The ninth wave of fortune finds digital currency
first line: mining, mining machine, mine (ore pool)
all three are related to mining, but they are also different
Mining: we don't discuss the technical details here. From the perspective of profit, mining has the lowest threshold. Even if we need professional mining machinery now, we can still buy a mining machine to make money. If we become bigger, we can open a mine. Without talking about the risk, mining is the simplest way to make money. The investment cost is low, the rate of return is high, and the time cost is high
mining machinery: the business of manufacturing mining machinery is very hot, and there is a high threshold, so it is difficult for non professionals to become manufacturers. Ant mining machine in the bull market does not worry about selling. Especially after 1994, as far as I know, foreign domestic ore feeders were towed away by trucks. However, the threshold of manufacturers is already very high, and it is difficult for ordinary people to get in touch with them, so there are two dealers. Mining business contact is not much, the second-hand market seems to be very chaotic
mines (ore pools) of course, mines and ore pools are inseparable. Why? The mine pool exists in order to avoid the risk of the mine. The mine pool will pay the cost of the miners according to the time according to the calculation force. Of course, it also needs to draw a percentage, and the miners will be able to keep their income from drought and flood. But the only thing to do is to bring people to the mine. Offline mines are also managed by their own machines, and can also be managed by others. There is a certain threshold, risk and income coexist
second line: information platform, exchange, wallet, currency speculation
consulting platform: something that must exist in the Internet era, providing information and consulting aggregation. The first thing new people come into contact with is information media. In the 17 years since the outbreak of digital currency, bitcoin's Internet search index has exploded. Many people want to know about digital currency, so such an information platform is sure to survive. Drainage, content, value realization and value extension are generally the ways of making profits
exchange: the best understanding is that all flows and proction currencies are for trading. Only when a transaction has a price can it be valued. Many problems will also be found in the transaction, such as the famous "bitcoin expansion". Only by finding and solving problems can the instry develop better. We all know the mode of making money in the exchange. It's the makers who make money. It's just like casinos and securities dealers. They lose more money and earn less, but the exchange is stable. In addition to the handling charges, it seems that the money charge is also a profit model. The threshold of the exchange is also high. In addition to trading risk and platform risk, it pays more attention to policy dynamics. Big exchanges now have "currency exchange", "fire currency" and so on
wallets: both hot and cold wallets are procts, and coin circles are just needed for this kind of procts. Online wallet is generally free, and then through other ways to make money, such as usually do exchanges, or there are investment activities
currency speculation: simple speculation, uncontrollable risk, too many factors affecting the price. We can envy the good luck of others, but we should not hope that we have such good luck. Therefore, there are generally three modes of currency speculation, which can be more "smart" to avoid risks: 1. Fixed investment 2. Quantitative trading 3. Arbitrage: spot move brick, futures arbitrage. Now, it seems that there is a fourth kind of profit margin in the OTC channel.
Radar money is a kind of money used in pyramid selling. If the investment should be unreliable, you can also consult relevant professionals
in essence, bitcoin is a virtual currency with limited supply of blockchain technology. Reborn and many other currencies are counterfeit bitcoin. They also use blockchain and limited supply. However, because they are not original, the mass base is weak, and the total amount is more than bitcoin, the speculation price can not catch up with bitcoin. However, several hundred kinds of virtual coins, such as v-treasure coin, later radar coin and so on, are falsely advertised as limited in total amount. In fact, they are digital coins with unlimited supply. In essence, they are a kind of game currency technology plus pyramid marketing propaganda
Due to the continuous popularity of bitcoin, people begin to pay close attention to this kind of digital currency. However, people from all walks of life pay more attention to the technical architecture behind bitcoin - blockchain technology, which is considered by many organizations to be the core technology most likely to trigger the fifth round of scientific and technological revolution after steam engine, power, information and Internet technology
bitcoin may fall, while the long-term direction of digital currency is bound to rise, and the rise will be particularly fierce. In 2017, the total market value of global digital currency was only US $647 billion, less than 10% of the global physical gold market value, and less than 0.01% of the total national stock value. AAC is launched at the right time. Miners all know that the earlier they enter, the more tokens they can get and the more profits they can earn. The birth of acute angle cloud will bring huge returns to its partners
2017 can be regarded as the first year of blockchain technology, and 2018 is likely to be the explosive year of blockchain technology. The rapid development of the blockchain technology will probably usher in the explosive growth of acute angle cloud, and the acute angle PC released on ces2018 is likely to become another explosive proct of blockchain
1. Security risk of running environment
the core file of encrypted digital currency Wallet - private key / mnemonics is stored on the terminal device, whether it is PC or mobile terminal, if the terminal device appears unsafe phenomenon, There is a very high security risk for the private key / mnemonic
at the beginning of design, a secure digital wallet can avoid the possibility of private key / mnemonics being stolen e to the running environment. The security problems of the running environment on the terminal mainly include virus software, operating system vulnerabilities and hardware vulnerabilities
2. The security risk of network transmission
the security of network transmission is more reflected in the ability to resist man in the middle attack. Man in the middle attack means that the attacker creates independent contact with both ends of the communication and exchanges the data they receive, so that both ends of the communication think that they are talking directly with each other through a private connection, but in fact the whole conversation is completely controlled by the attacker
although most digital wallet applications use the HTTPS protocol to communicate with the server, the man in the middle attack method is to get the content of the HTTPS protocol by installing a digital certificate in the user terminal
a secure digital wallet needs to be able to scan the legality of all the digital certificates in the terminal, check the proxy settings in the network transmission process, and ensure the security of the basic network communication environment
in the development of digital wallet, whether to use two-way verification for communication verification at the network transmission level is also an important criterion to measure the security of a digital wallet application
3. The security risk of file storage mode
for the private key / mnemonics of digital wallet, the storage mode of terminal device also needs to be paid attention to in the security design. The access right of private key / mnemonic file directory, the form of private key / mnemonic file storage and the design of encryption algorithm all need to be strictly designed
when we analyze the security of several mainstream digital wallets, we find that even the well-known digital wallets are random in the storage of private key / mnemonic words. There are both plaintext storage and encrypted storage, but the decryption key is fixed in the code, which can not play any role in security defense
4. The security risk of the application itself
the security risk of the application itself mainly focuses on the security defense of the application installation package itself
whether the application installation package has the ability of anti tampering is a very core technical ability. In addition, memory security, anti debugging ability, life cycle management of private key / mnemonics, security of debugging log and security of development process also need to be enhanced
5. Security risk of data backup
if the mobile application can be backed up, it can use the machine with more powerful computing performance to brutally crack the private key / mnemonics. For example, if android:allowBackup Property is set to allow backup, then the backup mechanism of the system can be used to back up the application data files, and the private key / mnemonics of the encrypted digital currency will be backed up to the external media, which breaks the security boundary design of the operating system from another direction
for the majority of users, the security of digital wallet also means the security of wealth, so we must be careful when choosing digital wallet
I have used several wallets such as coin letter socoin and coinplus
in terms of personal experience, socoin and coinplus are very simple and easy to use. They are not only decentralized multi-functional cross chain digital currency wallets with social functions, but also integrate Multi Chain multi currency wallets, payment and settlement platform, currency trading platform, social groups, information market and other functions, which can meet almost all your needs for digital currency in one stop.
5 holes and + 15ed are possible, but it is not so easy to have them at the same time

Yuanshen is an open world adventure game proced and released by Shanghai MIHA you. The original test will be launched on June 21, 2019, the next test will be launched on March 19, 2020, the departure test will be launched on June 11, 2020, the technical open test of PC version will be launched on September 15, and the public test will be launched on September 28, 2020. In terms of data, in the case of the same official server, the account data exchange among IOS, PC and Android platforms enables players to switch devices under the same account
the game takes place in a fantasy world called "tiwat", where the selected person will be granted the "eye of God" to guide the power of elements. The player will play a mysterious role called "traveler". In the free journey, he will meet his companions with different personalities and unique abilities, and together with them, he will defeat the strong enemy and recover the lost relatives. At the same time, he will graally explore the truth of "original God".
The ore concentration points of Yuanshen are qingyunding, Fenglong ruins and large area in the south of the map, and the specific distribution is as follows:
1. The ore concentration points of qingyunding are as follows:
among them, qingyunding is the area with the most crystal blocks, Fenglong ruins is the second dense area, and then the large area in the south, 95% of the original God's collected crystal minerals are distributed in these three areas
extended data:
precautions for crystal ore collection:
1. Players need to pay attention to the fact that crystal ore is very precious, which also makes it difficult to find
Moreover, the refresh time of crystal ore is relatively long, and it will refresh once every three days3. Players should try their best to search near the geological fault in the map, or near the rock exposed on the surface, so that they can get more chances
