Bitcoin mining tools source code
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, mining is still necessary.
at present, bitcoin mining needs professional mining machines. Now bitcoin mining is a very professional thing. Retail mining has been graally eliminated, and bitcoin mining is graally mastered by several major mining machine manufacturers and owners
as long as the digital currency allows mining, it is OK to mine anywhere. As long as the network can be connected, mining generally uses ordinary computer or graphics card or professional ASIC mining machine
some digital currencies do not need to be mined, but are pre mined in advance, such as Ruitai, but Ruitai is a kind of asset mortgage certificate. Of course, most of the others need to be obtained through mining, such as Wright coin and thousand gold card mining.
on the evening of May 12, many domestic colleges and universities reported that their computers were attacked by viruses and their documents were encrypted. The desktop of the computer under attack will show that a certain amount of bitcoin will be paid to unlock
according to their monitoring, at present, in addition to the ecation network and campus network of some domestic colleges and universities, enterprises have been infected with viruses, and some civil facilities such as the computer system of gas stations have also been attacked by viruses. Although experts say it can't be cracked at present, e to the wide spread of the virus, experts from all over the world are actively cracking the virus and believe that there will be progress soon
fortunately, it is such a leaky system that it will probably never grow to a point where it will have adverse effects or impacts on the world economy
however, I feel it necessary to point out the problem
bitcoin is more like a data transmission system than a cash trading system. Well, the problem is that it doesn't make a deal by offering a digital cash deal in dollars, but by importing a whole new currency. So here we will ask, is this really desirable
one of the fatal problems: the distribution of initial wealth
when the Federal Reserve prints money, it will not issue millions of dollars of checks randomly to thousands of Americans. The work it does is: 1. Buy some other assets (usually US Treasury bonds) in the free market to inject more cash into the system than before; Or, 2. Lend money to the bank, the bank lends money to others, and finally spends the money
the important thing is that these people don't get money for free. They either sell their assets for cash, or borrow money to spend it and eventually pay it back (also paying interest)
the bitcoin system does not have a central bank to issue currency. It has an "algorithm" that allows bitcoin to be "mined" through a rather puzzling mechanism. Basically, it's randomly assigned to people who are early in the tasting season. It's a very good system for early entrants (free money!). It's a ridiculous system for real money, not to mention the obvious lack of expansibility (what happens if everyone mines all day long?) In order to solve this problem, the supply of bitcoin is algorithmically limited, which once again brings benefits to early entrants, but this leads to the second problem:
the second fatal problem: endogenous deflation
economics course time! Deflation results from the appreciation of currency relative to other commodities (such as the decrease of commodity prices). More directly, deflation occurs when people expect the currency to appreciate relative to other commodities, and the price trend continues to decline
question: if money is expected to appreciate, why do you spend it? Answer: Generally speaking, you don't spend money
the supply of bitcoin is set to slow down at a known rate. It eventually reached about 21 million. As shown in the picture
we can see the rate - well, I agree that if it is foreseeable inflation, it may not be desirable from an economic point of view, but it is reasonable. However, if it is to slow down the issuance, if you design a currency to subvert the world order, what you would like to see is this graph:
then what if there is at least a constant growth rate? You may be willing to do that, because that's the only way to adapt to more people using it
but bitcoin is not designed to be a practical currency, it is designed to make early entrants rich. Once again, it's a hoax
for a quick thinking experiment, we assume that more people use bitcoin compared with the growth of demand for bitcoin. In this way, we can expect the dollar price of bitcoin to rise rapidly. Now suppose I have a bitcoin, I also have a dollar bill, I am willing to buy a bottle of Pepsi Cola, which payment method will I use? Obviously, the devalued dollar should be spent more than the rapidly appreciating bitcoin
in the best case, the limitation of bitcoin supply will cause severe deflation, squeeze most of the business activities of bitcoin pricing, and connive at speculation in the trading market. If you are not willing to use it and others are not willing to use it, the so-called benefits of transparency and low transaction costs will not bring you any benefits< The third fatal problem is the lack of convertibility. People have a misunderstanding about the so-called intrinsic value of money. In fact, there is no so-called intrinsic value of money. The nominal value of money is limited to the other money they can trade for. One dollar is equivalent to a certain amount of euro, one euro is equivalent to a certain amount of yen, and one yen is equivalent to a certain amount of dollar. One dollar can be stored in the bank, change a certificate of deposit, and then the certificate of deposit can be changed into one dollar. It can be turned into a commercial or personal check and then into cash or deposit. When you travel, it can be changed into a traveler's check in yen or euro. If you have to pay for sandwiches, the sandwich shop also charges because the money can be converted into something else. It's a wonderful circular balance.
Two way opening in futures means you can buy or sell
< H2 >futures trading can be two-way trading, futures can buy more or short. When the price rises, you can buy low and sell high; when the price falls, you can sell high and buy low. Long can make money, and short can also make money, so there is no bear market in futures. In a bear market, the stock market will be depressed, but the futures market will still be prosperous and the opportunities will remain
the day of futures settlement can be one week later, one month later, three months later, or even one year later. A contract or agreement to buy or sell futures is called a futures contract. The place where futures are traded is called the futures market. Investors can invest or speculate in futures
{rrrrrrr}
< H2 > extended information:basic system of futures
1. Position limit system
position limit system refers to the system that futures exchanges limit the number of positions held by members and customers in order to prevent manipulation of market prices and excessive concentration of futures market risks on a small number of investors. If the limit is exceeded, the exchange may close the position or increase the margin ratio
Large account reporting system means that when the speculative position of a certain type of position contract of a member or client reaches more than 80% of the position limit (including the principal) specified by the exchange, the member or client shall report its capital and position to the exchange, and the client shall report through the brokerage member
