Bitcoin 15 minutes
bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

Yes, very much
let's take an example:
get up a little hungry in the morning and go out to buy a pancake to eat
the pancake seller said: 0.000001 bitcoin, please pay
You say: OK. 0.000001 bitcoin has been paid, please confirm After1 minute: please confirm
After2 minutes: please confirm
After3 minutes: please confirm
After10 minutes: please confirm
As a result, the boss finally confirmedjust now, because your blockchain fork is confirmed to be invalid, the transaction was unsuccessful. Please pay 0.000001 bitcoin again
you said: mlgb, it's too hard. But I have already eaten it. I can't help it. Pay again. Please confirm
After1 minute: please confirm
After2 minutes: please confirm
After3 minutes: please confirm
After10 minutes: please confirm
As a result, the boss finally confirmedjust now, because your blockchain fork is confirmed to be invalid, the transaction was unsuccessful. Please pay 0.000001 bitcoin again
you say: boss, I'm wrong. Shall I spit out the pancakes for you
So it can't be used At present, everyone is short selling Write an article tomorrow and tell us about it. See my blog: Tech help - Xiaocui says blockchain: how does bitcoin's Curse of wealth justify itselfIn such a case, most retail investors are sure to be able to do what they can or can't do. There is no other way, so they can only hope to see if they can slow down
according to some platform regulations, the loss of the platform caused by the failure of the user's forced flat order to close in time is through position. When the through position occurs, the platform will give priority to using part of the risk reserve to make up for its own loss , and the rest needs to be apportioned by all users of the current week according to a certain proportion to make up for the loss of the platform
I think this is more serious than the loss, but it should have little impact on our real currency. Because the two are not related . The currency of the virtual world is a game created by capitalists in order to converge the wealth of people in the real world. But no matter how we ordinary people speculate, we can't change the fate of these capitalists. They often dominate the changes in the war situation, turning their hands into clouds and covering their hands with rain. But no matter what they do, it should have little impact on the real world currency, otherwise governments will not allow them to exist
Therefore, changes in the bitcoin market will not affect the value of our real currency or other aspects. Even if there is, the governments of various countries will also vigorously suppress and try to rece the impact in this regard, so we should relax our mindbitcoin mining is a distributed consensus system that includes the transaction data to be confirmed into the block chain to complete the confirmation of these transactions. By mining, the data in the block chain can be stored in chronological order, the neutrality of bitcoin network can be maintained, and different computers on the bitcoin network are allowed to agree on the system state. To be confirmed, a transaction must be packaged into a block that complies with very strict cryptographic rules and verified through bitcoin network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid. Mining is as difficult as winning the lottery. No one can easily and continuously add new blocks to the block chain. Therefore, no one can control what content is included in the block chain or replace part of the content in the block chain to rece their cost. At present, bitcoin mining needs a professional Avalon miner.
How do you define gambling? If it's legal, investing in bitcoin is not a gamble. Investing in bitcoin is as legal as investing in stocks and futures, and the price of bitcoin is no longer as crazy as it was a few years ago. Just pay attention to the risk when speculating
I think the vast majority of bitcoin's 800 million yuan should have gone into the pockets of some capitalists, and the remaining few went into the hands of those investors who speculated correctly in my opinion, bitcoin is more like a bubble economy. It is a game between capitalists and capitalists. Because even if the bubble breaks, they have plenty of means to come out, but for us, these small shareholders are different. p> Therefore, as users, we still need to be more rational to look at these things. The sky won't drop pie for us to pick up. We still need to focus on the present. We can't always look down on those castles in the air< the most important thing is to do what you do now
first of all, I want to explain what this bitcoin is. Bitcoin is not a man-made coin, nor is it in circulation on the market. It is a virtual coin< with such a big drop in bitcoin, investors will surely suffer the biggest losses, and the futures and spot of investors will suffer double losses but in fact, it's really hard to say who can make a profit from it, because once bitcoin is sold, you will no longer own it. As for its later development, it has nothing to do with you, as long as you make a profit when you sell it
and according to the determination of relevant experts, there will be no winner after crossing positions and sharing losses. then it means that bitcoin suffered short sniping this time, which is a loss for those who have bitcoin, and no one can benefit from it< br />
Brother, I think you are worried too much. No matter how much bitcoin falls or rises, has little to do with the economic situation of our country. If it doesn't matter at all, it's not accurate. But because there are still some people in our country who play bitcoin, it must have a great impact on them, because their bitcoin has collapsed and their losses are relatively large< but it doesn't matter to the ordinary people in China, those who don't play bitcoin
and as non professional financial experts, or ordinary investors, they will not invest their eyes on bitcoin, so in general, this big burst of positions should not have much impact on our domestic market, and we need not worry about it
