Digital currency is paid once every four days
first line: mining, mining machine, mine (ore pool)
all three are related to mining, but they are also different
Mining: we don't discuss the technical details here. From the perspective of profit, mining has the lowest threshold. Even if we need professional mining machinery now, we can still buy a mining machine to make money. If we become bigger, we can open a mine. Without talking about the risk, mining is the simplest way to make money. The investment cost is low, the rate of return is high, and the time cost is high
mining machinery: the business of manufacturing mining machinery is very hot, and there is a high threshold, so it is difficult for non professionals to become manufacturers. Ant mining machine in the bull market does not worry about selling. Especially after 1994, as far as I know, foreign domestic ore feeders were towed away by trucks. However, the threshold of manufacturers is already very high, and it is difficult for ordinary people to get in touch with them, so there are two dealers. Mining business contact is not much, the second-hand market seems to be very chaotic
mines (ore pools) of course, mines and ore pools are inseparable. Why? The mine pool exists in order to avoid the risk of the mine. The mine pool will pay the cost of the miners according to the time according to the calculation force. Of course, it also needs to draw a percentage, and the miners will be able to keep their income from drought and flood. But the only thing to do is to bring people to the mine. Offline mines are also managed by their own machines, and can also be managed by others. There is a certain threshold, risk and income coexist
second line: information platform, exchange, wallet, currency speculation
consulting platform: something that must exist in the Internet era, providing information and consulting aggregation. The first thing new people come into contact with is information media. In the 17 years since the outbreak of digital currency, bitcoin's Internet search index has exploded. Many people want to know about digital currency, so such an information platform is sure to survive. Drainage, content, value realization and value extension are generally the ways of making profits
exchange: the best understanding is that all flows and proction currencies are for trading. Only when a transaction has a price can it be valued. Many problems will also be found in the transaction, such as the famous "bitcoin expansion". Only by finding and solving problems can the instry develop better. We all know the mode of making money in the exchange. It's the makers who make money. It's just like casinos and securities dealers. They lose more money and earn less, but the exchange is stable. In addition to the handling charges, it seems that the money charge is also a profit model. The threshold of the exchange is also high. In addition to trading risk and platform risk, it pays more attention to policy dynamics. Big exchanges now have "currency exchange", "fire currency" and so on
wallets: both hot and cold wallets are procts, and coin circles are just needed for this kind of procts. Online wallet is generally free, and then through other ways to make money, such as usually do exchanges, or there are investment activities
currency speculation: simple speculation, uncontrollable risk, too many factors affecting the price. We can envy the good luck of others, but we should not hope that we have such good luck. Therefore, there are generally three modes of currency speculation, which can be more "smart" to avoid risks: 1. Fixed investment 2. Quantitative trading 3. Arbitrage: spot move brick, futures arbitrage. Now, it seems that there is a fourth kind of profit margin in the OTC channel.
on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.
About your question, my first feeling is:
-
personally, I don't think you have a good understanding of the concept of digital currency (of course, it is very likely that I don't understand your Zheng Sisi very well, sorry). I suggest you go to the Internet search to find out the explanation of digital currency, bitcoin and other networks
-
digital currency mainly represents or narrowly refers to bitcoin, which is the world's first kind of money or wealth truly owned by a private person. This can be explained by referring to the Internet. Since it is a wealth or currency completely owned by a private person, it means that no one can freeze it or confiscate it, So there is no charge at all
-
as long as bitcoin is stored in a wallet that completely controls its private key, such as the offline paper wallet created by bitcoin offline (specific web search: Secure offline paper wallet of bitcoin), such as the paper wallet, which has never been in touch with the Internet, as long as you don't say it yourself, you will never know it again, This is the best explanation for full ownership. In that case, who will charge
-
in conclusion, if I understand your question, holding a completely private digital currency will not generate charges< br />
In a sense, it can really be compared with gold. But bitcoin is a deflationary currency, which makes it somewhat similar to gold. The new gold g every year in the world is far behind the expansion of economic scale, let alone the circulation of legal currency. Therefore, the continuous appreciation of gold can also be seen as the continuous depreciation of legal currency relative to gold
however, in the recent global economic turmoil, when the stock price and oil price fell sharply, we found that the market's safe haven funds did not flow to bitcoin, the price of bitcoin fell sharply, but the price of gold was very strong
this shows that bitcoin as & lt; Digital Gold & quot; This status has not been recognized by the global mainstream. Because the price of bitcoin is the result of the game in the global market, a small number of determined users actually have no effect on the price of bitcoin. In my opinion, the mainstream market does not recognize the hedging property of bitcoin, which just shows that bitcoin has huge risks
I think the biggest risk of bitcoin in the future is not quantum computer cracking encryption algorithm, because this risk is graally accumulated, and only need to replace the existing algorithm with more advanced anti quantum encryption algorithm. This is a normal technology upgrade, and does not affect the value of bitcoin
the biggest risk of bitcoin comes from its consensus, that is, the constant total amount of 21 million is actually realized through code, and the logic of halving every four years is also realized through code. If the upper limit of 21 million is cancelled in the future, for example, it will not be halved after this halving (around April 2020), and inflation will continue at a constant rate, that is, changing a few lines of code, It's very simple
seeing this, senior people in the currency circle will certainly laugh at me for worrying about nothing, because if we break the consensus, bitcoin will no longer be bitcoin, it will be worthless
