litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization
3, infinite coin
infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment
one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical
infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour
Quark coin is not the currency in real life, it exists safely in the computer of global networkquark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective
only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized
quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two
Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost The total number ofzetacoin is 160 million, 1000 zets per block and half of 80640 zets per block
at the end of October 2013, Hong Kong GBL platform absconded with money, and the whereabouts of more than 20 million RMB were unknown

the virtual bitcoin mine developed by Zhongben Cong can proce 21 million, which will be completed in 2140. From the first batch of 50 after 2009 to now, more than 13 million have been excavated, and there are still 8 million in the remaining 100 years. It sounds like the method of locking in the total quantity is used to increase the price. Does anyone think that since it is a virtual mine, someone will design a second or countless similar mines in the future. Moreover, with the development of the Internet, the proction process of the virtual currency designed later is more complex and interesting than bitcoin
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world

when bitcoin appears, it has already played a role in disrupting international finance. Countries must not watch virtual currency signal to disrupt their own financial markets. As a result, the major league of international financial organizations must crack down on or force the rectification of the virtual goods market, just like international terrorists
in addition, virtual currency has no ability to resist risks at all, and does not have the standard of credit rating at all. At that time, thousands of virtual currencies will return to the starting point of game currency
after a period of false speculation, the indivials or organizations of Zuozhuang have quietly left one after another, and the remaining virtual currency owners will face the end of "poor people kill evil people". Even if they fight hard, it will not help, and the result must be very miserable.
