The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
the bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Leverage is a common financial transaction system, namely margin system
Leverage trading is also called virtual trading and deposit trading. That is to say, investors use their own funds as guarantee to enlarge the financing provided by banks or brokers to carry out foreign exchange transactions, that is, to enlarge the trading funds of investors. The proportion of financing is generally decided by banks or brokers. The larger the proportion of financing is, the less capital customers need to pay
leverage trading operation process:
1. Take BTC / usdt as an example, if the platform supports up to three times leverage
when judging that the price of bitcoin will rise from 10000 usdt to 20000 usdt, if you have 10000 usdt of principal, you can borrow up to 20000 usdt from the platform. Use 30000 usdt to buy 3btc at the price of 10000 usdt and sell it at the price of 20000 usdt, with a profit of 3btc * (20000-10000) = 30000 usdt
2. Take BTC / usdt as an example, if the platform supports up to 3 times leverage
when it is judged that the price of bitcoin will drop from 20000 usdt to 10000 usdt, with a principal of 10000 usdt (0.5btc), you can borrow 1btc from the platform, sell one bitcoin at 20000 usdt, and buy it at 10000 usdt, making a profit of 10000 usdt
if you only trade with your own funds, you can only buy low and sell high, not short
3. Calculation method of leverage lending rate:
from the time of applying for leverage, the interest will be calculated as 24 hours in less than 24 hours, and the loan funds and interest will be returned when the leverage is returned
4, the risk of leverage Trading:
leverage makes use of less capital to realize the possibility of obtaining greater returns. But if the wrong direction of the transaction is judged, the loss will also be enlarged year on year. Therefore, ordinary traders try to avoid the high leverage of heavy trading, to prevent the occurrence of burst positions or even through positions
(1) reasonable use of leverage ratio and control of position (2) stop profit and loss timely and close positions spontaneously (3) margin should be added in time to ensure that the ratio of total assets to leverage is greater than 110%extended data
related functions of leverage Trading:
1. Loan account:
each loan transaction pair corresponds to a loan account. For example, ETH / BTC will correspond to an eth / BTC loan account (including two sub accounts of Eth and BTC)
users can transfer Eth and BTC monetary assets in the transaction account to eth / BTC lending account; Eth / BTC loan account can be applied for loan in two types of currency assets: Eth and BTC
2. Fund transfer:
users can't recharge to the loan account directly for the time being, so they can transfer the funds from the transaction account to the loan account by fund transfer
(1) when the user borrows, the part of the loan account with a risk rate higher than 200% can be transferred out to the transaction account
(2) when the user has no loan, all the available funds in the account can be transferred out to the transaction account
3. Apply for loan:
the user enters the loan management and selects the loan account to apply for loan assets. The amount of digital currency that the user can apply for loan depends on the account principal and platform leverage ratio. The maximum amount of loan that the user can apply for is net asset conversion (BTC) × Multiple - 1) - borrowed assets
for example, if the maximum leverage ratio of the platform is 3 times, the number of digital currencies that users can borrow is 2 times of the principal
Take a blockchain API tool that I am currently using as an example
previously, I occasionally found bctools , which can quickly and conveniently test and verify BTC and EOS blockchain API. At the same time, these API interface test network and main network can be verified on bctools ; If you are interested, you can go http://bctools.io Use it
at present, Apis on bctools seem to have the following types:
generally, the freezing of bank cards is judicial freezing, and the reasons can be roughly divided into two kinds:
1. If the cardholder violates the law and commits a crime, for example, if he is sued for compensation, he refuses to implement it
2. The cardholder has received a sum of stolen money, which is implicated and frozen
the bank itself has no power to freeze the bank card, so it is passive to implement the court or public security orders. A large number of bank cards in the exchange have been frozen, which may be e to the inflow of stolen money
if the bank card is frozen because it has received the stolen money, the amount confirmed as the stolen money in the card will be directly transferred by the court without going through the bank card itself, and the bank card can only be unfrozen after the case is closed.
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
choose your own direction
the cost of developing an interface is not so high. Except for EOS, there is not much data to be chained, which is basically completed locally. As a top blockchain technology developer in China, weisanyun is still a good technology developer.
Ponzi scheme, it is recommended to stay away from it
whether a platform is formal or not, you need to check its supervision, and confirm whether it is really under effective supervision. You can go to foreign exchange Tianyan, 110 and so on
secondly, to ensure the safety of funds, all formal platform accounts are opened with their own ID card, and the deposit is also opened through the formal official channel, which is called to the official account. If it's a private account or something, stay away. At the same time, it also depends on whether the funds of this platform are regulated. It is better to have segregated accounts.
