What is Crypto Currency? What are Bitcoin and Ethereum? A Beginner’s Guide

Bitcoin is the world’s most popular cryptocurrency. Created in 2009 by an individual or group using the pseudonym Satoshi Nakamoto, Bitcoin is a digital currency that operates using blockchain technology and allows for transactions to take place without the need for a central authority.

Cryptocurrency is a type of digital currency. Cryptocurrencies operate on a distributed ledger system that allows transactions to be made without relying on a central authority. This ledger system is called blockchain technology, and each transaction is encrypted and recorded on the blockchain.

Cryptocurrencies provide the opportunity to make secure and anonymous transactions. Cryptocurrencies like Bitcoin, Ethereum, Litecoin, and Ripple have become popular worldwide. Cryptocurrencies can be bought and sold like other currencies and can be used on many online platforms.

Cryptocurrencies may have more volatile values than traditional currencies. Therefore, it is important to conduct thorough research and understand the risks before investing.

What is the Bitcoin Supply?

The supply of Bitcoin is limited to 21 million Bitcoins, and approximately 18.8 million Bitcoins are currently in circulation. The supply refers to the total amount of Bitcoins that slowly come into existence through the process of Bitcoin mining, and it is designed to become increasingly difficult over time. Therefore, the supply of Bitcoin is limited, and as demand increases, its value may also increase.

What is Ethereum ?

Ethereum is an open-source blockchain platform founded by Vitalik Buterin in 2015. Unlike Bitcoin, Ethereum is designed to offer more functionality and programming features and works in conjunction with smart contract technology.

With the use of smart contracts, Ethereum enables the development of decentralized applications (dapps). These dapps can be useful for businesses, organizations, and even entire industries, utilizing programmable contracts. Ethereum is also used to develop popular cryptocurrency applications such as decentralized finance (DeFi) and unique tokens (NFTs).

Ethereum provides many benefits, including fast transaction speeds, low transaction fees, the ability to conduct transactions in a decentralized manner, and the ability to conduct more secure and transparent transactions. As a result, Ethereum has been adopted by many individuals and organizations and holds an important place in the world of cryptocurrency.


Blockchain is the fundamental technology behind Bitcoin and other cryptocurrencies. It is a decentralized digital ledger that securely and transparently records transactions. Each block in this ledger contains valid transactions and the hash value of the previous block. The blocks are linked together in a chain, making all past transactions traceable and immutable.


An altcoin is any cryptocurrency other than Bitcoin. Altcoins can use blockchain technology, which is the foundation of Bitcoin, or be based on different technology. Many altcoins have features such as faster or more secure transactions than Bitcoin. Examples of altcoins include Ethereum, Ripple, Litecoin, and Bitcoin Cash.


Mining is the process of verifying transactions on the blockchain network and earning new coins as rewards. Miners use specialized hardware to solve complex mathematical problems to add transactions to the blockchain. This process is a mechanism that ensures the security of the blockchain network and helps distribute new coins to miners.


A wallet is a software program or hardware device used to store and manage your cryptocurrency assets. Wallets store your private keys, which allow you to control your coins. Wallets can be used online or offline, and each has its unique advantages and disadvantages. For example, online wallets are more easily accessible but are more vulnerable to online security threats. On the other hand, offline wallets are more secure but require more effort to use.


Initial Coin Offering (ICO) is a method of fundraising for cryptocurrency ventures. ICOs provide funds to investors in exchange for cryptocurrency tokens or coins. ICOs are typically done when a project or idea is still in the development stage and promises potential returns to investors in the future.


Decentralized Finance (DeFi) is a new trend in the cryptocurrency world. DeFi is a decentralized financial system that replaces traditional financial tools. DeFi is a system that uses blockchain technology and smart contracts to replace banks and other intermediary institutions. DeFi applications include lending, borrowing, liquidity provision, and token exchanges.


Non-Fungible Token (NFT) is a new concept in the cryptocurrency world. NFTs are representations of unique digital assets (such as artwork, music, or videos) on the blockchain. NFTs are unique and have a specific identifier, unlike other cryptocurrencies. Therefore, NFTs are typically used for the trading of unique digital assets.


A stablecoin is a cryptocurrency that maintains a stable value, unlike other cryptocurrencies. Stablecoins are usually tied to a fiat currency (such as the US dollar or euro) and provide a stable value even in a volatile market. Stablecoins are used by investors who want to avoid the volatility risks when trading cryptocurrencies.


Consensus is a mechanism used to ensure the accuracy of transactions on the blockchain. Consensus is an agreement where all participants in the blockchain network agree to participate in transactions. Consensus ensures the security of the blockchain and prevents transaction manipulation.


A fork is a separation between two or more versions of the blockchain. Forks are typically done by a group that doesn’t accept changes or updates to the blockchain. Forks create a new version of the blockchain, which may have new rules and features.

Hash Rate

Hash Rate is a term used in mining. Hash Rate indicates how fast and efficiently a miner can add transactions to the blockchain. Hash Rate measures the processing power of mining hardware and can affect mining profitability.
