Blockchain for buying and selling US dollars
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
blockchain asset trading platform is still in its early stage. It does not mean that it ranks first now, and it will rank first in the future. Bitcoin China (BTCC), a digital currency exchange that once flourished - once accounted for 80% of domestic digital currency trading volume, failed to exit the market
according to coinsmart, there are more than 300 exchanges at present, and coin an is the top ten trading platform, but not the first
you can't help it if you have money
To tell you the truth, this question will become very big if it is unfolded. If I want to write clearly my personal feelings from the beginning to the end, it will become smelly and long. So I want to use a few simple aspects and my personal views to answer this very difficult question
let's briefly talk about what bitcoin is, because this simple problem is misunderstood by most people at present. Because it is called "bitcoin", because there is a currency, this word naturally equals to RMB, US dollar, franc and other legal compensation currencies. In fact, this is totally wrong. The definition of legal currency is "the currency given by the state in the form of law for compulsory circulation". When bitcoin appeared, it was written in the white paper that the e-cash system was completely realized through point-to-point technology, which enables online payment to be directly initiated by one party and paid to the other party without any financial institutions
so what exactly is bitcoin? To be exact, it should be regarded as a commodity rather than a currency, because you can see in the white paper that "there is no need to go through any financial institutions". When bitcoin was created by Nakamoto, it was intended to change the life of the bank which was not trusted by the people because of the economic crisis. But we say the vision is good, but the reality is cruel. Even Alipay with 1 billion users can't get rid of the bank's life, let alone a small bitcoin. p>
but you can say why bitcoin is still used by many people for trading and its price is not low, that is because its market demand is very large, resulting in its high price. What is this demand for? Let's talk about it next time. In a word, its high market demand leads to high price. What is bitcoin? I prefer to compare it to a hard currency or a very scarce commodity. Like gold. Let's take a look at an interesting figure:
to tell you the truth, the development of blockchain is very, very early now. All of a sudden, so much capital has poured in, which makes everyone crazy. When the slump comes, it's a bit at a loss. Now the price of bitcoin is more stable, which gives more time for many people who are calm down to do things
out of trust in blockchain technology, bitcoin, as the genesis currency of blockchain, will have a place in the future. Money price is not the most important thing. But make a bold guess. Bitcoin or digital virtual currency will definitely recover in early 2020 and mid-2019. The bull market will come at that time. Is it possible to go back to $2W? Maybe more. Maybe
in the future world I imagine, blockchain technology will surely create a happier and better future for mankind. And the accompanying bitcoin will certainly lead to a bull market
is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>
digital currency: to improve the convenience of currency issuance and use, for example, the central bank plans to issue its own digital currency; Cross border payment and settlement: realize point-to-point transaction and rece intermediate costs; Bill and supply chain financial business: rece human intervention, rece costs and operational risks; Securities issuance and Trading: realize quasi real-time asset transfer and accelerate the speed of transaction clearing (European crowdfunding is a typical model); Customer credit investigation and anti fraud: rece the cost of legal compliance and prevent financial crimes.
developers usually have a single real estate, that is to say, two or three real estates can be developed at the same time. That is to say, when you go to the sales office, you can only understand the situation of two or three real estates at most, and the range of options is relatively narrow
real estate agents can represent more than a dozen real estate projects at the same time, and they may have dozens or even hundreds of real estate projects in their hands. At that time, you can choose from them carefully and compare the advantages and characteristics of multiple real estate projects at the same time< In order to sell the new real estate as soon as possible, the developers, in addition to their own sales force, are bound to contact intermediary agencies of a certain scale to help them sell
if the selling price of a developer's sales office is cheaper than that of an intermediary agency, no one will buy a new house from an intermediary agency. It will be unnecessary for a developer to find an intermediary agency to help him sell, so it may be cheaper to find an intermediary agency to buy a house
to avoid the potential risk of house purchase
we all know that there must be a pre-sale or sales license for the sale of a new house, but if you go directly to the sales office to buy a house, whether the developer has obtained the certificate or not, unless they show it to you, you will not know, and the risk of house purchase will be greater
however, if the new house has been represented by an intermediary agency, it will prove that the property has complete documents and can be sold in advance or cash, because if there is a problem with the house, the intermediary agency will not act as an agent, otherwise they need to bear legal responsibility
agents can help you negotiate with developers.
if you buy real estate directly from developers without middlemen, it is very difficult to apply for a relatively large discount, and if there are intermediary agencies involved, they can play a certain lubricating role
in the whole process, the real estate agency will help you negotiate with the developer. In order to facilitate the transaction, it will try its best to apply for the largest possible discount for you.
