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 like Bitcoin (BTC), Ethereum (ETH) and Polkadot (DOT) 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.

Unlike fiat currencies that rely on banks to maintain a centralized ledger inaccessible to the public, cryptocurrency transactions are on a public blockchain that can be tracked and monitored by anyone.

Additionally, depending on the consensus mechanism, anyone can validate transactions and add them to the blockchain, making cryptocurrencies decentralized.

Many believe that blockchain technology will shape the future of money, potentially rebuilding the global financial system from its foundations.

Moreover, institutional investment in cryptocurrencies is growing, a testament to the potential and future of digital currencies. Global world-leading companies like Samsung, BlackRock, Morgan Stanley, and Alphabet have invested in blockchain and crypto.

Trading cryptocurrencies allows you to enter the world of decentralized finance and participate in a frontier technology rapidly gaining popularity.

Users can buy popular cryptocurrencies like Tether (USDT), Polygon (MATIC) Dogecoin (DOGE) and more through a range of payment methods, including Apple Pay, Visa, Mastercard, MoonPay, and bank transfer.
