A cryptocurrency is recorded on a blockchain: a shared digital ledger copied across thousands of computers. Every transaction is added to it and can't easily be altered.
There is no central bank issuing it and no single authority that can reverse a payment.
Crypto can move 10% or more in a single day. That volatility attracts traders, but it means position size matters more here than almost anywhere else.
Most people buy crypto through centralized exchanges that hold the coins on their behalf. It is convenient, like a bank account, but you rely on the exchange's security and solvency.
If the exchange fails or is hacked, your assets can be at risk.
Decentralized exchanges let you trade directly from your own wallet without handing your coins to anyone. You keep full control, and full responsibility.
There is no support desk if you send funds to the wrong address or lose access.
Many crypto losses come from security mistakes, not price moves.
You now know the four major markets and what makes each one different.
