I can't understand bitcoin

1. Definition: the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software is designed and released, and P2P network is built on it. Bitcoin is a kind of P2P form of digital currency, which is generated by a large number of calculations according to a specific algorithm. Bitcoin economy uses the 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 money circulation
generally speaking, bitcoin has the following properties:
1, no issuer. Bitcoin is a decentralized payment system that does not rely on specific monetary institutions
2, cannot be copied. The biggest difference between the computer world and nature is that nothing in the computer world can't be copied, but the peculiarity of bitcoin is that it can't be copied. If you give it to others, you will lose it
3, the quantity is limited. The total number will be permanently limited to 21 million
these three points are very similar to gold
4, it has no value in itself. Bitcoin has value only in circulation
this is similar to the currency issued by the government
5. There is no upper or lower limit for the daily rise or fall of bitcoin. Many investors have become rich overnight, and many people are destitute.
I think that as the general public, they only need to know these

2. Throughout history, there have been cases of gold, goods and even land confiscation in times of crisis. It is also disturbing that, as we have seen in Venezuela, people there are struggling with high inflation. Sometimes it is extremely difficult to convert money into another currency, which makes people feel helpless and can only watch their life savings be worthless. Bitcoin is very different. It is in electronic form and has no boundary restrictions. It can be transferred without any intermediary. Anyone who connects to a mobile device or the Internet can use it. All transactions are permanently recorded in the public ledger, and there is no dispute about ownership
in a recent article in the New York Times, a Venezuelan economist described how bitcoin became a part of Venezuela's daily life, so that on a mainstream bitcoin trading platform, Venezuela's trading volume ranked second only to Russia in the world. But bitcoin is not just used to protect wealth in extreme conditions. In general, bitcoin is also an excellent choice for portfolio diversification, and it should be seen as part of a comprehensive wealth preservation strategy.

3. If you download apps, you can download them directly from the app market, but some apps that have not been put on the shelves can be downloaded directly from the browser.

4. Hello, there is no weakness of bitcoin. 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

transaction confirmation takes a long time. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless.

The new generation of cahuang RTX 3080ti uses 5376 CUDAS, 384bit bit width, 12gb video memory, and the performance is 40% higher than 2080ti

for gamers, it's natural to pay attention to NVIDIA's geforce series of game graphics cards. It's revealed that the brand-new ampere graphics card will be an upgraded version of Turing GPU instead of the previously mentioned improved version. In other words, it's not just adding RT core to increase light tracking performance. At present, NVIDIA has upgraded DLSS to version 2.0, and the performance has been greatly improved compared with DLSS, The appearance of DLSS 3.0 makes the performance better, and the design principle of DLSS 3.0 has been greatly improved

in terms of performance, it is reported that the IPC of NVIDIA's ampere graphics card can be increased by 10-20%, and the L2 cache will be doubled. At the same time, 1900MHz will become the reference frequency, and the optical tracking unit in each group of SM units will be doubled. At the same time, the optical tracking unit will also have a performance improvement of 4 times. The most powerful rtxttan graphics card can even impact games with 8K resolution, but in the video memory, Due to the use of video memory compression, the video memory of RTX 3080 is 8GB, while that of RTX 3080 ti is 12gb, so the improvement is not great

6. First, the position management should be well arranged before trading; second, the selection of position building steps; third, the expectation of profit target; fourth, the treatment of loss expectation; fifth, the better trading mentality

7. Reason 1: the price of bitcoin tends to drop sharply from time to time. The market value of bitcoin (and other cryptocurrencies) has fallen by more than 80% Over time, though, prices have rebounded and hit record highs. But loss times are always brutal.

8. Well, you have so many questions

mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary. At present, mining is a very professional work, you need to buy a professional ASIC Avalon 3 generation miner for mining, and also need to join a mine pool

bitcoin is decentralized and not issued and controlled by any institution. Only bitcoin foundation is responsible for development and maintenance. The ore is free, but the equipment needs to be purchased. The exchange rate is high, which is a kind of trust in the bitcoin. It's a big social experiment. As long as you dig bitcoin, you won't worry about spending it. At present, thousands of businesses accept bitcoin around the world, such as the famous Dell company. There are also some businesses that accept bitcoin in China.

9. Bitcoin has no political risk at all in China. Money is essentially a commodity. If you have a commodity status, what else do you want
whether bitcoin is a currency is not based on the recognition of the government. The essence of money is consensus, and we all think it is money
China's law stipulates that RMB is the only legal accounting unit, and the circular issued by the central bank and other five ministries and commissions is also based on this legal principle. In China, gold is not recognized as a currency by law, and the US dollar cannot be used in China. But none of this hinders the value of gold and the dollar
the central bank and other five ministries and commissions are not trying to clean up bitcoin from the financial system, nor can they. They want to warn the public of the risks of investing in bitcoin, which is a politically correct approach, and any official institution is willing to do such a thing. Zhou Xiaochuan, the representative of the central bank, is happy to see the success of bitcoin. In late 2015 and early 2016, Zhou Xiaochuan accepted a lot of media interviews, claiming that the central bank is studying bitcoin and block technology, and disclosed that the central bank will issue its own digital currency.
