1. The nature of the two currencies is different: bitcoin is an encrypted digital currency, and Morgan is a typical MLM currency

(1) bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman

(2) Morgan is a kind of typical MLM currency, they often promise high income, the information of the founding operation team is not open, and they have the background of international large companies, so they put forward a set of seemingly reasonable economic theory

extension data: the harm of

network currency: the extensive application of

1 and virtual currency is also accelerating the rampant network robbers.

(1) in December 2006, the Shenzhen Public Security Bureau announced that it had cracked the country's largest theft network virtual property case, and 11 suspect was arrested. The gang used trojan virus to illegally steal virtual property such as tens of thousands of QQ numbers and QQ coins, and sold stolen goods on the network, making a profit of more than 700000 yuan

(2) in this case, the virtual currency Q was used as the standard of conviction and sentencing, and the police's arrest of illegal elements on suspicion of theft is a special case. The reason is that Tencent has filed with the Guangdong Provincial Price Bureau, and one q is equivalent to 1 yuan

(3) online currency is used more and more widely, for example, it can be used to buy anti-virus software online, vote for super girl, and some websites even use online currency to pay the moderator

2. Outside the business system, because indivial virtual currency has become the "equivalent" of RMB, or even "online RMB", which shows the role of "network hard currency", the illegal gains of illegal gambling can be cashed into RMB, which further promotes online gambling

3. As for the recording disk, Tsinghua can use it, and pioneer is the best recorder (personal opinion), but there are few good pioneer agents in China. Sony is good, read disk and burn are excellent, as long as you do not object to using Japanese goods, is a good choice, do not use MSI. Don't use Samsung. I've tried all these, garbage in garbage (personal opinion). Support the domestic procts, please use Jianxing domestic best (or personal opinion), pirates favorite, thick leather and easy to operate (unit boys say) read disk is good, burning is also good. The price is also cheap. After sales, anyway, my side is OK. If you have any problems, you can replace them. I just recommend the brand and model. You can see for yourself. It's almost the same anyway
in addition, you can go to the recording bar to have a look. It's all about how to choose and buy. You can also learn from the bad goods you buy. I went there before I bought it
the above are personal opinions, please don't scold me. Hee hee^^

4. BenQ dw1670 is good
in the first part, let's talk about the ordinary DVD drive

generally speaking, few computers do not have a CD-ROM drive. Otherwise, it will be troublesome to install the system. As for the slogan that CD ROM is enough for some Rightists, it must be comparable to frog in the well. Nowadays, in big cities, piracy is basically DVD (so is data), so it's better not to buy a CD-ROM drive

first of all, optical drives are relatively non-technical procts, and few of them are made by themselves. Large manufacturers usually hire OEM to manufacture optical drives, so you can know about their procts by looking at OEM manufacturers. Some people are unconvinced and say that Foxconn's motherboard can be compared with ASUS's motherboard. Of course, it can't. the motherboard has technology. ASUS and others design, proce their own design drawings and require their own components. The OEM is just an assembly role. Even so, the quality control requirements are very high, So I agree that OEM is naive in the motherboard instry (even if it's a domestic OEM of qixx), but for something as common as optical drive, it's not so demanding. The OEM level is very low. Generally speaking, there's little difference between OEM and panel. Therefore, it's easy for optical drive experts to guess who is OEM at a glance. Some people also asked if it would be like a liquid crystal display; OEM & quot It's more accurate to say that the manufacturer of the panel will change frequently. The CD-ROM drive doesn't have as much fluctuation as the LCD panel. Even if it's replaced, the manufacturer with a more rigorous attitude will change the model. In addition, there are rumors that the quality of different OEM brands proced by the same assembly line is different. In fact, it's sour grape psychology. The good is the brand they superstitious in, and the bad is the brand they don't believe in. At least, this kind of rookie level "knowledge" has existed since the era of CD-ROM drive. Unfortunately, there is no evidence so far, On the contrary, it is credible that the OEM quality is exactly the same, because there are countless pictures of machine dismantling on the Internet, so you can observe the details. Generally, firmware (also known as firmware) can brush each other. In addition, the official also readily admits it

there are many brands of optical drives. Take the well-known ones for example, I feel that there is little difference between them. The disk reading ability and service life are not as good as those of the previous era. However, the price is also in front of us, so I suggest that the optical drive should be slightly ignored. Taipower, Samsung, LG, BenQ, Xianfeng (note that I'm patriotic, this article is just a technical article) are not much different. Some people buy it for a month and hang it up. Some people use it for two years and don't need to care. What's more, don't be greedy for the CD-ROM. it's the best way to read the CD-ROM. it's not a big problem if you can't read a movie from a stall. The poor quality of the pirated CD itself is also the reason. But at the critical time, you can't even install the XP installation disk, which is very good. Of course, the life of the CD-ROM drive is also related to the use method and frequency, environment, hardware power supply, and whether it is fake or repaired. It's a lot of luck. By the way, since the maximum is only 16x, there is no big difference in the speed of the CD-ROM drive, and it is not likely to cause disk explosion; However, for the sake of selling points, many manufacturers urge the proction of CD-ROM "reading king", often sacrificing their life. Because the quality of CD-ROM reading is basically the same as that of optical head (generally DVD drives are Sanyo, pioneer and Philips). In order to improve the reading ability, it is necessary to dynamically increase the power of optical head, which is very bad. The optical head is fragile, so the better the reading ability is, The sooner you hang up. By the way, there is also the locking area. That's a good thing. The optical drives sold to developed countries are basically locked (rpc-ii regulations). Besides, I haven't bought any discs that need to be replaced for several years now. It doesn't matter. In short, there is little difference between optical drives. Secondly, there is no or even reaction in disk reading ability. Thirdly, it is boring to care about the lock area

now I'll talk about the most famous ordinary optical drives:
1. Pioneer, pioneer's optical drive used to be very good or even the best, such as the most famous 121sa (it has been discontinued for a long time, and now even if there is one, it is mostly repaired). I remember that when I bought it, it was more than 400, and the price was more than half of that of my peers. Sucker type is also very cute, but in addition to the very slow disk recognition and poor disk compatibility, the others are very good (pay attention to the era of 121). Later, e to the DVD price rection, profits fell sharply. So there is a big price rection of avant-garde. Unfortunately, many experts are too nostalgic and always emphasize avant-garde DVD on the configuration list. At present, pioneer's successor models, such as 122 and 123, have changed their control chips from Panasonic (mn103s71) to Ali and MTK (MediaTek's mt1355pe) in order to rece the price, and they have become short fuselage (2m buffer is very minor), which has greatly shrunk? Note that since we don't need to deal with lens technology, Sanyo, pioneer and other optical heads are almost the same (the same is true for low-end recorders). The role of the master chip is as important or even more important as the motherboard. Of course, pioneer's optical drive is of medium quality, which is not as hard as Sony's, Even though the price is too high, I think DIYer, who is used to pioneer, can give e consideration to a change of taste (people who are equipped with machines are generally used to some kind of CD-ROM drive). Now Pioneer has no advantage. In the words of a boss, plus the name of pioneer, it can also enter your vision. In addition, vanguard's 123 (black dvd-123d, off white 123A and silver 123e) has completely cooperated with ASUS, so people who know a little understand that asus's procts are completely vanguard's procts (for the complete reason, please see the recorder section), but asus's CD-ROM has multiple mute functions (in fact, vanguard's also has, but it's not vanguard's main), so it's better to buy ASUS's. Because ASUS does it all by itself. ASUS also has a mute function. The most important thing is that Asus has a good service, at least better than vanguard. Most people with backgrounds such as BenQ, LG, Samsung and ASUS have good channels and services (relatively good, at least better than Sony, vanguard and NEC)< It's not my prejudice that Sony's CD-ROM drive has a bad reputation in the mainland market. Its d162x and 163x are completely made by BTC (among the CD-ROM OEM manufacturers, there are no classic procts, the spokesperson of LJ). In addition to the good-looking appearance and the strong channel ability of the agent Qixi, the initial disk reading is very strong. Unfortunately, the typical service life is low, Recently, I also said that XD is the king of disk reading that adapts to China's national conditions. However, Sony 1615, which has been discontinued for a long time, is good. Lite on (Jianxing) is OEM. This is the quality of Sony. Of course, when we talk about Xianfeng and Sony, we don't mean that they can't make things. The main reason is that they are not satisfied with the lower absolute profit. For example, Xianfeng proces laser heads by itself, and it is a large optical drive factory (now it has been entrusted to ASUS). Moreover, its own optical heads are very good, but they often don't use their own things. Obviously, they feel that their own things are too expensive to be worth the loss, But many people don't know it's good. Instead, they can't sell it and lose the market. Price and quality are always the opposite. Especially in China with low cost and low technology, vanguard has done this several times before, and each time it won the scolding. Why 121 is so impressive today is that 120 is too LJ, In order to rece the cost alone, Taiwan's worst master chip has brought its disk reading, noise and heat to the bottom. In order to save face, it has used its third-generation laser head and Panasonic's master chip. They are both good things. They are very popular, and the profit is low. In particular, last year, the price of optical drives began to drop, so it took advantage of 121's face to give 123 to advocate short fuselage, The main control chip is cheaper than the MT before. It keeps repeating. Once it attracts you with high quality, next time it makes money with low quality, and next time. However, the worst and strangest Japanese CD-ROM driver is Sony, which invented CD-ROM and CD-ROM drive with Philips. They are very good at optical head technology alone. Just look at the high-end CD player. Unfortunately, Sony is only the most active in development. When it proced, it found a OEM (mainly collecting royalties). In order to maximize profits and rece costs, the measures taken are nothing more than sacrificing quality and seizing the market, This kind of practice is not surprising in China, the backward procts can not be sold out of the procts sold to China, the global quality control to sell to China as the worst (buy burn disc must be very understanding). Sony is even more so. It's a BTC thing to harm others, but our country's is a good thing of Jianxing OEM, XD< BenQ, in the field of Optics and magnetism in mainland China, BenQ is a heavyweight manufacturer with large output. There are so many OEM manufacturers. Is the quality of BenQ average? There are good and bad works. It's fair to buy them. At least BenQ supports domestic procts. The new 1650v series has good disk reading ability and noise control, and its service life is not bad, It's much better than before. Stupid ball (nickname) is easy to buy. What's worse is that many mentally unhealthy people in China like domestic procts to be light (that is, they look down on domestic procts, worship foreign brands, and get angry easily). I don't think it's objective. Stupid ball has only been doing storage for a few years, and has made great progress. At the beginning, his procts were really not very good, At least I've tried crocodiles and the like. I'm not satisfied with them and I dare not buy them. But recently, the proct quality is pretty good. In fact, you can see from the CD-R of stupid ball. It was not impressive before, but now it has almost unified the mid-range CD-R market. If you ask someone, almost all of them are BenQ 52X new platinum (except music discs). And it is also true that DVD drives are generally streamlined. In a word, stupid ball is OK. Its quality is at the same level as pioneer / ASUS. It's worth buying. Of course, it's not much better. Ali m5721d master chip is just of ordinary quality. The price is there. It's convenient to buy. By the way, there are three steps to attack the stupid ball CD-ROM drive (not the recorder):
1. Renhong has a lot of right and wrong. The quality of his CD-ROM drive has been analyzed before, which is just the mainstream. It has a large output and shallow initial experience, but the CD-ROM drive itself has good and bad, indivial differences are big, and it is often attacked
2. Because it's made in China (although many foreign top brands are made in China), the domestic one must be very bad, and the domestic one is not a famous brand. So once the one who bought the stupid one is broken, he will be full of grievances, yelling, eloquence, tears, and criticism. On the contrary, if even very ljsony, silent, guilty (Nissan, presumably good, I may be indivial bar)
3. Wave after wave of criticism makes novices have to buy pioneer 123, or even Sony 1632, who has a good reputation, and spend money wrongly< Li Te on Jianxing, as an optical drive manufacturer in Taiwan (note that Jianxing is not equal to Yuanxing, which has registered trademarks in mainland China), has a very good technical strength. Its popularity in professional forums is second only to that of Procter. Generally speaking, anyone who knows a little about optical drives likes Jianxing. It's cheap and the workmanship is good. Many large manufacturers have come to it for OEM, and its reputation is very good, Things are stable. Unfortunately, Jianxing's sales in mainland China have not kept up. It is not popular. Jianxing's advantages can be said that all aspects are up to the middle level. In particular, DVD formats have good support performance, good disk reading and service life. It's just that disk reading is noisy. Unfortunately, there are not many purchases in mainland China, because many tier-2 cities don't have to sell, and big cities don't have all kinds of procts. Specifically speaking, at present, there are three: gold, silver fox 167t (panel)

6. Any so-called direct selling company without direct license is not a real direct selling company, but a pyramid selling company
there is no such thing as you said among the companies that have obtained direct marketing license nationwide
in addition, as I said just now, it is unreliable for them to obtain direct marketing license directly if they publicize and associate with other licensed companies
in addition, if they publicize that they are applying for a direct marketing license, it is not credible, because it is very difficult to apply for the license. As long as they do not get the license for one day, it is illegal pyramid selling and is not protected by law.

7. Mitsubishi's is the best, TDK is also quite good, and Sony's plate is also very good.
