What is Cryptocurrency?

Cryptocurrency is a virtual or digital currency. It does not exist in physical form. Cryptocurrency uses cryptography which makes it nearly impossible to double-spend or counterfeit. The first cryptocurrency, Bitcoin, was made by an anonymous computer programmer or a group of computer programmers in 2009. Before Bitcoin, there was another cryptographer named David Chaum who developed an early form of cryptographic electronic money called eCash in 1990.

The key points to know about cryptocurrency is that they operate decentralized networks using blockchain technology. This technology allows them to be out of reach of agencies and governments. They are not directly controlled or monitored by governments, however some countries have specific guidelines and others are cautious about it.

Cryptocurrency uses blockchain technology which is a connected set of information blocks on an online ledger. Each block contains verified transactions which makes it difficult to forge transaction histories.

Other than that cryptocurrency has a secure method for payments and transactions. It enables secure online payments without intermediaries. It relies on encryption algorithms and cryptographic techniques to safeguard transactions. Examples of cryptocurrencies can be Bitcoin (BTC), Ethereum (ETH) and many more. Each of these currencies have their own unique features.

Lastly, we need to remember that although cryptocurrencies have many advantages like decentralization and faster and secure transactions, they have disadvantages too. For example, they can face challenges such as price volatility and energy consumption.

World GDP and the Future

Photo by David McBee Gross Domestic Product (GDP) measures the monetary value of all products and goods produced within a country’s border in a specific period of time. It calculates the total output of a nation. There are different types of GDP, such as Nominal GDP, Real GDP, and GDP per capita. Nominal GDP focuses on the raw GDP without considering the inflation, only current prices. Therefore, it may not be a hundred percent accurate and may include overstated or understated economic growth. Real GDP calculates the actual economic growth regardless of price changes. The inflation is adjusted by using constant prices from a base year. It is an effective method of learning about economic growth without the impact of price changes. GDP per capita is the GDP divided by the total population of a country. It measures the standard of living and average economic output per person in that nation. Our today’s focus is, however, not on any of the above types of GDP. Here we w...
