You can buy cryptocurrency on exchanges: centralized (CEX) or decentralized (DEX).
CEX exchanges are managed by organizations that oversee all operations and provide maintenance and security. User tokens are stored in exchange wallets. There is a commission for trading. When registering, you need to confirm your phone number and email. To work, as a rule, you need to undergo KYC/verification: confirm your identity using a passport/international passport/driver’s license. Many of these exchanges provide the opportunity to buy tokens for fiat (rubles).
DEX exchanges work differently. Coins are exchanged for them without intermediaries. A commission is charged for the exchange. There is no need to register here; to use it you need to connect your wallet (click connect wallet and enter the wallet password). Coins will be transferred from wallet to wallet. For each transaction, the wallet will request permission to confirm the operation. DEX is more difficult to use.
