Kidnappers want digital currency

1.

Invisible bitcoin can not only make people rich or poor overnight, but also bring people worry about their lives

According to Ukrainian media reports quoted by the daily telegraph, on Tuesday (December 26), Pavel Lerner, CEO of the British bitcoin exchange exmo, was kidnapped after leaving his office in Kiev, Ukraine, and dragged into a black galloping car by a group of masked people

after the above news came out, a spokesperson of exmo told the daily telegraph that we are doing our best to speed up the search for Lerner and welcome all clues from the outside world. Exmo's business is running as usual and all users' funds are absolutely safe. According to the company's official website, the platform has more than 900000 users

after the kidnapping incident attracted public attention, exmo also announced on official twitter on Thursday that it had been attacked by DDoS (distributed denial of service) with the intention of destroying platform transactions

according to Wall Street reports, at the beginning of this month, when bitcoin rose to more than US $13000, the payment system of nice hash, the world's largest digital currency mining platform, was hacked and bitcoin in users' wallets was stolen. Bitcoin millionaire, a bitcoin information website, has since estimated that as many as 4736 bitcoins were stolen by hackers, with a total value of more than $62 million

interestingly, as a foreign netizen imagined, after the kidnappers received the ransom, if bitcoin continued to appreciate, it would be OK. If bitcoin collapsed before the gloves turned, wouldn't it be a "huge loss"

In fact, this is also the old question in the minds of many investors - how long can bitcoin's investment boom last

On December 2, when talking about bitcoin in public activities, pan Gongsheng, vice governor of the people's Bank of China, said that it was a decisive and correct decision for regulators to shut down bitcoin trading platform and stop ICO a few months ago

According to BBC news, on December 14, Andrew Bailey, CEO of the financial conct authority (FCA), the UK's top regulator, issued a warning to investors, saying that bitcoin buyers should be ready for "full compensation". Bitcoin lacks the endorsement and support of the government and the central bank, and its risk level is the same as gambling, he said

on Thursday (December 28), the South Korean government announced the countermeasures to combat virtual currency speculation, and considered closing some virtual currency transactions, so as to curb excessive speculation. In addition, the South Korean government has decided to implement the real name system of virtual currency trading and expand the investigation authority of the Fair Trade Commission, the anti-monopoly law enforcement agency

In a statement, the South Korean government said that cryptocurrency speculation in South Korea has gone too far and has become irrational, according to the report. The government can no longer allow abnormal speculation to develop

the Indian authorities also issued a warning. On Friday, India's finance ministry warned investors about the risks of cryptocurrencies such as bitcoin, saying digital currency investments look like a Ponzi scheme, Reuters reported. In a statement, India's Ministry of Finance said investors and other participants in digital currency transactions were "entirely at their own risk" and advised that it was best to avoid such investments

but from the perspective of optimists, bitcoin is not as static as gold. As a virtual currency, its software code is constantly developing, and its functions can be constantly adjusted, improved and updated, and its value can be realized in unimaginable ways, such as, Many bitcoin fans are looking forward to bitcoin's "lightning network" (an improved way to facilitate payment). If bitcoin gets more attractive functions in the process of continuous evolution, people can even use it for convenient and fast cross-border payment

according to China Securities Journal, based on the sustainability of bitcoin development, bitcoin supporters believe that even if the market value of cryptocurrency expands to 20 times the current value, the market will not go crazy. However, as far as bitcoin itself is concerned, with more and more new technologies coming out, bitcoin's share in the cryptocurrency market will show a downward trend in the future

Hong shuning, a senior researcher of Suning Institute of financial research, recently wrote an article, imagining two situations of "truly killing bitcoin":

first, all bitcoin development teams are conservative and complacent, no longer absorbing the latest scientific and technological achievements to improve themselves, resulting in the emergence of a new digital currency with all aspects of technical indicators exceeding bitcoin, It is widely accepted by the society and then replaces bitcoin. This is the failure of bitcoin, but also the success of virtual digital currency

Second, there are serious loopholes in the bitcoin protocol or wallet software, which lead to the security of the whole bitcoin system can not be guaranteed, a large area of funds are stolen, sold at a low price and uncontrollable in the short term, and the social confidence in bitcoin is completely lost

so. In this world, money is easy to use

P: present value, the amount converted from a certain amount of money at a certain point in the future to the current amount&# 8194; The present value (principal) and the final value (sum of principal and interest) are the corresponding values of a certain amount of money at different time points, and the difference is the time value of money

The principal is the present value, the sum of principal and interest is the final value, and the interest rate I is the time value of money

1. final value of compound interest; F=P(1+i)n ，( 1 + I) n is the final value coefficient of compound interest, denoted as (F / P, I, n)

2. 2 present value of compound interest; P=F/1+in ， 1 / (1 + I) n is the present value coefficient of compound interest, recorded as (P / F, I, n)&# 8194;

   Conclusion: &
   The final value and present value of compound interest are inverse operations&# 8194;
   (1 + I) n and 1 / (1 + I) n are reciprocal 1
   The definition of the time value of money: from the perspective of quantity, the time value of money is the social average profit rate without risk and inflation. When measuring the time value of money, risk reward and inflation factors should not be included

   the time value of money refers to the added value of money after a certain period of investment and reinvestment, which is called the time value of capital. The time value of money does not come from the field of proction and manufacture, but from the field of social capital circulation

5. Whether it's cleaning houses for others, cooking or repairing cars, you can get a "time coin" for every hour you work
time currency can not be directly converted into RMB. You can only let others work for you through time currency
sometimes, time coins are of great use. Let me give you an example:
Maria villacresses, 28, lives in allenton, Pennsylvania. When preparing for the wedding, she was in trouble for lack of money, so she turned to a local time bank called "community exchange". She gets "time coins" by working as a medical translator and taking care of pets, and then exchanges these "time coins" for the wedding
on the wedding day, the cosmetics salesman, who is also a customer of "time bank", painted her bridal makeup, and the cake maker sent her a 7-story wedding cake. The wedding cost about 200 "time coins", which saved her about $2000
time bank brings them a lot of valuable added value, such as helping others broaden their interpersonal relationship, improve their relationship with neighbors, strengthen their community awareness, and learn a lot of skills. Different from barter, the transaction of time bank is not always equivalent exchange, and not only benefits both parties. Here, Joan takes care of John's children, John repairs Mary's faucet, and Mary gives Tom a free ride... Although everyone's labor intensity is different, they get the same time coin per hour, and people don't care whether the payment and reward are equal

6. A million yuan in cash is not very heavy. Well, a girl should be able to ask questions

7.

The kidnapper asked for a ransom of 500000 yuan, and the mother cut it to 33000 yuan. The reason why the kidnappers are so easy to talk is that they didn't take the mother's daughter hostage at all. They confused the mother with another girl's voice and made the mother very anxious. It is understood that the incident happened recently. The mother was also at work when she received a call from her daughter whose caller ID is her daughter. After receiving the call, a girl's voice came from the other end of the phone asking for help. Therefore, the mother was very anxious at this time. The so-called kidnapper on the other side of the phone said that she would pay a ransom of 500000 yuan, But also because the mother's family conditions were not very good, so she couldn't get the 500000 yuan at all, so the mother also told the so-called kidnapper on the phone{ RRRRR}

therefore, to sum up, the kidnapper asked for a ransom of 500000, and the mother cut it to 33000. The reason why the kidnappers are so talkative is that they did not take the mother's daughter
