Bitcoin growth in December 2017
bitcoin is the first and most popular decentralized cryptocurrency. At present, there are hundreds of cryptocurrencies in the world, some of which are growing geometrically. But the main focus is bitcoin. First, it's the most expensive cryptocurrency. Second, more than 100 million people around the world are bitcoin holders. In December 2017, when cryptocurrency became popular, the price of bitcoin suddenly rose to $20000. We invested a lot of money not only to buy cryptocurrency, but also to mine bitcoin and build a huge & lt; mining & quot;, With the installation of mining equipment, almost as much electricity is consumed as in small cities. Some entrepreneurs have invested hundreds of millions of dollars in mining. Mining equipment manufacturers are doing quite well. For example, bitland's special offer integrated circuit ant miner S9 miner costs $6500{ RRRRR}
of course, bitcoin and other decentralized cryptocurrencies are extremely volatile and unpredictable assets. Therefore, the investors are optimists or professional investors without roads. Due to the unstable exchange rate, bitcoin is difficult to become a means of payment and storage tool, and cryptocurrency cannot be widely circulated. If the world economy is stable, there will be investment tools with good income forecasts

watch surface scar
for local deep scratch on watch case or strap, it is necessary to polish the local part with oilstone first. This process needs to be carried out under a magnifying glass. The purpose is to grind the wristwatch scratches evenly. When the wristwatch scratches are basically ground off, select the abrasive paper with appropriate grain size and grind it along the original sanding pattern. Generally, the pattern is radial with the wristwatch dial as the center. Therefore, this is a delicate work and needs to be done a little bit, The effect of grinding will be good and realistic
the hand-held tools are also particular. It is recommended to use the hemostatic forceps on the surgical operation. Take only a small piece of sandpaper, fold it in half, and clamp it with hemostatic forceps, parallel to the original grain for sand pulling. The sapphire glass is relatively hard, so it can be ignored. However, the watch shell is made of stainless steel. When operating, it must be careful not to scratch it, and it can be covered with adhesive tape if necessary. The technical aspect is that all the sand lines must go all the way, starting from the center of the dial and radiating
if you want to remove the scratches on the case and strap of all watches, or to renovate the appearance of watches, you can refer to this method. Straight line shape of the grain is easier to do, if the grain is concentric circle, it should still use electric machinery to do
how to repair the scratch of watch case and strap with polishing process? For the case and strap with sanding and polishing process, sanding and polishing should be done first, and then polishing and polishing should be done. It just needs to cover the sanding part that has been repaired. Simply use adhesive tape, and the more formal one needs to make metal template, which is also used to cover the polishing
use sandpaper to repair the scratch on the watch case and strap.

For this bitcoin, we all have a certain influence on it< because bitcoin has a group of people investing in 2021, it is in a very good state as a whole, which makes many people feel that bitcoin is a very good choice so they will choose to dig bitcoin at this time. We can also understand the occurrence of this event, because for many young markets, they still make us feel very good when facing this kind of thing, so what I don't understand is that nearly 20% of Internet cafes in South Korea choose to mine at this time, We all understand this, because bitcoin itself belongs to virtual currency{ RRRRR}
so this tells us that many people do not keep a good attitude in the process of choosing bitcoin, which will naturally have a very bad impact on us at this time
We invested 1 yuan in that year, and now we get 10.8 million yuan! The market value of bitcoin can buy 22 Yunnan Baiyao, which has increased by more than 10 million times in ten years. After breaking through 25000 US dollars on the 26th, the transaction price of bitcoin continued to rise< as of 14:24 Beijing time on the 27th, data from coindesk showed that the price of bitcoin was $27372 each, up more than 10% in 24 hours
the key to maintaining monetary belief is scarcity. In primitive society, shells were also used as currency. This is because people find that shells also require a lot of labor time< the scarcity of shells determines the intrinsic value of these shells but if people go to the seaside and find endless shells everywhere, the shells will become worthless and people will start to use other scarce commodities as money
or another way of thinking, assuming that bitcoin is compulsorily used as a global currency (here bitcoin can be divided or not, the result is the same), then because of the limitation of bitcoin and the normality of economic growth, only long-term holding of bitcoin, bitcoin will surely be able to exchange for more physical objects or better exchange value in the future, This will lead people not to use bitcoin in normal transactions, but to collect bitcoin, and use current paper money in transactions, which will lead to bad money (paper money) expelling good money (bitcoin), which will lead to bitcoin not playing the functions of currency circulation, value scale and so on, more like a kind of speculative goods (virtual speculative goods)
bitcoin, as an earlier and most influential free electronic money model, has undeniable positive significance (but also negative significance, such as money laundering). But this kind of currency, this kind of currency model, is easy to , and the traditional current paper money can also be electronic in the transaction process, which is easier and more realistic
in fact, from my personal point of view (Economics and finance, and it), from an academic point of view, bitcoin is not perfect. A more perfect future currency should be based on freedom, centerlessness, and electronization, plus fairness. This perfect currency model is not difficult (academic model), but it will be more difficult to implement. Of course, this kind of model will never appear in China. It's not a problem of capability. It's just that in order to avoid trouble, we prefer to publish models in foreign forums
although bitcoin is very hot recently, its impact on the macro economy can be ignored.
