1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
today's digital currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.
at the same time, in grayscale, in addition to GBTC, there are some other procts that can be traded. The price of these cryptocurrencies, such as Ethereum, lightcoin, bitcoin cash and so on, has become a large scale
what is the value of GBTC? How to interpret its meaning
stock market and currency market are two different markets. Although they are related before, they are not exactly the same. In the past, it was not feasible to invest in the digital currency of blockchain in the traditional stock market. But now there is a new way, the gray bitcoin trust (GBTC), which enables us to participate in the trading of bitcoin in the stock market. The principle is that the gray bitcoin trust (GBTC) holds a large amount of bitcoin. The value of GBTC is close to the value of bitcoin and will change with the price of bitcoin
at present, gray bitcoin trust has 6.5 billion US dollars of bitcoin, and it is a private investment. Gray bitcoin trust is a company in the United States. At present, it is the largest buyer in the world. It was launched in 2013, and it has been seven years since, The development speed is very fast.
detailed explanation of the operation mode of gray bitcoin trust (GBTC):
when an investor values GBTC and wants to buy a large amount of it, he can grab the investment fund of the foundation. The fund of the foundation can be used by investors to buy a large amount of bitcoin. After the gray bitcoin trust (GBTC) is listed on the stock exchange, Any investor who opens an account in the stock market can trade GBTC on the stock exchange. It should be noted that the price of GBTC fluctuates with BTC. The price of GBTC is close to BTC, but it is not entirely BTC. The subtle influence between the two systems determines this characteristic. At present, the price of GBTC is higher than that of BTC, and there is a certain premium. For early investors, the premium means profit, but for current investors, the premium increases the risk of current investment
why don't we buy bitcoin directly, but buy gray bitcoin trust (GBTC)
1, do not consider the security issues such as bitcoin storage
2, do not consider the legitimacy of large-scale holding, have tax incentives
3, bitcoin can not directly trade with traditional stocks, but GBTC can
