The calculation method of virtual currency
litecoin (LTC), released on October 7, 2011, is the most valuable counterfeit coin at present, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million
this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)
compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being
the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners
ppcoin
ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age
ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million
ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity
ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<
ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency
terracoin
terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years
however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency
namecoin
namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011
namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time
this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name.
Calculation formula: (current latest transaction price (or closing price) - opening reference price) ÷ Opening reference price × 100%
general situation: opening reference price = closing price of the previous trading day
ex dividend date: opening reference price = ex dividend reference price
< H2 > extended data
the rise and fall range is the description of the rise and fall value, expressed as%, the rise and fall range = rise and fall value / yesterday's closing * 100%. The value generated by comparing the latest transaction price (or closing price) of the current trading day with the closing price of the previous trading day. This value is generally expressed as a percentage. In China's stock market, the price limit is set, so there is a saying of "price limit"
some people want to see more regulation of bitcoin, because when the government regulates bitcoin, it will claim that bitcoin is legal or illegal. If it's legal, the laws governing bitcoin can help people measure its availability and longevity
on the other hand, some of us are afraid of government regulation, because the overall view of decentralized money is to keep it decentralized so that no one can control it. The government controls the amount of legal tender in circulation in the country. They can make more money, but they can't directly rece the amount in circulation. Wallet address storage bitcoin and wallet may be accidentally deleted, or they may be locked by forgotten password, but only 21 million bitcoin will be cast. This allows the value of bitcoin to increase over time rather than decrease
now imagine the government's announcement that they are only allowed to exploit cryptocurrency, and only their currency is legal in their country. Well, now we are in the same situation as before the invention of cryptocurrency. The government takes all the money, and they can start and stop mining at will. Maybe they'll even change the code to do more money mining when there's not enough money. The only difference is the form of the trading currency. Cryptocurrency regulation can bring a lot of terrible things, and some people are very afraid of the new rules
those who promote the regulation of bitcoin will buy more bitcoin and increase the value of bitcoin, but those who are afraid of government regulation may start panic selling when news such as nydfs bitlicense comes into play. This makes it possible for government regulation to affect the price of bitcoin. The price of bitcoin is stable. You can explain the news in two different ways
factors affecting the price of bitcoin 6: acceptance of bitcoin
no one uses bitcoin as currency, and bitcoin will not be used for any purpose as currency. When people pay with bitcoin, they are increasing their credibility and showing the world that someone wants to pay with bitcoin. Many people in companies like Dell, Newegg, and dish networks have taken the power of bitcoin to inform and allow customers to use it to buy their procts and services. Xapo offers a new credit card that allows you to use bitcoin for stores that accept regular debit cards
although shoppers have no direct impact on prices, they do help spread bitcoin around the world as a viable currency. Therefore, the impact of bitcoin shopping on bitcoin price factors has no short-term impact, but they provide a larger market
factors affecting bitcoin price 5: Mining
the more miners there are, the more secure the network will be as long as no one owns 51% or more of the network. When an entity owns at least 51% of the mining power in the network, 51% of the attacks may occur
for example, a person can buy a mansion with 10000 bitcoin. The real estate agent who sells the buyer's mansion receives the money and transfers the contract to the buyer to complete the transaction. Buyers now have luxury homes, and real estate agents get 10000 bitcoins from sales, right? Well, buyers have 51% of the bitcoin network hash rate, and they want to return their money while keeping the house. The buyer allocates the block chain before the transaction, and uses 51% network hash to compete for the official part of the fork, so that the new branch is longer than the original branch. In doing so, the entire network now treats the new branch as legal and the original branch containing 10000 BTC transactions as illegal. That means the buyer now has his 10, 00 BTC back. This is called a 51% attack
the 51% attack probability that affects the bitcoin price is the potential panic selling
e to several reasons, the impact of general mining, bitcoin price factors declined slightly. Some miners keep their bitcoin as part of their buying and holding strategies, while others cash in legal tender. Miners also have high electricity bills to run their equipment, so they often sell a large profit for legal purposes in order to pay for their electricity bills
factors affecting the price of bitcoin 4: media opinion
the media does play a role in the price of bitcoin
when most people read the news, most people will take action based on the news. For example, if the news says ghash. IO has 51% network hash value; Some people may launch DDoS attacks on ghash. Io. In front of the mountain, China's news trading is quite profitable. GOx crashes. People will sell panic crazily, so everyone who knows the latest news knows that the people's Bank of China will pitch on bitcoin, and then it will become a rumor that they will sell their collection and buy it back when the market starts to rise again
the key factor influencing the price of bitcoin in this news is the articles it provides. People will buy or sell bitcoin according to its content and send it with higher or lower value correspondingly
factors affecting the price of bitcoin 3: large enterprises mp money
bitcoin is not accepted everywhere; Not every employee wants to accept bitcoin's salary, and not every government system will accept bitcoin and other taxes. Before the world catches up, there are still things to pay in fiat money, so companies usually sell most of bitcoin to pay for their business. Just like the so-called "mping", the value of bitcoin will be in a low state. Depending on the company's sales volume and how many companies were selling bitcoin at the time, this could mimic "panic selling" and cause the price of bitcoin to collapse
the decline in the value of bitcoin is the key factor influencing the price of bitcoin for large enterprises that prefer fiat money< As you can see above, the common reason why management factors work in this way is that they buy and sell bitcoin in other currencies. When traders sell bitcoin on the exchange, the price is very low, and the price usually doesn't change, or the change is very small. If the trader is a large holder of bitcoin, that is, a person with a large number of bitcoin about 1000 + BTC, the price of bitcoin will drop significantly e to its large sales. Generally speaking, orders from large number of cash holders will not be filled with a single price, which is the reason for the price decline. Someone may buy a BTC for $600; Another may buy 20 BTC for $598; There may be more transactions of different values in the middle, and then the seller will sell 0.1 BTC to the buyer for $500. What is the new purchase price of bitcoin? Maybe 499 dollars
for all people selling bitcoin in the transaction, the price factor of bitcoin is always a decline in the value of bitcoin
factors affecting the price of bitcoin 1: trading volume and frequency of exchanges
of course, the primary factor affecting the value of bitcoin is how many people are willing to pay for bitcoin. When you place an order at the exchange to buy bitcoin, you can determine the value of bitcoin to you. The more people are willing to buy bitcoin, the greater the chance of increasing the overall value of bitcoin. The seller sells the highest bid first, so whoever is the current highest bidder is the one who decides the value of bitcoin
when someone buys bitcoin on the exchange, the factor that affects the price of bitcoin is that the value of bitcoin always rises
a formula for calculating the stock price
the rise and fall of the stock is calculated by comparing the closing price (or current price) of the trading day with the closing price of the previous trading day
calculation method of rise and fall range: the difference between the closing price (or current price) of the day minus the closing price of the previous trading day and then dividing the closing price of the previous trading day
calculation formula of rise and fall range: Rise and fall range = (current price - yesterday's closing price) / yesterday's closing price * 100% (the calculated value is positive for rise and negative for fall)
at present, the trading rules of Shanghai and Shenzhen stock markets are as follows: generally, the maximum limit of the rise and fall of each trading day is + - 10% for stocks, + - 5% for St stocks, and + - 44% for new stocks on the first day of listing, and the rise and fall of other special regulations are calculated separately
some platforms are calculated by 24 hours, some by day, and some by average price. Specific algorithm or to ask the relevant trading platform, this is no standard answer
there are risks in digital currency investment, especially since digital currency has recently entered a bear market, investment should be more cautious. It is better to invest in mainstream digital currencies such as bitcoin, bitcoin cash and wikilink, which have passed the test of the market.
