Half a bitcoin

1.

There are only 21 million bitcoins

"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations

{rrrrrrr}

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. 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 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

Based on these two situations, price fluctuation seems to occur within 18 months after each halving. However, the data is still insufficient for proper analysis and price forecasting model

Will history repeat itself< p> It is important to note that in terms of the number of bitcoin holders, market value, regulations and the overall outlook for cryptocurrency, there are huge differences between 2012, 2016 and 2020. For example:

market value: November 2016 - & gt; $11 billion, December 2019 - $132 billion

daily trading volume: November 2016 - & gt; 84 million US dollars, December 2019 - 17 billion US dollars

e to the increased public awareness of bitcoin and the interest of institutional investors, the risk is higher this time. Although many other cryptocurrencies have been introced since 2016, BTC's dominant position is still 66.6%. As a result, the bitcoin miner is unlikely to switch to other coins, which means that halving may have a long-term impact on bitcoin prices

However, the main gain is that there is a certain correlation between the halving of bitcoin reward and the price fluctuation after the event. These supply changes happen every four years, and it's interesting to watch their impact on the price of the bitcoin

if it's transferred to your bitcoin wallet, if you don't save your private key, it's almost impossible to get it back

if it is saved in the website account, as long as you can find the website and go to retrieve the password to login, it is still possible to retrieve it

make sure you remember the website first. If you can't remember, it's useless to say anything< br />

4. The purchase of bitcoin can be based on 0.001, and you can buy as much money as you like.

5.

From the current technology, the next bitcoin in the bitcoin data structure can be divided into 8 decimal places, so the minimum unit of bitcoin is 0.00000001btc, but the transaction can not be so small

according to the statistics of bitbao, at present, the common minimum trading unit of bitcoin trading platform in China is 0.01btc, so the 0.0001 proposed by the owner is not available for sale< br />

6. Because you have no money

7. Who can give me two pizzas in bitcoin

8. The total number of bitcoin is 21 million. It was g up in 2140, and the mining speed has been halved in four years. At present, more than 13 million bitcoins have been mined. Bitcoin was invented by a man named Nakamoto, who disappeared in the bitcoin circle after 2010. No one knows who this person is

bitcoin is used for graphics card mining. It used to be OK, but now there is almost no profit from using graphics card mining. Of course, if your electricity is free, it's OK. The graphics card mining you mentioned is the second stage of bitcoin mining. The first stage is mining with CPU, which is an ordinary computer. The second stage is the graphics card mining you mentioned, commonly known as burning graphics card. At present, it has entered the third stage of ASIC mining machine mining stage. In this stage, the computing power is very high, the mining income is very low, and the mining cost is almost close to or even more than the currency price. At present, the profit of large-scale mining mainly depends on the energy consumption of mining machine and the advantage of electricity price.
