BTC chemical reagent

1. As a virtual digital currency in the form of P2P, bitcoin is very popular in recent years, and many people will dig bitcoin. So, what's the use of bitcoin
bitcoin is generated by a large number of calculations based on a specific algorithm. Its essence is the special solution generated by a bunch of complex algorithms, and the process of digging bitcoin is to continuously seek the special solution of the equations through a huge amount of calculation. The equations are designed to have only 21 million specific solutions, so the upper limit of bitcoin is only 21 million
so if you want to dig bitcoin, you can use the computer to dig it. You can download the special bitcoin computing tool to do the operation to dig bitcoin
of course, the more professional the equipment is, the greater the probability of being able to dig. Therefore, we will carefully select the right mining machine and pool before digging bitcoin. For example, the BTC guild mine in foreign countries is very famous. As for the mining machine, it is a computer used to earn bitcoin, but the computer is equipped with professional mining chips. After all, bitcoin is a hot card. The price of a miner ranges from two or three hundred yuan to 200000 yuan.

2. Based on the concept of "decentralization", the price of bitcoin has increased millions of times in the 11 years since its birth. In October 2009, the initial price of bitcoin was about US $0.00076/coin; On December 17, 2017, bitcoin reached the highest price in history, with a single bitcoin as high as $19142
the real price start is in October 2010. Before that, you can buy 10W pieces for 1W yuan. But this is because no one bought it, resulting in extremely low prices. If someone wants to buy 10W, the price will be higher than 1W.

PS: the above information is from China international cargo network for reference. The routes listed here are only mature routes for your reference. But it is not absolute. For example, in addition to Mediterranean Shipping, the African route is not absolute, For the middle east line, like PIL, modern merchant shipping is also good. For the near ocean line, there are more choices, such as Jinjiang, Haihua, Yantai shipping, etc, There are price, shipping date, port of call, destination agent and other factors

4. I've played too. Don't play any more. It's just deceiving. When you asked for five yuan, he said that you didn't ask until level 40. When you get to level 40, it's a lie to say how many videos you need to watch.

10. San English full name: storage area network, namely storage area network. It is a kind of high-speed private subnet that connects disk array, tape and other storage devices with related servers through optical hub, optical router, optical switch and other connecting devices

San consists of three basic components: interface (such as SCSI, fibre channel, ESCON, etc.), connection device (such as switching device, gateway, router, hub, etc.) and communication control protocol (such as IP and SCSI, etc.). These three components, together with additional storage devices and independent San servers, constitute a SAN system. San provides a dedicated, high reliability storage network based on optical channel. San allows them to increase their storage capacity independently, and also simplifies the management and centralized control (especially when all storage devices are clustered together). Moreover, the optical fiber interface provides a connection length of 10 km, This makes the physically separated long-distance storage easier.

San (storage area network) has the following advantages:

1. It can realize data sharing of mass storage devices
2. It can realize high-speed interconnection between high-speed computers and high-speed storage devices
3. It can realize flexible storage device configuration requirements
4. It can realize fast data backup
5. It improves the scalability of data Reliability and security

combined with the characteristics of San technology and its successful application in many instries, it is suitable to adopt SAN Technology in the enterprise environment with the following business data characteristics

1. Enterprises with high requirements for data security
typical instries: telecommunications, finance and securities
typical business: billing
