Popular cryptocurrencies: Dogecoin, Bitcoin, Ethereum, Bitcoin Cash, NEO and others.

Cryptocurrencies are digital currencies. They are created using digital cryptography to process transactions and create new “coins.” Cryptocurrencies like Bitcoin are popular because they are decentralized. In other words, banks and governments don’t control access to the currency. In contrast, fiat currencies are more easily manipulated by governments and banks.

There are thousands of Bitcoin alternatives called altcoins. Cryptocurrencies like Ethereum and Ripple have improved upon Bitcoin’s original model or created differences in their currencies to support niche uses. Fiat currency is money that a government has declared to be legal tender. The term altcoin is sometimes used to refer to non-Bitcoin cryptocurrencies.

If you’ve heard of cryptocurrency, chances are you’ve also heard the term “blockchain,” since its technology is what makes cryptocurrencies unique and valuable.In simplest terms, blockchain is a method of storing all Bitcoin transactions in a ledger that’s attached to each and every coin. From a digital perspective, blockchain is literally a chain of programmatic blocks.

Each block lists transaction details like dates, times, amounts, and traders involved. All of the blocks together are called a chain, which functions like a publicly-accessible, if encrypted, database. Blockchain gives structure to the Bitcoin ledger. The ledger is encoded by cryptography so that its contents are insulated from hackers and can be copied to any computer.

The use of cryptography also makes it very difficult to forge coins.

Cryptocurrencies may be appropriate for traders who are looking for a high-risk, potentially high-reward trading instrument

Bitcoin (BTC) is the cryptocurrency that started it all and it remains the gold standard for a cryptocurrency. It can now be used to buy goods and services electronically — and can also be used as a way to pay for goods in foreign currency while avoiding transaction fees. Bitcoin is by far the most popular cryptocurrency and many crypto traders choose to start trading crypto with it.

Dash (DASH) was created to fix perceived flaws in the Bitcoin concept – specifically anonymity protection and transaction speed. Originally called xcoin, then darkcoin, Dash can confirm a transaction in seconds and has workarounds to prevent double-spending. Dash also mixes the transactions of multiple users using coinjoin which helps to anonymize them.
