1. Investment should be cautious, please study carefully before deciding
virtual currency is a currency that can buy goods and services in a specific community in a virtual space. It has the monetary function of medium of exchange and unit of account
virtual currency can be roughly divided into three categories
the first category
has nothing to do with real currency, and can only be used in a closed virtual environment, usually online games, such as world of Warcraft
the second type of one-way exchange can only be used in a virtual environment, and sometimes physical goods and services can be purchased, such as frequent flyer award program, microsoft points, Nintendo points, Facebook credits and Amazon coin
the third type of two-way exchange, which has a buying price and a selling price, is the same as "real" currency, including those issued by issuers, such as second life Linden coin, two-way exchangeable game currency, etc., as well as decentralized cryptocurrencies, such as bitcoin, Leyte coin, Ethereum, etc; Virtual currency & quot; But cryptocurrency is only one of the subcategories of virtual currency.

2. In addition to bitcoin, there are many other virtual currencies in the virtual world< Liteoin (LTC) was released on October 7, 2011, and is currently the most valuable counterfeit currency, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million
this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)
compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being
the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners
ppcoin
ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age
ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million
ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity
ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<
ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency
terracoin
terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years
however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency
namecoin
namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011
namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time
this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name
in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.

3. It's impossible. It's impossible. If I don't do it well, let others take it
4. Now the mainstream digital currency trading platforms are mainly coin security, fire coin and OK. The choice of trading platform mainly depends on the scale and security of the platform, so as to prevent the platform from running away or being attacked and stolen by hackers
5. Objectively speaking, I think it's better than t-coin, because the interstellar space filecoin is distributed storage, which is very compliant, and now it's also a very popular mining project.
6. IPF is closely symbiotic with filecoin
IPFs is used to locate and transmit data and exists as infrastructure; Filecoin is the economic incentive system of IPFs
without filecoin, IPFs is difficult to start and work; The continuous development of IPFs provides an important basic support for filecoin, and the popularity of IPFs will affect the market's demand for more secure and efficient distributed storage filecoin
mining machine is the machine that you get filecoin, IPFs is a technology, and what we call mining is actually the incentive layer of this technology, which is filecoin.

7. The only similarity between the two should be that they are both virtual coins. The difference is that in terms of generation mode and energy consumption, filecoin does not need large-scale operation and consumes less energy, while bitcoin needs large-scale machine operation and consumes huge energy.
8. Because the value of IPFs has now been reflected, more and more Internet enterprises and blockchain enterprises are going to use IPFs for storage and development, so these companies are bound to buy a large number of filecoin to pay for miners, and the currency price will rise accordingly, which is valuable!
