bitcoin is a kind of electronic currency / network virtual currency
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
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
extended data:
currency features:
1, decentralization: bitcoin is the first distributed virtual currency, the whole network is composed of users, and there is no central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining: users can explore the computing power of different hardware on many platforms
advantages of bitcoin:
1, it is completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues. Its distribution and circulation are realized through open-source P2P algorithm
2, anonymity, tax exemption and supervision free
3, robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
4, borderless and cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
5, Shanzhai people are difficult to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency
but these counterfeit currencies are very fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency
many counterfeit coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
the weakness of bitcoin
1, the fragility of trading platform. 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
2, the transaction confirmation time is long. 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
3, 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
4, 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 distinguish 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

Bitcoin price accelerated to rise at the same time, there has been a more rapid decline in the callback
according to the price of coindesk on bitcoin news and information network, on January 11, the price of bitcoin fell to about US $30305, down 27.78% from the highest price of US $41962 in history. In other words, the price of bitcoin fell from $40000 to $30305 in just over a day. Before that, bitcoin took six days to rise from $30000 to $40000
from the macro-economic environment, Yu Jianing believes that the correction on January 11 can be regarded as a hedging measure taken by overseas mainstream investment institutions. He believes that one of the reasons for bitcoin's rise this year is the continued decline of the dollar index. At present, Biden's government is coming to power, "bad is good", the dollar may rebound, global commodity assets have a significant correction, and the digital asset market will adjust accordingly
in recent days, the US dollar index has risen significantly. As of press release, the US dollar index is about 90.49, down 0.06 from the previous day and up 1.16% from the closing price of 89.42 on January 6
he also pointed out that many bitcoin miners choose to sell at relatively high prices. According to cq.live, the miner's position index (MPI) has reached its highest level this year. The MPI index is higher than 2, which indicates that miners tend to sell bitcoin after mining; If MPI is negative, it indicates that they are optimistic about the short-term trend and choose to hoard bitcoin. At present, the value is about 5.26, indicating that the miners are selling bitcoin on the over-the-counter market or exchange. In addition, bytetree data also shows that in the past week, bitcoin miners g out 6894 bitcoins, but sold 10047 bitcoins, which means that the miners sold nearly 3153 bitcoins in stock
Yu Jianing mentioned that another reason for the decline is the website downtime of the largest compliance exchange in the United States, such as coinbase, after the market fluctuated violently, which delayed the trading of users, and many buying orders could not be traded normally, which also led to the bitcoin price on the website far lower than the market price, further aggravating the market panic
"e to the failure of the coinbase system, we could only sell but not hang up the bill yesterday, and the whole trading world order was destroyed." A coin circle employee also said
regulatory warning bitcoin volatility risk
it is worth noting that the recent ups and downs of bitcoin has also aroused the vigilance of regulatory authorities in various countries
On January 12, the New Zealand financial market authority (FMA) warned new Zealanders to invest in cryptocurrency prudently, according to the New Zealand Herald"new Zealanders who are considering buying cryptocurrencies such as bitcoin should realize that they are high-risk and highly volatile assets," a spokesman for the New Zealand Financial Markets Authority said. "Cryptocurrencies are not regulated in New Zealand and are often used by fraudsters and hackers."
According to the times on January 9, HSBC has decided to stop providing cryptocurrency trading services to customers in the UK, including prohibiting customers from depositing funds into HSBC from their digital wallets. At the same time, many other UK banks have banned customers from using credit cards to buy digital currencies such as bitcoin"the virtual currency represented by stable currency is facing more and more complicated compliance risks. As more and more economic activities migrate to the blockchain, the instry is facing great compliance pressure. The circulation of stable currencies such as usdt will grow explosively in 2020, reaching a record high. Behind this, part of the use demand comes from the normal transactions in compliance, but there are also black and gray demands for money laundering, illegal financing and other problems. In the future, the blockchain instry will face more and more compliance challenges. " Yu said
he pointed out that according to the report on anti money laundering of virtual currency released by peckshield in 2020, the value of unregulated outbound virtual currency reached US $17.5 billion in 2020, an increase of 51% compared with that in 2019, and it is still growing rapidly. The number of fraud cases involving virtual currency continued to rise to 151, an increase of 655% over 2019
Yu Jianing said: "since the second half of 2020, fraud, attack, extortion, gambling and other assets, as well as money laundering, run points and other gray assets, have begun to turn into virtual currency money laundering. The number of extortion cases has increased rapidly, and the situation of virtual currency anti money laundering is grim. In 2021, it is necessary for the blockchain and digital assets instry to adopt a more strict and prudent KYC (know your customer) review mechanism, More stringent anti money laundering standards will be implemented. "as far as I know, it was proposed by Fu Houjian, the legendary god of Amway
it's something that must be possessed in Amway business. It's not allowed to apply to other companies. Even within Amway employees, other system branches are not generally recognized
at the same time, the internal training routine of the system is: as long as you participate, no one will not graate
it's just a matter of personal qualification and chance to understand the deep meaning of the course and the way to success
although I don't know if you are going to engage in Amway business, from the experience I have participated in, for college graates who have no working experience, it's OK to experience if they have time
the reason is that its operation mechanism is similar to that of a regular company, which allows you to have some "feelings of employment" in advance
I always believe Chairman Mao's saying: "no investigation, no voice!"—— Therefore, "BTC" or "university courses" which is more helpful to find a job, only you can answer
- - - - - - - - - - - - - - - - - -
in terms of the current situation of ecation in China, schools basically only teach "book knowledge"
BTC should be regarded as a kind of professional quality ecation
- if you have this kind of quality, there is no practical value
- if you don't have this quality, maybe you can learn something from it?
According to
crypto cred, this situation may indicate that there is not enough momentum to do long in the market
in addition, crypto cred also believes that the consolidation of bitcoin in the previous three months is a range consolidation, not a triangle consolidation, so once the horizontal support line is broken, the market sentiment will become very pessimistic
crypto cred also pointed out that in the daily K-line chart of bitcoin in September, the closing price of 24 days was lower than that of the previous day, which also showed that the whole trend was developing in a bad direction
Future trend, how to develop< p> Ledger status points out that bitcoin's stepping back into the $8000 or even lower range is likely to prepare for future actionshe believes that bulls need to take back several key positions first. First, bitcoin needs to go back above $8400, which is the 200 day moving average
he explained that if the price of bitcoin could get back to $8400, it could rise rapidly and retest $9400. After that, if bitcoin can further break through the previous integration range, it is very likely to create a new annual high
However, unfortunately, the 200 day moving average is becoming a strong resistance line. If bitcoin fails to break through this position, it is likely to go further down to the low of $6000however, ledger status also points out that even if bitcoin goes further down to $6000, technically speaking, the long-term bullish trend has not been broken. He said,
"I remain bullish for a long time, unless bitcoin falls below its 200 week moving average (currently about $4600 and is still climbing), which marks the bottom of the first two bear markets."
finally, ledger status said that if the price of bitcoin can rebound above the 200 day and 20 week moving average, it will be quite optimistic for the market
up to now, the price of bitcoin is US $8070.5, and the market value of bitcoin accounts for about 67.1% of the total market value of the whole cryptocurrency
Original long short Hunter investment on March 15, 2018
recently, through communication with you, Ango learned that many investors in the currency circle are more concerned about where bitcoin will fall and when it will be able to bottom out
since we are concerned about when we can buy the bottom, that is to say, in the current downward trend of the currency market, many investors are relatively rational. In the context of confusion, they don't have heavy positions, or even go to Soha with full positions
I'm afraid no one will believe the question of when the currency market will bear. No one can guess the bottom. The market will graally stabilize only when most people are not optimistic
As for which area to fall to, there is no solutionwe use rational thinking to analyze the market in recent months. In the bear market, the short market can be divided into three cycle stages:
the first stage is the "shipping" cycle, and its real formation is in the last stage of the previous bull market. Maybe far sighted investors in the currency circle will realize that the amplitude of currency price in this range is also much larger
according to the trend of daily line level, the next level of support will be in the $6960 area. After a large number of buying chips are released in the callback, you can pay attention to whether there are opportunities for short-term participation
BCH
bitcash has officially entered the short market area since the middle of January, and the medium-term trend has been downward. The short-term demand to stop the decline remains to be seen
under the premise that the market as a whole is weak, even if we want to participate, there are only short-term band opportunities. We should develop the habit of closing up when we see the good. After all, the market environment has changed, so we need to be more cautious
the support level below the currency price can focus on the $670 area
eth
the important support level of the area below the etheric currency is around us $490, and opportunities are falling out. Before it stabilizes, it is still mainly to wait and see
now that the real bottom is in that range, it doesn't matter any more
what we can do is to try our best to absorb chips with lower prices
