Contract crowdfunding virtual currency

1.

EOS: EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introced by EOS software, which aims to realize the performance expansion of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

The main features of

EOS are as follows:

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of blockchain, it supports multiple applications to run at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers. When you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value. To put it simply, if you have an EOS, it is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house. digital currency exchange "currency exchange"

development prospects

through a more in-depth understanding of EOS, EOS is quite valuable for investment. First of all, as the first to launch smart contracts, ETH runs smart contracts on eth, which is not free and depends on your gas. If gas runs out, the contract will stop. According to people who have used eth trading platform, it runs slowly and is very expensive, However, there is no such problem in EOS. The operation contract on EOS depends on the number of EOS you have. The more EOS you have, the more you can rent. With the continuous development, the more expensive the price will be; Secondly, it's very simple to develop DAPP on EOS, and you don't need to write many moles, because EOS itself builds the bottom mole for developers, which provides a platform and greatly reces the threshold of development; Thirdly, as an ordinary investor, owning EOS is equivalent to owning real estate, which can be used to rent and earn money. With the development of DAPP, the number of users increases, and the price increases irresistibly

4. Bitcoin (bitcoin: bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan.

5. Bitcoin is one of the most representative virtual currencies. A group of virtual currencies headed by bitcoin will exist for a long time. It will not replace the current legal currency. It will exist independently of the legal currency. It does not belong to any country. Some virtual currencies are reached by some people first, and then graally form a wider circulation because of its value, If more people reach this consensus, they will have the value of existence in the end. Of course, most of the virtual currency has no value, it is a kind of air currency. If a currency wants to exist for a long time, it must go through a long period of ups and downs, and constantly dig out its greater use value. Only in this way can it be a virtual currency with real value< There are two ways to invest in virtual currency:

first, mining is the only way to obtain some virtual currency such as bitcoin. After professional mining equipment is connected to the mine pool, bitcoin is obtained through a lot of calculation. Besides the cost of mining equipment, there is also the most important electricity cost. Mining machine is a computer, The required power consumption is not small, and the electricity cost needs to be continuously invested for a long time, so the mining income should be above the electricity cost, so the investment in mining is feasible. It can be divided into the following situations:

1. The cost of electricity is very low or electricity is free, there are some special instries that can enjoy lower electricity prices than ordinary residents, or build their own hydropower plants, etc...

2. The mining output is fixed. Friends who have g mines will know that one of the major obstacles in mining is the difficulty of computing power. Take bitcoin as an example, the number of bitcoins is fixed, but with more and more people digging, the output will be lower and lower, and then the income will be lower and lower. If the electricity cost is fixed, then when the output income is equal to the electricity cost, the output income will be lower and lower, Mining is no longer feasible

3. The currency price is stable. Mining will have the problem of accounting return to the current cycle: output * current currency price electricity cost = net income

mining machinery cost / net income = return to the current cycle

we mentioned that the output is fluctuating, and the currency price is also fluctuating, but we can choose to sell coins under the condition of our own income, which requires a large amount of personal reserved funds, Because once you choose to hoard money, it means that you will not generate revenue before the money price reaches the ideal price, but you need to put in a fixed electricity cost< In the second half of 2017, the virtual currency ushered in a bull market. Before that, whether you buy bitcoin or Ethereum, it's easy to double your assets, but it's a transition to the market in 2018, Most of the quilt cover, and fry money overnight rich have, overnight bankruptcy also have. Similarly, currency speculation can be divided into the following situations:

1. The most common way of currency speculation is to buy at a low price and sell at a high price. It's easy to make money in a bull market. As long as you are optimistic about the currency and find a low price to buy, you can sell by yourself (I suggest that the mainstream currency is better)

2. In private placement, some newly issued but not yet listed coins will be privately raised, that is, crowdfunding. At the beginning, it is a low price, which may be a few cents or even a few cents. In the process of issuing and listing, there are unlimited possibilities. It is very possible to double or even ten times the price, but there are also some cases that can not be launched on the platform or broken, So these are not worth money in hand, just a series of figures. At the same time, private placement is not allowed by the state

3. Contract trading, which is the trading object or subject matter of futures trading, is a standardized contract formulated by the futures exchange to deliver a certain quantity and quality of goods at a specific time and place, and the futures price is achieved through open bidding

generally speaking, contracts can be bought up and bought down. When the market is in a bear market, buying up and currency price rising can bring benefits; Buying down and currency price falling will bring profits. Meanwhile, bear market fluctuation is small, and leverage can be added to increase the amount of capital

therefore, with the development of virtual currency and the recognition of many countries, virtual currency will not only be mentioned in real life, but it is also reliable to invest in virtual currency. However, in different periods, facing different market, there will be different ways of investment. If you choose to hoard money at a high price in a bull market, it is not reliable, So whether you invest in virtual currency depends on how you invest

7. Coin an mining pool not only provides mining services, but also provides position rebate services. It allows miners to automatically switch the hash rate to mine the three most profitable supporting coins based on SHA-256 algorithm - bitcoin (BTC), bitcoin cash (BCH) or bitcoin Sv (BSV). This new function can increase the average income of users using this function by 1%. Help miners make more money.

8. No one can go, of course
if you log in at home, the network will be restricted

the problem is that it is difficult to realize.

9. How to develop a game with cocos2d-x? The result of this problem should be a process. I will explain it from some long-term PC game development experience combined with the functions of cocos2d-x. First, determine the game plan. Determining the plan determines the scale of the game and the required moles.
