The price moves
Bitcoin’s value can rise or fall after you buy.
GUIDE · BITCOIN IN SIMPLE WORDS
A practical beginner example — from creating an account to making your first small purchase.

In Book 1, Alex makes his first small bitcoin purchase. The book keeps the process general so the explanation can remain useful over time. Here, we follow one specific practical example as it works on Bybit EU today.
Bybit EU is not presented as the “best” or only option. It is one example of a European platform that helps us understand the basic steps. Buttons, payment methods, limits, and fees may change.
Follow the path from account access to seeing bitcoin in your balance.
Bitcoin’s value can rise or fall after you buy.
Card, transfer, and EUR balance can have different costs, times, and limits.
Review the rate, every disclosed charge, and the BTC credited.
You do not need one whole bitcoin. One BTC has 100,000,000 sats.
To create a new account, you can use the referral link below, which leads to the official Bybit EU domain (bybit.eu). Before entering personal details or a password, always check that you are on bybit.eu. Use accurate personal information, a unique password, and enable 2FA as soon as registration is complete.
This page contains a referral link to Bybit EU. If you sign up through the link, Bitcoin in Simple Words may receive a reward from Bybit EU, at no additional cost to you.
At the moment, Bybit EU states that both sides can receive a reward of up to €25 in BTC, subject to the current terms of the referral program.
After opening the registration page, the process is usually short. Exact buttons may change, but the basic flow remains similar.
Bybit EU may show different verification methods, such as Quick Verification, Bank Verification, or Video Verification. The available option and the exact steps may vary depending on your account and country.
After KYC, you can either add euros to Bybit EU first and use your available EUR balance, or choose an available payment method when making the purchase. The options shown may vary depending on your country, account, and service availability.
Choose EUR, enter the amount, and review the details of the available bank method before continuing.
Card, PayPal, or other options may appear. Always review any displayed fee and processing time.
If you have already deposited euros, you can use the available EUR balance without making a new deposit at that moment.
From the top menu on Bybit EU, open Buy Crypto and select One-Click Buy. This is where the simple fiat-to-crypto purchase flow begins. On the next screen, you will choose the fiat currency you are paying with, the crypto you want to receive, the amount, and an available payment method.
In the Spend field, choose EUR and in Receive select BTC. Then enter a small amount for your test purchase and check how much BTC is shown as the amount you will receive. The available payment method may vary depending on your account and country.
20 EUR demonstrates the process only and is not a recommended amount. The BTC shown depends on the current rate and fees.
Before confirming, make sure you can see all of the following:
Only after reviewing every detail should you confirm. Depending on the payment method, an additional approval or confirmation step may be required. Wait for a clear success or failure message. If the quote expires, review the new BTC and fees. Do not repeat the order in a hurry if you are unsure whether the first completed.
Open the Funding Account and select the Crypto tab. BTC will appear there as a separate asset together with the available balance and related actions. In the screenshot, the amounts are hidden using Bybit EU’s built-in privacy feature.
While bitcoin remains in your account, the platform manages the private keys. Self-custody means moving it to a personal wallet whose keys or seed phrase only you control. That is a separate step requiring preparation. Never withdraw to an address you have not checked.
One bitcoin is divided into 100,000,000 satoshis, or sats. You do not need one whole BTC. Example only: 0.0002 BTC equals 20,000 sats. This explains unit conversion, not what a specific EUR amount will buy.
You’ve made your first small bitcoin purchase, and it now appears in your Bybit EU account. The next step is to set up your own self-custody wallet, so you can receive bitcoin directly and control it yourself.
No. You can buy a small fraction within current limits.
Limits vary by method, country, and time. Check the purchase screen.
The price moves and the quote refreshes. Fees and payment method may also affect it.
Not necessarily. Fees, time, limits, and rate may differ.
A completed crypto purchase generally cannot be reversed. Review before confirming.
Platform custody and self-custody have different risks. On the platform, you do not control the private keys.
The interface and labels may change. Use this guide as a map and always check the official platform.
