I can also say that I have 10 Jiao, 100 Fen, 1000 Li, 10000 milli, 100000 silk, 1000000 Hu, 10000000 micro. No matter what the unit of measurement is, I will neither become richer nor buy more, nor have any impact on the economy.
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
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
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

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 />
this is also the first transaction between bitcoin and physical object I know.
it is understood that because bitcoin trading is not under the supervision system of banks, it is easy to be used in illegal activities, such as money laundering and drug purchase
at present, most countries, including China, have no clear attitude towards bitcoin regulation, except that Germany has made it clear that bitcoin is legalized and Canada has created the first bitcoin ATM. At present, there is still a lack of supervision on bitcoin in China, and the existing laws and regulations are not fully applicable to the supervision of bitcoin
e to the uncertainty of policy, some people in the instry are worried that every time the regulatory authorities take action, the price of bitcoin will fluctuate sharply, and there are risks in future hedging
2. The practical value of bitcoin is not high
the future development prospect of bitcoin largely depends on whether its payment function can be well reflected. Zhang Yuewen, a researcher at the Financial Research Institute of the Chinese Academy of Social Sciences, previously said that bitcoin does not play the core function of money payment, but only exists as an investment proct. If one day bitcoin can't be exchanged with the major currencies in circulation in the real world, it's worth less than a piece of waste paper
3, trading platform run away
however, bitcoin trading website is very fragile, the website may be attacked by hackers or shut down by competent authorities, and website operators may also run away with money, which may cause losses to the holders. At the end of October 2013, GBL, a trading website that was once popular in the bitcoin circle, suddenly shut down. Before most users had time to withdraw the funds from their accounts, GBL had already run away. According to incomplete statistics, there are about 500 victims, and the estimated loss may exceed 20 million yuan< 4. Control environmental risk
you also have to consider the environmental factors. Mining machinery is not a zero emission equipment, which will create a lot of noise and heat. In this way, you have to consider the physical and mental health of the operation workers, and you also have to consider the relationship between the surrounding residents. If you dare to build a mine of a certain scale in the community, the neighbors will certainly demolish it for you, unless you are a local tyrant< 5. Control technology risk. Bitcoin mining is mainly a technical problem in engineering, but the professional technology of bitcoin itself is not the key. You need project management talents, electricians, construction engineers and computer room construction talents. Although this knowledge is not complicated, experienced people can help you rece costs and control risks
is there any risk in investing in bitcoin? Bitcoin is very close to Ponzi scheme; Bitcoin has no price limit, and its market has always been like a roller coaster. The early recipients of bitcoin have a great advantage. If the follow-up funds stop entering this field, bitcoin cannot continue to appreciate. We should not be blindly confident, let alone gambling.
