1. Bitpay, the largest and oldest
bitcoin payment website, has a daily bitcoin transaction volume of US $1 million and supports more than 44000 businesses.
2. Theoretically, arbitrage is possible. The difficulty is that your withdrawal (bitcoin or cash) in the exchange does not arrive at the account in real time. In the process of waiting for the account to arrive (more than 10 minutes), the market prices on both sides may reverse.
3. There must be radiation from virtual currency mining, including mobile phones and computers, not to mention mining
Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network
it can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network
this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin
however, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks
after the last bitcoin issue, mining is still necessary
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of display card, which consumes a lot of power
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency
At present, there are more than 100 kinds of
digital currency in the world
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly
nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization, which has very high mining efficiency
resources: Network - bitcoin mining machine
4. Well, it depends on the model. In fact, it has nothing to do with the graphics card and the brand. But the
computing power is stable. It's better to choose the brand machine. After all, the connection of the machine is better than that of the general assembly machine
5. Abstract: a person named Satoshi Nakamoto posted a post on the P2P foundation website, saying that he has developed an open-source P2P (peer-to-peer) e-cash system called bitcoin, which is completely decentralized. There is no central server or trustee, and everything is based on participants. Bitcoin Bitcoin is a kind of virtual currency in the form of P2P. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. Bitcoin is a kind of network virtual currency, similar to Tencent's q-coin. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million. Another point is that you can use computers to make bitcoin. Bitcoin is an electronic currency proced by open source P2P software. Bitcoin has also been paraphrased as "bitgold". The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Now bitcoin is also used to refer to bitcoin's open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution, but uses a distributed database throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin. Feature bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computer in the form of computer file (wallet) or in a third-party hosting service. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address. The distributed characteristics of P2P and the design of no central management mechanism ensure that no organization can manipulate the value of bitcoin or create inflation.
