Cryptocurrencies: what they are and how digital money works
A cryptocurrency is a digital currency designed to function as a medium of exchange. It uses cryptography to secure and verify transactions and control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are met. There are thousands of cryptocurrencies, the most popular is Bitcoin, but here we will tell you about what cryptocurrencies are in general and how they work. Read on to learn more about the digital money of the future and how to understand how it works so that you can use them in a better way and learn to invest in cryptocurrencies wisely.
There were many attempts to create a digital currency during the tech boom of the 90s, with systems like Flooz, Beenz, and DigiCash all emerging on the market but ultimately failing. Among the reasons for their failures were fraud, financial problems and even friction between company employees and their bosses.
These systems were based on trust in intermediaries, which meant that there were companies behind them that verified and facilitated transactions. Due to the failures of these companies, creating a digital cash system was long considered a lost cause.
Then, in early 2009, an anonymous programmer or group of programmers under the alias “Satoshi Nakamoto” introduced Bitcoin, which was described as a ‘peer-to-peer electronic cash system. . It was a completely decentralized system. That is, it did not have servers involved or central control authority.
One of the biggest problems any payment network had to solve was “double spending,” a fraudulent technique in which the same amount was spent twice. The traditional solution was to go to a trusted intermediary, a central server, who kept balances and transactions. However, this method always gave a single authority all control of your funds and personal data.
Now, in a decentralized network like Bitcoin, each participant does this work through a blockchain system, a public ledger of all transactions that occur within the network, available to everyone. Therefore, everyone on the network can view the balance of each account.
Each transaction is a file consisting of the public keys of the sender and recipient (wallet addresses) and the number of coins transferred. The transaction must also be signed by the sender with his private key and is finally transmitted to the network once it is confirmed by its users dedicated to this task, called “miners.” Within a cryptocurrency network, only miners can confirm transactions by solving a crypto puzzle. They take transactions, mark them as legitimate, and spread them over the network. Then each node on the network adds it to its database. Once the transaction is confirmed, it becomes irrefutable and irreversible, and a miner receives a financial reward: an amount of BTC.
In essence, any cryptocurrency network relies on the absolute consensus of all participants to give legitimacy to balances and transactions. If the nodes on the network don’t agree on a single balance, the system will break down. However, there are many preconfigured and programmed rules on the network that prevents this from happening.
Cryptocurrencies are so named because the consensus maintenance process is secured with a crypto source.
What can you do with cryptocurrencies?
Cryptocurrencies can be used to pay for even a college degree.
In the past, trying to find a merchant that accepted cryptocurrencies was extremely difficult, if not impossible. Today the situation is completely different. There are currently many merchants that accept Bitcoin as a form of payment. These sellers range from online retailers like Overstock and Newegg to small local shops, bars, and restaurants. Bitcoins can be used to pay for hotels, flights, jewelry, apps, computer parts, and even a college degree.
Other digital currencies like Litecoin, Ripple, Ethereum, etc., are not as widely accepted yet. However, things have changed: r Apple has authorized at least 10 different cryptocurrencies as a viable form of payment in its App Store.
Users of cryptocurrencies other than Bitcoin can always exchange their coins for BTC. There are also gift card or gift card sales websites such as Gift Off, which accepts around 20 different cryptocurrencies. . Through gift cards, you can buy anything with a cryptocurrency. What to know about cryptocurrencies
Cryptocurrency, also called virtual currency or cryptocurrency, is digital money. That means there are no physical coins or bills – almost everything is online. You can transfer a cryptocurrency to someone on the internet without an intermediary, such as a bank almost easy. The best-known cryptocurrencies are Bitcoin and Ether, but new crypto-currencies continue to be created.
People could use cryptocurrencies to make quick payments and avoid transaction fees. Some people might acquire cryptocurrency as an investment, hoping that it will increase in value. Cryptocurrencies can be purchased with a credit card or, in some cases, through a process called “mining.” Cryptocurrencies are stored in a wallet or digital wallet, either online, on your computer or another physical medium.
Before buying a cryptocurrency, you must know that it does not have the same protections as when using US dollars. You also need to know that scammers ask people to pay you with a cryptocurrency because they know that those payments are usually irreversible.

Cryptocurrencies versus US dollars
Cryptocurrencies are digital is not the only important difference between cryptocurrencies and traditional currencies like US dollars.
A government does not back cryptocurrencies.
The government does not insure cryptocurrencies like bank deposits in the US. That means that cryptocurrencies stored online do not have the same protections as money deposited in a bank account. Store a crypto-currency in a wallet or digital purse provided by a company, and the company ceases operations or suffers a cyber attack. The government may not be able to act and help you recover the money as it could with the money. that is kept in banks or credit unions.
The value of a crypto-currency is constantly changing.
The value of a cryptocurrency can change every hour. An investment that today may be worth thousands of dollars tomorrow could be worth only hundreds of dollars. If the value goes down, there is no guarantee that it will go up again.
