Crypto for Dummies: why it's not magic, but just math

Let's try to figure it out without fancy words. Cryptocurrency is just money that doesn't live in a bank, but on the internet. No paper, no coins. Instead, everything is recorded on the blockchain - imagine a huge online ledger where every transaction is recorded. And the coolest part: no one can erase or forge it.

Why is this even necessary?

The main idea is simple: you send money directly to a person without intermediaries. No bank, no transfer fees, no three-day delays. Money goes straight from your wallet to someone else's. Like Venmo, but works worldwide and no one can block it.

Main features of crypto:

Decentralization — the system operates on thousands of computers simultaneously. There is no single boss like a Central Bank that can break everything or freeze an account.

Transparency — any transaction can be verified. All data is open, but remains anonymous.

Freedom of movement — money moves without borders and restrictions. Want to send crypto abroad — no questions asked.

Scarcity — most cryptocurrencies have a hard cap on issuance. For example, there will never be more than 21 million bitcoins. This makes them as rare as gold.

The most famous example is Bitcoin

He is the first and most successful. BTC works completely independently: without the government, without banks, without anyone. You completely control your money. The government cannot freeze it, the bank cannot cancel the transaction. It is yours, and only yours.

Here is the essence: crypto is a way to be your own bank.
