Bitcoin callback in 2018
In the early morning of January 2, Beijing time, foreign media reported that at the beginning of the new year, the life of bitcoin has been difficult
this is the first time since 2015 that the cryptocurrency has opened a new year in the form of a sharp fall, further aggravating its decline since it hit a record high of $19511 on December 18
The surging trend of 
has given birth to a variety of other cryptocurrencies, and also made bitcoin enter the wall street in the form of futures contracts. On December 18, the Chicago Mercantile Exchange launched for the first time a derivatives agreement that some traders thought would encourage short positions, and bitcoin peaked a few hours later
virtual is always virtual
By midday, bitcoin had fallen to around $10700. Bitcoin's previous attempt to break through $12000 failed, and yesterday's downward trend continues to this day. As a result, the cryptocurrency market fell, with 90 of the top 100 currencies falling
in the past 24 hours, according to the okex platform, the net outflow amount of bitcoin reached 638 million yuan, and according to the currency security data, the net outflow amount of bitcoin reached 152 million yuan. Although the capital outflow in the past 24 hours is relatively large, it has decreased compared with yesterday's capital outflow, and bitcoin has hit the bottom of US $10600 for many times in the past 24 hours. However, in terms of trading volume, there is strong support in this position. After that, we still need to observe the withdrawal of funds, so as to confirm whether the market goes up or continues to fall below the down. In fact, the so-called "bear market" in the currency circle is more popular than the "three o'clock community" before. In my opinion, I basically dare to assert that there are makers in the currency circle who have successfully harvested a batch of "leeks" by using some financial means or big men. This view may sound like "conspiracy theory" to many people, But I have to admit that speculators are everywhere in the coin circle. Zhu Xiaohu's warning that "I hope you don't stay in history because you reap leeks to earn money with blood" also has a certain basis in my opinion
the craziest time was in December 2017, when bitcoin reached more than 100000 yuan. Before that, people who invested in bitcoin could make a fortune overnight. At the end of 2017, the price dropped to below 40000 yuan, and there was also a correction in 2018
there are two ways to invest in bitcoin
one is to buy bitcoin directly and wait for it to rise, that is, simply buy it low and sell it high. Judging from the historical data and the popularity of blockchain, there is still a lot of room for bitcoin to rise, but the cost of this investment method is relatively low, and the price of bitcoin fluctuates too much, so although the income of buying bitcoin directly is high, But the risk is also great
the other is to "dig" bitcoin with professional equipment. The total amount of bitcoin is 21 million. mining is the only way to get bitcoin, that is, through a professional computer, which is called mining machine in the instry, to get bitcoin through a lot of calculation, and then sell bitcoin to get income. At present, the price of a mining machine is about 10000, Another problem is the cost of electricity. This kind of equipment consumes a lot of power and needs 24-hour uninterrupted operation, so after a long time, the electricity cost is not a small cost
at present, there are many people engaged in mining, mostly in the form of mines, finding cheap electricity for centralized mining to rece costs
every day will generate income, the highest is more than 200. In addition, the fluctuation of the currency price has little impact on the mining, because the bitcoin can be sold at any price. Even if the price of the coin is low, it can be sold after the price rises. Therefore, the investment income is relatively stable, the risk is relatively low, and the current machine price is also low, There is no threshold for investment, so it is a good opportunity for investment
According to the current market, mining income is not high, and even some retail investors have caused losses, but it is difficult to lose money in large-scale professional mines. Mining requires the cost of machinery and equipment and the cost of electricity price. With the decline of bitcoin market, the cost of machinery has been reced again and again, and the electricity price in large mines is also extremely low. Therefore, the income of mining in large mines will be higher than the cost for a long time in the future, and the income will be higher after the price of bitcoin risescompared with self built mines, it has certain advantages to invest in mining machinery trusteeship business. Firstly, the time cost is saved to a certain extent, and the mining business can be started immediately. Secondly, unnecessary expenses, such as labor cost, are saved. Since the custody business concentrates the mining machines of multiple investors in one mine, the labor cost is shared by all investors. Finally, there are cheaper electricity prices. The ultimate goal of hosting enterprises to carry out mining machinery hosting business is to make profits. If they can not get lower than the normal electricity price on the market, it is difficult for hosting enterprises to make profits. Of course, the electricity price given to investors will also be lower than the normal electricity price on the market. Another important advantage is that some trusteeship enterprises are able to cash the virtual currency g up by investors' mining machines directly, which also relieves some investors from the worry that they can't cash the virtual currency
is mining profitable or not? There are several factors affecting the mining income: first, the currency price. The higher the currency price, the more profitable the mining. The second is the difficulty. The slower the difficulty rises, the more profitable the mining will be. The lower the cost, the more profitable the mining. Of course, the cost here refers to the purchasing cost and operating cost of computing power, including labor, network, construction, electricity and so on. The lower the cost, the better. Mining needs to deal with the risk of currency price plummeting, mining difficulty soaring, and mining costs rising. At present, the risk of mining currency speculation is much smaller
now the currency price continues to fall. Some people say that it's better to buy money directly than to buy a miner. In fact, it's not the case. Buying money must bear the risk of currency price falling, and the risk and income coexist, while buying a miner is to "protect the income from drought and flood" and keep the value of money rising; In the absence of rich market experience, the decision to buy money is only the choice of speculators
as long as the government fails to suppress policies, bitcoin will not become a bubble. According to the coin.love trading platform, the price was less than 50000 yuan. I remember that at the end of June, the price was around 42000 yuan, and it rose by 8000 yuan in less than two months. It is said that the rarity is the most expensive. At present, BTC has become the mainstream currency of digital assets
if the figure below is accurate, the price of bitcoin will rise to US $91000 by 2020
I have three bitcoins. Anyway, save them first, and they won't come out in the short term
