What are the disadvantages of bitcoin
bitcoin is a fraud, so we must be cautious in investment and financial management
even if it is called "hard currency", the price of gold will not only rise but not fall. There is no bubble in gold, but the price is too high, there is a bubble, and the bubble will eventually burst, such as virtual currency such as bitcoin. The more general virtual currencies, the closer bitcoin's value is to zero
this kind of currency, which is a purely calculated digital symbol, has no asset support, no financial revenue and expenditure, no cash reserve and no use value. It is only a circulation symbol. Once it loses its credit guarantee, it is a pile of beautiful printed waste paper. Investors should be alert that there is no so-called safe investment in this world, and all investments are risky
the people's Bank of China and other departments issued a document to severely punish the above-mentioned behaviors, making it clear that token trading is not protected by law. With some virtual currency trading platforms turning to overseas, speculative money speculation has also turned to "underground". In the face of continuous renovation, on the basis of continuous strict supervision, government departments should constantly upgrade the means and ability of supervision, and continue to increase publicity and crackdown on popular science, so as to avoid the masses being deceived
extended information:
investing in virtual currency is more of a kind of speculation. Investors should strengthen their risk prevention awareness and identification ability. Without confirming the identity of the other party, they should not be involved in money transactions, trust low-risk and high return investment procts, especially not join the investment and financing group without verification, These are often well-designed traps by telecommunication network fraudsters
it's better to purchase the investment and financial management accompanied by the children, and learn from the official and authoritative channels, and report to the police in time when they are found to be cheated. Properly protect all kinds of account password, identity information, etc., don't tell others easily. Any reference to the need for transfer and remittance should arouse high vigilance and consult with trusted acquaintances

Chinese players have become the main crowd in buying bitcoin, which has directly led to the popularity of Chinese bitcoin trading websites. Even the laurel of "the world's largest trading platform" has rotated among bitcoin trading websites in China. What are the disadvantages of bitcoin
the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
bitcoin has been given a mysterious color since its birth: it is said that because of its concealment and limitation, it is used in drug trafficking. With this kind of dark color, it was packaged as a financial proct and successfully started trading. Many people wonder if bitcoin will eventually replace money? It is not issued by any institution or country, is not controlled by any organization, and is completely decentralized. Bitcoin instead of currency can avoid currency being artificially controlled. However, while this idea sounds wonderful, it cannot be realized
the transaction of bitcoin has congenital defects, and the transaction of bitcoin is irreversible. In other words, it can never be undone: once confirmed, there will be no "error" and no "return". This will bring great inconvenience to the transaction. The limitation of bitcoin also determines that it can not meet the needs of transaction< br />
system version: MacOS
10.12.1
(16b2657)
if your system version is less than 10.12.1, Please check the update and install it through app
store (or download the combined update installation image from Apple support website for manual installation). If you have installed 10.12.1 but the version number is less than 16b26xx, it means that the 10.12.1 you installed is not the latest version. You need to download the combined update installation image from Apple support website for manual installation
MacOS
10.12.1
update content: https://support.apple.com/zh-cn/ht206174
MacOS
10.12.1

2. To enable the native touch
bar function, you need to use your apple
ID to download Xcode from the app
store (about 15g of disk free space, if you are the developer of MacOS or IOS, Congratulations, you can continue). After installation, open Xcode and select
window show
touch
bar from the menu of Xcode at the top of the screen, You will find that the touch
bar is already displayed on the screen. At this time, you just need to keep Xcode on (which can be minimized). You can experience and use touch
bar as much as you want. Just like the entity touch
bar, you can open the system preferences app, customize your touch
bar display mode in the "keyboard" item, and also customize the buttons on the control bar. You can even choose display custom multi touch
bar from the menu of apps that support custom touch
bar to customize the application control bar. Yes, you now have the full function of touch
bar. The only difference is that touch
bar is directly displayed on the screen. Of course, you have to use the touch pad or mouse instead of touch and click. Finally, you need to find a suitable location for the touch
bar window on the screen
3. Another scenario: if I am an ordinary user and do not want to download Xcode, or the available disk space is not so large, can I not experience touch
bar
of course not. If you can't turn on this function directly, there will always be a big God who can transplant the function to make it run independently. Download a file called
touch é
app
note: the system should refer to point 1, otherwise it will not work. On the other hand, although the two look similar, Xcode turns on calling the native functions of the system,
touch é
it is the version transplanted by Dashen, and its reliability may be slightly poor. You can check the update from time to time to see if there is any repair or improvement (you can also turn on the automatic update function)
finally, of course, there is still a gap between the experience and the entity touch
bar, such as the lack of the function of word selection and association when inputting Chinese. Emoj can only choose the most commonly used one. If you want to have a perfect experience, you are recommended to use a touch
bar device.
In fact, blockchain has been developing at a high speed since its emergence. Bitcoin, as a derivative of blockchain, is also the ancestor of all virtual currencies, and its value is very high
now there are only two ways to get bitcoin, one is to buy it, the other is to use ha Yu miner Mining! I believe the value of bitcoin will be the highest in the future
