What are cryptocurrencies?

Cryptocurrencies are digital or virtual currencies built on a technology called blockchain. A blockchain is a decentralized network that ensures all transactions are secure and transparent. Unlike traditional currencies like the Swedish krona or the U.S. dollar, cryptocurrencies are not governed by a central bank. Bitcoin, launched in 2009, was the first cryptocurrency and remains the most well-known​​. You can read more about Bitcoin in our article What is Bitcoin?.

How do cryptocurrencies work?

Most cryptocurrencies are based on blockchain technology, which is a distributed database where transactions are stored in blocks. Each blockchain is secured through advanced cryptography, making all transactions visible and unchangeable once they are added to the chain. This process creates a high degree of transparency and security.
Transactions on a blockchain are verified by computers in a network, called nodes. For a transaction to be added to the blockchain, it must be approved by the network, which often involves a process, such as mining, where computers solve complex mathematical problems.

What is the price of cryptocurrencies?

The price of cryptocurrencies like Bitcoin and Ethereum fluctuates based on demand, supply, and market trends. Prices can shift quickly due to market volatility, making it essential to follow live prices if you plan to buy cryptocurrency. You can stay updated on Bitcoin’s price through platforms like BT.CX, where you can also buy and sell Bitcoin in real time.

Why choose bitcoin?

Bitcoin (BTC) was the first cryptocurrency and has become a symbol for the entire crypto market. Bitcoin’s long history makes it an attractive choice for investors seeking a reliable, long-term investment. Unlike many other cryptocurrencies, Bitcoin has a fixed maximum supply of 21 million coins. This contributes to Bitcoin's value-preserving properties and makes it usable as a hedge against inflation.
