What is Cryptocurrency

Cryptocurrency is a digital or virtual currency secured by cryptography and does not exist in physical forms like U.S. Dollars or other fiat currencies. Cryptocurrencies are supported by an underlying technology called blockchain, which acts as a decentralized digital ledger.


Every cryptocurrency transaction is recorded in the blockchain and becomes immutable once confirmed and validated. This means transactions can neither be reversed nor tampered with.


Institutional investment in cryptocurrencies is growing, a testament to the potential and future of digital currencies. Investing in cryptocurrencies allows you to enter the world of decentralized finance and invest in a frontier technology that is rapidly gaining popularity.

What can I do after I buy crypto?

Fiat currency transactions are maintained on a centralized ledger inaccessible to the public. By contrast, crypto transactions are on a public blockchain that can be tracked by anyone. Thanks to the consensus mechanism, everyone can validate the transactions and add them to the blockchain, making cryptocurrencies decentralized.


One thing to note is that, unlike fiat currencies, cryptocurrencies aren't controlled or issued by central authorities. It makes them more transparent and less susceptible to government interference or corruption. Additionally, cryptocurrencies are more speculative and volatile, meaning trading cryptos could yield lucrative returns.


Bitcoin and Ethereum are the two largest cryptocurrencies by market capitalization. If you are looking for a hassle-free way to buy popular cryptos like Bitcoin and Ethereum, OKX is your go-to place.
