Uncle talking about bitcoin

1.

Recently, logic thinking & amp; The video of APP founder Luo Zhenyu talking about his investment in bitcoin was exposed again. In the video, Luo Zhenyu said that because he believed in the trend, he bought 100 bitcoins, which are now worth 3 million

LUO Zhenyu said that the simplest way to invest is: as long as you believe in the trend, you don't care after investing. It's more important to increase your ability to earn money

Unlike all currencies,

bitcoin does not rely on a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

on December 17, 2017, bitcoin reached an all-time high of $19850

2. Bitcoin system mainly uses hash algorithm and asymmetric encryption algorithm in cryptography to ensure the security of the transaction: on the premise of the transaction information being open in the whole network, the one-way property of hash algorithm protects the privacy information of both sides of the transaction; Asymmetric encryption algorithm can ensure that your bitcoin will not be transferred to other people's pocket ring the transaction< In theory, these cryptography principles can guarantee the realization of bitcoin's basic functions as a "decentralized currency", but it has some problems:
the first problem is system security:
we say that in the world of bitcoin, all information is expressed in the form of code through hash operation
then, where there is code, there must be loopholes, which give hackers an opportunity to take advantage of
as early as 2010, shortly after the emergence of bitcoin, a hacker took advantage of the vulnerability of bitcoin's core software to create hundreds of billions of bitcoins. It's like a person mastering the banknote printing machine. It's terrible. Or, hackers directly hack into our computers and steal our private keys, which will also cause us heavy losses
the second problem is that the transaction processing speed is too slow:
in the bitcoin system, there are up to seven transactions per second, which obviously can not meet the normal transaction requirements. We need to know that Alipay, Taobao and WeChat can handle hundreds of thousands or even millions of transactions every second. A deal can only be processed in 1-2 seconds. If bitcoin is used for daily money, then we will pay 1-2 yuan to handle it successfully.
the third problem is that bitcoin mining consumes too much power: Mining requires professional mining machines, which have high computing power, but consume a huge amount of power. Moreover, according to the current market, it is difficult to recover the cost of buying a mining machine for a year. Therefore, some people doubt: what is the significance of consuming so much power to maintain a system with such slow trading speed
the fourth problem is the regulatory attitude:
at present, the attitude of various countries towards bitcoin is very polarized: the supporting countries and retail stores accept bitcoin for payment, and there are also bitcoin ATMs; Countries that don't support it will crack down on it
to sum up, if bitcoin is measured by a monetary system, it must have various shortcomings. However, we can not deny the brilliance of bitcoin: bitcoin represents not only a new set of "decentralized" currency system, but also the origin of blockchain technology and a new ideology, which has far-reaching influence
from the perspective of bitcoin's own function currency:
bitcoin is the largest digital currency so far. It is an important application in the era of blockchain 1.0 and the first application of blockchain. Under the premise of decentralization, bitcoin realizes the functions of digital currency in the stages of issuance, payment and circulation, which is a new means of payment
from the perspective of bitcoin's underlying technology, blockchain:
with the increasing attention of bitcoin, blockchain, as its underlying technology, is becoming more and more well known by the public. Blockchain has graally separated from digital currency and penetrated into many commercial fields. Different instries hope to apply bitcoin Technology to our real life, Through a variety of application scenarios, let us get a better experience
from the perspective of bitcoin ideology:
it has set off a great ideological storm. The "decentralization" and consensus mechanism of bitcoin is a new ideology in the current centralized society. Throughout history, whether the Renaissance or the enlightenment, these are all ideological changes under specific historical conditions. The popularization of these new ideas and new consciousness will take a long time to be accepted by all. In terms of the influence of bitcoin:
digital currency has been accepted and recognized by some national markets, resulting in a large number of digital currency trading platforms and the emergence of a large number of counterfeit currencies. These counterfeit currencies have further evolved into a new financing mode, writing the myth of sudden wealth, which has also led to the proliferation of cheating under the banner of digital currency, such as air currency and pyramid selling currency
in short, bitcoin has outlined a grand blueprint, that is, the currency in the future will no longer depend on the release of central banks, but on the global currency unification. However, from the current situation, the blockchain 1.0 era, represented by bitcoin, only meets the basic functions of digital currency and cannot be popularized to other instries
however, in a word, bitcoin: there are shortcomings in the United States and China, and it is hard to cover up the edge.

3. Some of the tasks in the legendary world's King City Mission are to be handed over to the mission mine. Some task mines are difficult to dig, such as 12 copper mines and 13 iron mines. These relatively difficult task mines are very valuable. The common task mines are as follows:
iron ore: 8 iron, 10 iron, 13 iron, 15 iron, more than 15 iron
copper ore: 12 copper, 15 copper, more than 15 copper
silver ore: more than 15 silver ore
blackbody:
more than 10 black iron
in addition to the task mine required by the Royal City Mission, other mines, such as gold, silver, copper and iron with purity of more than 15 plus a piece of wood, You can use it to forge your destiny. If you are lucky, you can forge your destiny at level 35, especially the soldier's. Black iron of various purity can be used to upgrade weapons, and black iron of purity more than 20 can be used to forge Dark Armor of stepping on cloud. The price of task mines varies from district to District, and the price of all kinds of task mines is also different. For example, the price of black iron above 20 is 100W in our district, and the price of black iron of 20 in our district is 1 yuan. So a lot of people can make money by mining~~~

bitcoin's biggest drop in three months: the price of bitcoin in New York market has dropped to $6840.

5. I have been trading bitcoin for many years. I have used many trading platforms. Overall, okex is better. It's the best platform I've ever used. I really highly recommend it.
