at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability
Cryptocurrency is not a tangible currency that can be carried with you, but a digital asset that can be exchanged“ The "encryption" part comes from using encryption technology for security and authentication ring a transaction
when using cryptocurrency for exchange instead of legal tender, crypto owners do not have to rely on banks to facilitate transactions, and can successfully avoid the costs of using financial institutions
generally, cryptocurrency transactions are processed and completed through the blockchain network. The blockchain is designed to be decentralized, so each computer connected to the network must successfully confirm the transaction before it can process it. Ideally, this would create a more secure transaction for all involved. It can also cause you to wait for a while; One of the big complaints about bitcoin is how long it takes to complete the transaction
domestic cryptocurrencies include bitcoin, Ethernet, Leyte and e-dinarcoin
extended data:
bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. It is a P2P form of digital currency. Bitcoin is generated through a large number of calculations according to specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulation
ether coin: ether coin (a digital token of Ethereum, regarded as "bitcoin version 2.0"), can be bought and sold on the trading platform
lightcoin: lightcoin is a kind of network currency based on "point-to-point" technology, which can help users pay to anyone in the world immediately. At present, it is the second virtual currency after bitcoin's global circulation market value

moreover, the TDP of the former is much higher than that of the latter, which shows that Intel has left a huge space for overclocking of i7-6700k
therefore, after overclocking the i7-6700k, the i7-6700 will naturally be pressed by force. There is no doubt about this
it should be said that Intel has made the non frequency locking K version more conscientious this time
however, when it is usually used, such a big gap is not felt
if i7-6700k is not overclocking, it is similar to 6700
after overclocking, there is an experience improvement in large software.
10 is made up of 1 ten and 0 one
The answer process is as follows:(1) from the right end, the first digit is "indivial", the second digit is "ten", the third digit is "hundred", the fourth digit is "thousand", the fifth digit is "ten thousand", and so on. The number in ten represents several tens, and the number in one represents several ones
(2) 10 is a two digit number, including two digits, ten digits and one digit. 1 occupies ten digits, which means 1 10, 0 occupies one digit, which means 0 one
extended data:
the characteristic of decimal counting method is "full 10 into one". That is to say, every 10 units constitute a higher unit adjacent to it. That is to say, 10 ones are called "ten", 10 tens are called "hundred", 10 hundred are called "thousand", 10 thousand are called "ten thousand"
for the same number, because it is in different digits, it represents different values. For example, among the three numbers of 6789, 9768 and 6987, the "9" of 6789 in the indivial position means that there are nine ones, the "9" of 9768 in the thousand position means that there are nine thousands, and the "9" of 6987 in the hundred position means that there are nine hundreds
digit refers to the number of digits in a natural number. A number represented by a non-zero number is called a single digit. For example, 2, 4, 6 and 8 are all single digits. The number represented by two numbers (ten digits are not zero) is called two digits. 10, 24, 19, 89 and 92 are all two digits
