Cryptocurrency is a digital or virtual currency that operates on distributed ledger technology called a blockchain and uses cryptography for security. It is decentralized and operates independently of a central bank.
Unlike traditional currencies, cryptocurrencies are not backed by a physical commodity or government, and their value is determined by market demand and supply. Cryptocurrencies can be used to buy goods and services, transfer funds, and trade in markets. Popular cryptocurrencies include Bitcoin, Ethereum, Litecoin, Ripple, and Cronos.
Many cryptocurrencies, like Bitcoin, are created through a process called mining, which involves solving complex mathematical equations to validate and record transactions on a blockchain. This mechanism is also called Proof of Work (PoW). Another consensus mechanism that has increased in popularity — as it is more energy efficient — is Proof of Stake (PoS). Instead of mining, PoS relies on network participants validating transactions. Ethereum, the second-largest cryptocurrency, uses this consensus mechanism.

There are several ways to buy cryptocurrencies, including:

1. Brokerage services: Crypto brokers allow users to simply buy and sell cryptocurrencies. A popular example is the Crypto.com App, trusted by over 100 million users. It is available at the Apple Store and on Google Play.
2. Cryptocurrency exchanges: These are online platforms where users can buy, sell, and trade cryptocurrencies using fiat currency or other cryptocurrencies. They offer more complex functions compared to a crypto brokerage, adding trading instruments like crypto derivatives.
3. Peer-to-peer (P2P) marketplaces: These are platforms where buyers and sellers can directly trade cryptocurrencies without the involvement of a third-party exchange. This is also known as DeFi, short for decentralized finance. Multiple P2P crypto marketplaces can be accessed all in one app via the Crypto.com DeFi Wallet.

It is important to perform proper research and choose a reputable platform to buy cryptocurrencies. For instance, Crypto.com holds the highest security rating in the industry. In addition, it is advisable to store cryptocurrencies securely in a wallet like the Crypto.com App or Crypto.com DeFi Wallet.

To buy crypto, follow these general steps:
