取引は簿記上，仕訳を経て勘定口座 (簿記計算の単位) に記録されるが，元帳はこの勘定口座を全部集成したもので，本来の簿記計算に直接関係のない仕訳帳や日記帳などに対応する会計帳簿の中心的存在である。元帳には企業のすべての財産，資本の増減が勘定科目に分解されて日々記入されるので，元帳を見れば企業の財産の状態，営業成績を概観することができ，また決算日など特定時点で締切れば貸借対照表や損益計算書などの財務諸表の作成が可能である。したがって元帳は簿記計算のうえで仕訳帳による原始記録から決算財務諸表という企業活動の結論を導き出すための不可欠のものといえる。しかし経営規模の拡大や取引の増大に伴う会計処理業務の複雑化から，会計帳簿の分化，再編が必要とされてきたため，元帳も個々の勘定口座に内訳を設けた多桁式のものや，本社関係の総勘定元帳と工場関係の工場元帳に分離されるなど次第に変化してきている。
In the case of Bitcoin, miners run computer programs to verify the data that creates a complete transaction history of all Bitcoin. A technology known as the blockchain, which is used to create irreversible and traceable transactions, makes the process of verification possible. Once a miner has verified the data (which comes in a block, hence, blockchain), they are rewarded with some amount of digital currency, the same currency for which they were verifying the transaction history. So mining Bitcoin, for example, would earn you Bitcoin.
Bitcoin is the world’s first virtual digital currency underpinned by a completely decentralized blockchain technology also known as the Distributed Ledger Technology (DLT). Bitcoin was first created in 2009 by an anonymous identity of Satoshi Nakamoto. Bitcoin allows for peer-to-peer transactions and is completely free of any third-party involvement like financial institutions or central banks. The Bitcoin’s blockchain network maintains a history of all the transactions made and facilitates instant funds transfer with minimal transaction fees required to cover the cost of network operation. The total supply of Bitcoin is fixed at 21 million coins and its smallest fractional unit is called as Satoshi. Each Satoshi is a hundred millionth of a Bitcoin which means 100,000,000 Santoshi = 1 BTC. Bitcoins are generated by a process known as ‘mining’ which involves solving of complex mathematical algorithms. The miners involved in the mining process look after the Bitcoin network security and validate each transactions taking place on the network. Bitcoin can be exchanged with other digital currencies or fiat currencies. Bitcoin is used as a means of payment by over 100,000 vendors and merchants.
Hey to all. Since around 2 months, I am with 99bitcoins reading and getting info and I am very happy here, thanks for a good site. For my bad luck I did not check here for a review of coinbase, I would have save a lot of worthless time. To tell the truth, I hope there is a internet god out there and shut them down. I did not know about their support in US, but as I read the first reviews here, it seems they make themselves a pretty bad place there too. I am located in the D.R.,… Read more »

Bitcoin (BTC) is the world’s first decentralized digital currency and payment system and is by far the most known and valuable cryptocurrency. It was created in 2009 by an anonymous person or group called Satoshi Nakamoto. Bitcoin enables transactions to be sent peer-to-peer without passing through a central authority. The transactions are recorded on a decentralized public ledger called the blockchain and each payment acquires a small transaction fee to cover the cost of the network. The total supply of Bitcoin is 21 million and it’s smallest unit of bitcoin is called a Satoshi, it’s a hundred millionth of a bitcoin – 0.00000001 BTC. The creation of Bitcoin’s is happening through mining. Miners have the task to validate transactions and keep the network secure. Their efforts are rewarded by new minted Bitcoins and transactions fees. Bitcoin can be exchanged for fiat or other cryptocurrencies, products and services. Over 100,000 merchants and vendors accepts bitcoin as a payment.
If you have the required hardware, you can mine bitcoin even if you are not a miner. There are different ways one can mine bitcoin such as cloud mining, mining pool, etc. For cloud mining, all you need to do is to connect to the datacenter and start mining. The good thing about this is that you can mine from anywhere and you don’t need a physical hardware to mine.
The other 2% of customer funds, held online, are covered in the event of a breach of Coinbase's online storage. Also, Coinbase holds all customer fiat currency in custodial bank accounts, on behalf of customers. So, if you have fiat currency in Coinbase, in a USD wallet, it is covered by FDIC insurance up to $250,000 (just like a "regular" bank). This protects customer assets (so long as they have been converted to fiat currency) even in the event of Coinbase becoming insolvent.
Despite the intricate technology associated with and necessary for cryptocurrency investing, speculation and possession, Coinbase has created an apparatus that makes this process remarkably easy and familiar, almost like buying and selling stocks. This screenshot from the Coinbase site shows real-time cryptocurrency prices and doesn't look too different from your ordinary online stock tracker.
On May 7, 2019, Binance revealed that it had been the victim of a “large scale security breach” in which hackers had stolen 7,000 Bitcoin worth around U.S.$40 million at the time. Binance CEO Changpeng Zhao said the hackers “used a variety of techniques, including phishing, viruses and other attacks” and structured their transaction “in a way that passed our existing security checks.” Binance halted further withdrawals and deposits but allowed trading to continue. The site pledged to reimburse customers through its secure asset fund.
Coinbase was founded in June 2012 by Brian Armstrong and Fred Ehrsam. Blockchain.info co-founder Ben Reeves was part of the original founding team but later parted ways with Armstrong due to a difference in how the Coinbase wallet should operate. The remaining founding team enrolled in the Summer 2012 Y Combinator startup incubator program. In October 2012, the company launched the services to buy and sell bitcoin through bank transfers. In May 2013, the company received a US$5 million Series A investment led by Fred Wilson from the venture capital firm Union Square Ventures. In December 2013, the company received a US$25 million investment, from the venture capital firms Andreessen Horowitz, Union Square Ventures (USV), and Ribbit Capital.
