What is blockchain and where did the word cryptography come from?

 A phenomenon called digital currencies with the flagship of Bitcoin has been around for many years. Especially since the second half of last year, when people suffered huge losses from the country's stock market and were looking for a way to escape the inflation giant.

The cryptocurrency market has emerged with a decentralized nature and without limiting the range of fluctuations. If you want to enter this market with the vision of "going to the centenary overnight", you must first accept the fact that you will definitely not have a positive outcome and your capital will be wasted.

To enter any market, if you invest without knowledge, you have entered the gambling game; Getting rich in this market requires knowledge, motivation, perseverance and patience.

What is cryptography?

Cryptography is a term that has been used in governments since ancient Egypt to protect information security. Over time, the cryptographic process evolved along with human knowledge, until in 1992, a project called Cypherpunk was started by Eric Hughes, Tim May and John Pilmore.

"Privacy is one of the most essential and undeniable needs of a free society today. Privacy is not something one wants at all," said Cypress Punk, focusing on the decentralized cryptographic process and issuing a cryptographic statement. "Knowing the world and keeping it does not mean secrecy. Hiding something means that no one knows about it. In fact, privacy is the power of choice for individuals to present themselves to the world as they wish."

The movement was the beginning of decentralized exchanges, correspondence, and transactions, and formed the foundation of the blockchain and bitcoin world, until in 2008 an individual or group nicknamed Satoshi Nakamoto published an article announcing the production of decentralized currency. Peer-to-peer, with the ability to make transfers transparent and limited in number.

You may say to yourself, what is the advantage of this "limitedness" ?!

In fact, it is this feature that has saved bitcoins from inflation and, like other currencies, has prevented them from being printed or reproduced. The infinity of a currency means its worthlessness and the beginning of its inflation. Bitcoin is a extractable currency. That is, there are a certain number of them (21 million) that are extracted by devices called miners and are available to extractors. It is certain that this number will be completed with certain conditions and rules until about 2140 AD, after which the mined bitcoins will be in circulation.

What is a blockchain?

You must have heard the name blockchain technology; Technology that is the reason for the stability, development and security of cryptocurrencies such as Bitcoin. Blockchain allows direct and unmediated communication in any transaction.

A blockchain is a system consisting of a series of interconnected network computers, each of which acts as the receiver or sender of a transaction; Any computer or person who uses this system is called ninety.

The purpose of creating Bitcoin was to eliminate an intermediary called a bank in day-to-day financial transactions.

Conventional ways to monetize this beautiful digital world include extracting, buying and selling, investing, and producing some cryptocurrencies.

But for buying and selling and investing, how can we find a good opportunity to buy a currency code?
