Blockchain vs Cryptocurrency

Blockchain's most well-known use (and maybe most controversial) is in cryptocurrencies. Cryptocurrencies are digital currencies (or tokens), like Bitcoin, Ethereum or Litecoin, that can be used to buy goods and services. Just like a digital form of cash, crypto can be used to buy everything from your lunch to your next home. Unlike cash, crypto uses blockchain to act as both a public ledger and an enhanced cryptographic security system, so online transactions are always recorded and secured.

The term Bitcoin, for example, is used interchangeably to refer to both the blockchain and the cryptocurrency, but they remain as two separate entities. The very first blockchain application appeared in 2009 as Bitcoin, a crypto system using the distributed ledger technology. This also marked Bitcoin as the first "blockchain." The aspect of blockchain being used to house this new digital currency is what brought both entities into association, and what led them quickly into the spotlight. The Bitcoin blockchain describes only the technology in which the currency is housed, while the Bitcoin cryptocurrency describes only the currency itself.

HOW DOES CRYPTOCURRENCY WORK?
Cryptocurrencies are digital currencies that use blockchain technology to record and secure every transaction. A cryptocurrency (Bitcoin, for example) can be used as a digital form of cash to pay for everyday items as well as larger purchases, like cars and homes. It can be bought using one of several digital wallets or trading platforms, then digitally transferred upon purchase of an item, with the blockchain recording the transaction and the new owner. The appeal of cryptocurrencies is that everything is recorded in a public ledger and secured using cryptography, making an irrefutable, timestamped and secure record of every payment.
To date, there are more than 20,000 cryptocurrencies in the world that have a total market cap around $1 trillion, with Bitcoin holding a majority of the value. These tokens have become incredibly popular over the last few years, with the value of one Bitcoin fluctuating between several thousands of dollars.

Here are some of the main reasons behind cryptocurrency's recent popularity:

Blockchain's security makes theft much harder since each cryptocurrency has its own irrefutable identifiable number that is attached to one owner.
Crypto reduces the need for individualized currencies and central banks. With blockchain, crypto can be sent to anywhere and anyone in the world without the need for currency exchanging or without interference from central banks.
Cryptocurrencies can make some people rich. Speculators have been driving up the price of crypto, especially Bitcoin, helping some early adopters to become billionaires. Whether this is actually a positive has yet to be seen, as some retractors believe that speculators do not have the long-term benefits of crypto in mind.
More and more large corporations came around to the idea of a blockchain-based digital currency for payments. In February 2021, Tesla announced that it would invest $1.5 billion into Bitcoin and accept it as payment for their cars.
Of course, there are many legitimate arguments against blockchain-based digital currencies. First, crypto isn't a very regulated market. Many governments were quick to jump into crypto, but few have a staunch set of codified laws regarding it. Additionally, crypto is incredibly volatile due to speculators. Lack of stability has caused some people to get very rich, while a majority have still lost thousands of dollars.

Whether or not digital currencies are the future remains to be seen. For now, it seems as if blockchain's meteoric rise is more starting to take root in reality than pure hype. Though it's still making headway in this entirely-new, highly-exploratory field, blockchain is also showing promise beyond Bitcoin.
