1. What is Bitcoin?
Bitcoin is the world’s first digital currency, created in 2009. Unlike traditional money (FIAT currencies), Bitcoin is not controlled by any government or central bank. Instead, it is managed by a network of users using blockchain technology. Bitcoin is designed to be fast, secure, and global.
While central banks can print new money at any time, Bitcoin has a fixed supply – there will never be more than 21 million Bitcoins in existence. This is what keeps Bitcoin’s value.
Bitcoin was created in 2009 as a response to the 2008 financial crisis. It was created by an anonymous person or group known as Satoshi Nakamoto, who published a document (so-called White Paper) describing the principles of Bitcoin. This document brought the revolutionary idea of a decentralized digital currency.
The first Bitcoin transaction took place in 2010, when a programmer bought two pizzas for 10,000 BTC. Today, these Bitcoins would be worth billions of crowns.
- Security: Transactions are transparent and cannot be changed.
- Decentralization: Bitcoin works without intermediaries, directly between users.
- Speed: Transactions via Bitcoin are faster, especially for international payments.
- Low fees: You save on fees compared to bank transfers.
3. Bitcoin wallets
A Bitcoin or crypto wallet is a digital tool that allows users to store, manage, and transact with cryptocurrencies. It essentially functions as the equivalent of a regular wallet you carry in your pocket, but instead of physical notes and coins, you store digital cryptocurrency funds. There are different types of cryptocurrency wallets, the main ones being hardware and software wallets.
Hardware wallets (Cold wallets): These wallets are physical devices designed specifically for storing cryptocurrencies offline. They most often resemble USB flash drives or other small devices. The keys and data are stored offline, which means they are less susceptible to hacking or malware attacks. Examples of hardware wallets include Trezor and Ledger.
Software wallets (Hot wallets): These wallets are software installed on a computer or mobile device and allow users to store and manage their cryptocurrency funds. They can be either online (connected to the internet) or offline (without an internet connection). Software wallets are generally more vulnerable to attacks such as malware, phishing, and hacking. Examples of software wallets include Exodus, Electrum, Coinbase Wallet, Trust Wallet, etc.
Hardware wallets are significantly more secure than software wallets because they store private keys offline on a physical device, which reduces the risk of hacking and malware attacks, among other things.
Cryptocurrency wallet security is a key aspect when storing and managing your cryptocurrency assets. Here are some important things to keep in mind:
Private key: Make sure your private key is always safe and secret. Never share it with anyone, and don’t store it in unsecured places like email or public cloud storage.
Physical security: If you use a hardware wallet, make sure it is physically protected from theft, damage, or loss. It should be stored in a safe place, such as a safe or other secure storage.
Software updates: Regularly update your wallet software to get the latest security and bug fixes. Most hardware wallet manufacturers provide regular firmware updates that improve security and functionality.
Two-factor authentication: Use two-factor authentication (2FA) wherever possible, especially with online software wallets and exchanges. This increases the protection of your account from unauthorized access.
Phishing and malware protection: Be wary of phishing attacks and malware that may be aimed at obtaining your private keys or login details. Always verify the address of the website where you enter your information and use antivirus software with current updates.
These measures can maximize the security of your cryptocurrency assets and minimize the risk of loss or theft.
