Kalkulator Bitcoin v Južnokorejski von — tečaj v živo

Bitcoin has a fixed supply: there will never be more than 21 million BTC, and every ~4 years the "halving" cuts the miner reward in half. That programmed scarcity is why many treat it as digital gold rather than a coin for everyday spending.

The network is secured by proof of work (mining): thousands of machines compete to validate a block every ~10 minutes. It is the most computationally backed blockchain, which makes it very hard to attack, at the cost of high energy use and low throughput versus newer chains.

In Europe, BTC is used mainly as a long-term store of value and a diversification asset, not as an everyday means of payment. For small, frequent amounts the Lightning network enables near-instant payments, but adoption is still limited.
