decentralized digital money and scarce monetary asset
- ZEC: digital money with optional privacy
- XMR: privacy-focused digital cash
- XLM: payments and movement of digital assets
So How Do You Actually Buy Cryptocurrency?
A cryptocurrency exchange is one way for a beginner to purchase cryptocurrency.
Kraken provides educational material specifically aimed at people who are learning about cryptocurrency.
Kraken's learning center covers cryptocurrency basics, Bitcoin, wallets, buying crypto and other introductory subjects.
Setting Up Kraken: The Beginner Version
The exact screens can change as Kraken updates its application, but the basic process is straightforward.
Create an account through Kraken's official website or application.
Use a strong, unique password and enable available security features such as two-factor authentication.
Kraken may require identity verification before allowing certain services.
Follow the instructions presented by Kraken and provide the requested information.
Available funding methods vary by location and account.
Review Kraken's current options and choose a method you understand before depositing money.
According to Kraken's current mobile instructions, the basic process begins by tapping the + button and selecting Buy.
Select the cryptocurrency you want to purchase, such as BTC, ZEC, XMR or XLM, if that asset is currently available to you through Kraken in your location.
You don't necessarily need to purchase one entire coin.
Enter the dollar amount you want to spend or the cryptocurrency amount you want to purchase, depending on the available interface.
Before confirming, carefully check the cryptocurrency, amount, payment method, quoted price and applicable fees.
If everything looks correct, confirm the purchase.
Kraken maintains current instructions for buying, selling and converting cryptocurrency through its mobile application.
What About Crypto Wallets?
Eventually you'll encounter another important concept: self-custody.
You may hear the phrase:
This refers to controlling the private keys associated with your cryptocurrency rather than leaving the assets under the custody of an exchange.
Self-custody can give you greater control, but it also gives you greater responsibility.
If you lose a wallet's recovery phrase, or accidentally send cryptocurrency to the wrong address, recovery may be impossible.
Learn how wallets, recovery phrases and blockchain addresses work before moving significant amounts of cryptocurrency away from an exchange. There is no prize for making cryptocurrency complicated on day one.
Five Things Every New Crypto User Should Know
- Crypto prices can move dramatically. Cryptocurrency can gain or lose substantial value very quickly.
- Never give anyone your recovery phrase or private keys. Treat them like the keys to your bank vault.
- Double-check cryptocurrency addresses before sending. Blockchain transactions may be irreversible.
- Be extremely skeptical of guaranteed returns. Promises of guaranteed crypto profits are a major warning sign.
- Start by learning. A small educational purchase can teach you how an exchange works without immediately exposing a large amount of money to market risk.
A Simple Learning Path
If I were teaching someone who had never touched cryptocurrency before, I'd suggest this order:
- Watch a beginner cryptocurrency explanation.
- Learn the basic Bitcoin concept.
- Understand the difference between an exchange and a wallet.
- Learn how cryptocurrency addresses and transactions work.
- Set up an exchange account if you decide one is appropriate for you.
- Learn how a small purchase works.
- Study the differences between BTC, ZEC, XMR and XLM.
- Only then start thinking seriously about trading, investing or self-custody.
