What is cryptocurrency and how does it work?

What is cryptocurrency? A cryptocurrency is a digital-only token. It uses cryptography (hence the shortened name, "crypto") to regulate how the tokens are created, how they're traded, and how secure they are. And (here's the key appeal for many) it doesn't use or need a central bank or government to control or manage them.

What is a crypto coin?

These crypto coins have their own blockchains which use proof of work mining or proof of stake in some form. They are listed with the largest coin by market capitalization first and then in descending order.

Is crypto a secure currency?

“The best-known crypto, Bitcoin, is a secure, decentralized currency that has become a store of value like gold ,” says David Zeiler, a cryptocurrency expert at financial news site Money Morning. “Some people even refer to it as ‘digital gold.’” Using crypto to make purchases securely depends on what you’re trying to buy.

How are cryptocurrency transactions recorded?

Transactions are recorded in “blocks” that are then linked together on a “chain” of previous cryptocurrency transactions. “Imagine a book where you write down everything you spend money on each day,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax.
