First of all, we need to understand what is MLM:
MLM refers to the illegal behavior of organizers and development personnel to obtain wealth by calculating and paying remuneration to the developed personnel based on the number or performance of the personnel directly or indirectly developed, or requiring the developed personnel to pay certain fees to obtain the qualification to join. The essence of MLM is "Ponzi scheme", that is to say, the money of later comers is distributed to the income of former comers
However, the new type of MLM does not restrict personal freedom, does not accept ID cards and mobile phones, and does not take classes collectively. Instead, it uses capital operation as a banner to pull people to cheat money, drives luxury cars, wears gold and silver, and uses money to attract your relatives and friends to join in, and finally makes you lose all your moneythen judge whether the ether coin is a kind of MLM, whether you need membership fee, whether you need to ask your relatives and friends to join
extended materials:
Ethereum is an underlying technology platform on which developers can create distributed applications. With the application, there will be transactions. With a transaction, you need money to complete the transaction. In this way, money has value, and investors' investment has a return. If the transaction volume on the platform is larger and larger, the demand for money will be higher and higher, and the money will be more and more valuable
from the perspective of image, bitcoin creates a kind of digital gold, while Ethereum creates a country, and Ethereum is the credit currency of the country
after bitcoin, there are thousands of digital virtual currencies in the world, many of which are completely deceptive in the guise of "digital currency". Previously, Haikou Municipal Public Security cracked down on a pyramid selling organization called "Eurasian currency", which operated on the internet pyramid selling platform, making more than 40000 investors cheated, involving 4.06 billion yuan. The field of virtual currency has just started, so we need to be cautious

In the past year, the number of cryptocurrencies has been growing rapidly, including bitcoin led cryptocurrencies focusing on payment and Ethereum led functional cryptocurrencies focusing on infrastructure. No matter what kind of cryptocurrency you are optimistic about, the most important thing you are concerned about is the rise of the currency price. However, in the process of many currency price rises and falls, the most important thing is the rise of the currency price, There is a type of cryptocurrency that is most sought after by investors. That is the trading points launched inside the trading platform, which is also known as platform currency
the BC points of bgj.io, the money manager, will be sold to the public from May 3, with a total amount of 60 million pieces and a daily quota of 8 million pieces for seven days. The sales of 300000 pieces in a single account will be limited. As of May 9, all of them have been snapped up. It can be seen that money friends are very optimistic about the points of this platform. I believe every senior investor has heard or experienced the grand competition of HT. On January 26, the amount of ht28.56 million was robbed in 32 seconds! The players who get it are jubilant, while those who don't get it are dejected. Why are platform points so popular? In fact, it's very simple. Just refer to coin an's BNB. According to the data of coin market cap platform, the global average price of BNB at the beginning of its issuance was US $0.1, which rose to US $2.6 in less than a month, up 26 times! In addition to the currency price income, the platform will also give fixed dividend income to the platform currency holders. Take coin an as an example, the daily dividend of coin an is as high as more than 20 million yuan. However, when these well-known platform currencies rise to the present, it is not meaningful to buy them again, because the space for currency price rise is extremely limited. Today, Xiaobian will dig out a high-quality platform currency and exchange for you - currency Manager (bgJ. IO) and platform integral BC (guanjiayuan), so as to give you more investment options
Xiaobian learned about the exchange because the platform recently launched its own platform, coin BC. As a "steady" old leek, he is very interested in the platform points launched by various exchanges. After a detailed understanding of the exchange, he thinks that the platform has great potential, In particular, the sales and dividend model of the platform's points make Xiaobian's eyes bright. The following Xiaobian lists several highlights of the exchange based on the information she inquires, so that investors can judge the pros and cons by themselves
the first bright spot: the steady growth of user volume
as a blockchain asset trading platform, coin housekeeper was officially launched in March. Although the launch time was short, coin housekeeper has accumulated hundreds of thousands of users in more than one month. And it is understood that the daily growth of money manager's user registration is stable at 70% - 85%. In such a competitive situation of the exchange, it is not easy for a new exchange to have such a large number of user growth in a short time, which is enough to show that the trading platform has at least achieved the ultimate in user experience<
the second bright spot: the highest platform bonus in all exchanges
money manager recently launched the platform bonus BC (family currency), with a total issue of 200 million pieces (never increasing), of which 100 million pieces were locked for one to three years, and released in batches in three years after the platform was launched for one year. In order to ensure the currency deflation, the platform promised that after the platform was launched for one year, Every quarter, 20% of the profit will be used for BC repurchase to ensure that there will be no more than 100 million pcs in the market, which is similar to coin an's BNB
the biggest difference between BC and BNB is that all users holding BC will participate in the dividend except for the locking part of the platform, and the dividend proportion is 80% of the monthly transaction fee profit of the platform! According to the announcement of the platform, this substantial profit transfer is in the hope that the whole people will hold shares and jointly promote the development of money management. And in the later dividend process, adjust the dividend date at any time according to the number of users and profit status, and carry out dividend every week or every day. Coin an's daily dividend can be as high as more than 20 million. Over time, the daily dividend amount of BC, which has the largest dividend strength, should be more exaggerated
the third bright spot: BC's unlimited rising space
no matter what kind of platform currency, there are few on-line currencies that don't rise, and they all soar, which is a tacit fact in the currency circle, because platform currency reflects the strength and reputation of an exchange. BNB (currency security currency), at the beginning of its launch, was US $0.1, only 10 months after it was launched, with a maximum increase of 245 times. At present, the currency price is US $13.76, even though it has dropped a lot, it has also increased 138 times compared with the original
the development path of BC is similar to BNB in many aspects, including the amount of currency issued and the quarterly repurchase ratio. The only difference is that BC has greater dividend strength and is more friendly to ordinary investors
for users, they can pay transaction fees and enjoy a certain discount after purchasing BC. In addition, you can give priority to experience some new functions and have exclusive activities. With the continuous expansion of money manager business, BC will also undertake the function of legal money circulation. Users with BC can purchase cryptocurrency without handling charge and without the influence of block confirmation speed, and further enjoy platform dividends and share platform profits
in a word, whether BC can rise or not depends on the earning power of money manager platform. Money manager can stand out from many competitors and maintain stable user growth every day, relying on good user experience, excellent exchange currency, professional and responsible customer service attitude and maximum dividend mode. With the increase of transaction volume and profit of money manager platform, there is no doubt that BC will rise in the future. According to the current development trend of money manager, 100 times BC is not impossible
first, smart contracts are so good that they are not useless
smart contracts. As the name suggests, smart contracts refer to contracts that can be executed automatically by computer code; Ethereum virtual machine is used to execute smart contract; Smart account is the carrier that smart contract can be executed. In other words, smart account, this "account" can be controlled by Ethereum virtual machine. According to what control, according to smart contract
there is no free lunch in the world. The smart contract function is so good that it's not useless. When you trade in Ethereum, you have to pay the miner's handling charge. So what's the handling charge you have to pay on Ethereum system, and what's the relationship between
gas and handling charge
2. What's the matter with Ethereum gas
Ethereum gas is similar to automobile fuel. It needs Ethereum gas to drive smart contract. Gas is an English word, Chinese meaning: gas, gasoline, this thing in daily life, is a consumable. Why does Ethereum proce fuel
what is the meaning of gas in Ethereum? In fact, Ethereum's gas is closely related to transaction costs. Ethereum transaction needs service charge. This gas is the calculation mode of service charge of Ethereum
in the setting of Ethereum, the transaction fee is similar to an encrypted fuel, namely gas, which can drive the movement of smart contracts. When Ethereum executes transactions on the blockchain, the fuel will be graally consumed according to the rules of the characteristics
from this point of view, gas is really the same as its original intention, like automobile fuel. If you want to start a car, you must need fuel
What is the difference between the transaction fees of Ethereum gas and bitcoin When it comes to handling charges, you may be familiar with them. There is no free lunch in the world. Both Ethereum and bitcoin need service charge, but the service charge mode of the two is different. Bitcoin is used to pay bitcoin as a transfer fee directly, but Ethereum is not In essence, Ethereum is a virtual machine, which is decentralized and controlled by people all over the world, forming a "world-class computing network". When you send a token, execute a contract, transfer Ethereum, or do other things on the block, the computer needs to calculate when processing the transaction, which consumes network resources. In this way, you have to pay the "gas" to get the computer to work for you and the miners to process the transaction for yougenerally, the higher the gas price the sender is willing to pay, the greater the value the miners get from the transaction, and the more likely the miners are to choose the transaction. In this way, miners are free to choose to trade. In order to set the gas price for the sender as a reference, miners can directly put forward the lowest gas price they need to execute the transaction
How to calculate the gas consumption of Ethereumwhen Ethereum virtual machine processes transactions, Virtual Opportunities process one by one according to the operation instructions determined in the transaction, and each operation instruction has a specified gas consumption
Ethereum system stipulates two accounts: one is normal account and the other is smart account
for ordinary transfer transaction, that is to call "normal account", the required gas is fixed 21000
when calling "smart account", because the complexity of smart contract is different, the required gas is also different. The more resources (computation, memory, etc.) used to process transactions, the more gas will be needed. For example, an addition operation will consume 3gas. If more complex operations are performed, the more gas will be consumed
then you may ask a question: when a user's transaction involves a malicious smart contract, the contract is extremely complex, and the execution of the contract will consume unlimited fuel, what should we do? The solution of Ethereum system is: in order to avoid unlimited gas consumption caused by malicious
smart contract, the user needs to set the maximum allowable fuel consumption when sending the transaction, namely
gaslimit. In this way, even if there is a malicious smart contract, the worst case is only within the fuel consumption range specified by gaslimit
What is the relationship between Ethereum gas and transaction feeson Ethereum, the service charge you pay is equal to gasprice times gasused
you can understand gasprice as the unit price of fuel and gasused as how many liters of fuel the car needs
for a car, if you say 20 yuan per liter of gasoline, 10000 liters of gasoline is 200000 yuan. For Ethereum, each
gas is 20 gigabytes (gigabytes is the unit of quantity of Ethereum currency), and 10000 gas is: 20 times 10000 equals 200000 gigabytes, 20000 gigabytes equals 0.0002 Ethereum, that is to say, the transaction procere is 0.0002 Ethereum
the specific exchange value is shown in the following table:
for specific exchange rate query, you can check the following website:
for details https://jin10086.github.io/etherconVerter/
both gas price and ether price are freely regulated by the market, but they are different in that the price of ether fluctuates according to the market situation, while the price of gas is determined by miners, If the price of fuel falls below the miners' minimum requirements, the miners refuse to process the deal. The separation of gas and Ethereum can protect the system from the possible fluctuation with the rapid change of Ethereum price
generally speaking, most miners will choose to give priority to their interests. When dealing with the transaction, they will arrange according to the gas price from high to low, and give priority to those with high gas price. If you are in a hurry to trade, you need to raise the gas price so that the miners can see you earlier; If you are not in a hurry, you just need to set a gas price, which is above the bottom line of gas price set by miners
How is gas obtainedin fact, gas is the ether coin purchased from the miner. The ether coin in the user's own account can purchase gas from the miner, and the Ethereum client will automatically purchase gas with Ethereum according to the specified maximum transaction expenditure limit
Where did gas go in the endfor each transaction, the initiator of the transaction must set the gas limit and gas price. Different operations will proce different gas costs. When the gas is used up, the miner will stop executing, and the gas used will be used as a reward to the miner. This will involve several situations:
the first situation is that if there is a surplus gas, the miner will stop executing, Then the remaining gas will be returned to the transaction initiator or the creator of the smart contract. For example, if I send an Ethereum to Yiyi, the gas limit I set is 50000, and the gas normally consumed is 21000, then the remaining 29000 that has not been consumed will be returned to me
in the second case, if the gas limit I set is too low, or the Ethereum in my account is not enough to pay for my gas consumption, then the transaction will be cancelled e to insufficient gas, and the gas used for calculation will not be returned to my account
in the third case, if the transaction fails, I have to pay the handling charge for the occupied computing resources
How to set a reasonable gas pricebefore each transaction, you can query this website to confirm the gas price to be set: https://ethGasstation.info/ To sum up, in this article, we mainly introce the gas and service charge of Ethereum: gas is equivalent to fuel oil. When you process transactions on Ethereum virtual machine, you will consume computing resources, that is, gas. On Ethereum, the service charge you pay is equal to gasprice multiplied by gasused, that is, the unit price of gas multiplied by the total amount of gas consumed. The complexity of the operation is different, and the cost of gas is also different. When the gas is used up, the miner will stop executing, and the gas used will be used as a reward to the miner. The miner will give priority to the trader with higher gas price
if you really love someone, that person will appear in your heart when you want to forget most, and will appear in your heart when you are sad and lost most, But you think about it again and again, but you can't be sure whether you want to tell him how you feel now, your current distress, because
according to the report, Zhejiang blockchain government platform is mainly engaged in blockchain bills, especially medical bills. The public platform of Changsha's SMIC blockchain mainly focuses on government information disclosure, government affairs handling, intellectual property protection, judicial expertise, finance and so on, but it has not involved the medical bills yet.
