It was created by Satoshi Nakamoto and the first block was mined on January 3, 2009. Bitcoin transactions are recorded on a blockchain, which is a distributed ledger that can be accessed by anyone to verify transactions. Transactions are verified by miners, who are rewarded with a set amount of Bitcoin and transaction fees. The supply of Bitcoin is limited to 21 million coins and it is divisible to eight decimal places. A wallet is needed to use Bitcoin and it consists of a public key, which is used to send and receive payments, and a private key, which is used to control the wallet. Bitcoin can be used for a variety of purposes, including everyday transactions, as a store of value, or for investment.Description provided by CryptoCompare.

It is not possible to buy all cryptocurrencies with U.S. dollars. Bitcoin, Bitcoin Cash, Ethereum, Litecoin and other popular cryptocurrencies can be purchased with U.S. dollars using Coinbase. Once you have purchased Bitcoin using Coinbase, you can then transfer your Bitcoin to an exchange such as Binance to purchase other cryptocurrencies. What do investment analysts think about Bitcoin? Weiss Research, an investment research firm that rates cryptocurrencies, has given Bitcoin an overall rating of "B+", a technology and adoption rating of "A-", and a market performance rating of "D". What technology is included in Bitcoin? Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining. Processing - mining Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends. (Information provided by CryptoCompare.)
