the first conclusion: ripple is not a currency, but a payment network; XRP currency used in the network is a kind of currency. Compared with bitcoin, the former is a payment system, while the latter is money, which is not the same kind of things, so there is no substitutability
bitcoin has been fried rotten, and hushang's answer is close to saturation, so we don't need to repeat our work. Let's focus on ripple
what is ripple
ripple is an open payment network. Just like ripple, the word ripple emphasizes the flow and transmission of funds
in life, acquaintances borrow money from each other and may not write IOU. Sometimes, several friends borrow money from each other, generate multi angle debts, and may adjust the relationship of debts and creditor's rights according to the alienation of relatives. For example, a owes B 5 yuan, B owes C 5 yuan, and a and C are familiar with each other. Once three people discuss, they may directly ask a to repay C. In fact, not only between acquaintances, many small shops and small companies will allow acquaintances to write off on credit
that is to say, everyone is more willing to have debt relationship with the people they trust or are familiar with, and through the trust network between people, funds can flow smoothly
the above is the money network between people in the real world. If all this happens in the Internet world, it is the money flow system that ripple is trying to achieve
but in this network, the relationship between you and your trusted acquaintances is transformed into the relationship between you and your trusted gateway. As the name suggests, a gateway is a "gateway" between one network and another, that is, a network gateway. To go from one room to another, you have to go through a door. Similarly, to send information from one network to another, you have to go through a "gateway", which is the gateway. As the interface between network and network, network and the real world, gateway is like a bank counter, which converts your currency into a series of numbers in your account
what happens in ripple is just like the reality. When you change 100 RMB into FCY issued by gateway a through gateway a, you will have an extra amount of 100fcy in your ripple account. You can transfer the 100fcy to a stranger through gateway a, such as Xiao Ming, Xiaoming can exchange the money into real-world RMB through gateway a. In the whole process, the relationship between creditor's rights and debt changes as follows:
1. You deposit 100 RMB into gateway a, and gateway a owes you 100 RMB and gives you a 100fcy IOU
2. You pass the IOU of 100fcy to Xiaoming through gateway A. at this time, gateway a no longer owes you money, but owes Xiaoming RMB 100, because the IOU is in Xiaoming's hands
3. Xiao Ming takes the IOU to go to gateway a to cash RMB 100
in the whole process, you and Xiao Ming only establish a trust relationship with gateway a, but you and Xiao Ming do not need to establish a trust relationship
what is XRP coin
what is XRP coin at the beginning? Its main function is to pay transaction costs
XRP is a kind of cryptocurrency embedded in ripple system. Unlike bitcoin, ripple issued 100 billion XRP coins at the beginning of its establishment, and the total amount is no longer increasing, that is to say, it has g up the mine ahead of time. Each transaction (for example, you transfer 100fcy to Xiaoming) requires a small amount of XRP currency, which is technically destroyed directly. At the same time, XRP coins are also used as margin. When you open a ripple account, you need to put 50 XRP coins in it as a guarantee
according to opencoin, the issuing and maintenance company of ripple, the first 100 billion XRP coins will be given to investors and founders, 50 billion will be distributed free of charge (that is, opening accounts for free for a period of time), and the other 30 billion will be held by opencoin, which will be sold from time to time to make profits. Opencoin also admits that holding and selling XRP coins is the only way to make a profit<
ripple's influence
at the beginning of ripple's birth, rumors abound. Many people claim that ripple is more in line with the operation mode of money flow in reality, and will replace bitcoin in the future
but in fact, it is too early to judge whether ripple system can succeed. As soon as ripple started to operate, many problems have been exposed, including that its security is not as good as the official propaganda
at the beginning, ripple itself is just a new currency circulation system or payment network, and the essence of XRP currency is the lubricant to assist the currency circulation in the system. If this system is successful one day, it will only have a positive impact on the circulation of bitcoin. To say that "Ripple can replace bitcoin" is actually equivalent to saying that "Alipay can replace the renminbi" is wrong: the former is the payment system, the latter is the currency, not the same thing, so there is no replaceability. The emergence of Alipay has facilitated the payment and flow of RMB. Similarly, if the Ripple system is successful, its role is only to facilitate the payment and circulation of legal tender and bitcoin.

@ Feng Chiyu
only mentioned the scene of ripple when users and users pay, but ripple is far more than that. I add two points: trading system and automatic path search
through a gateway, you can deposit RMB, US dollars or virtual currencies, such as bitcoin and Leyte currency, into ripple wallet. And in this system, you can achieve any currency to buy or sell a single transaction. Trading here is better than trading platform. The transaction information of traditional trading platform is not open and opaque. In ripple, every order, cancellation and transaction record can be fully inquired. Through websocket interface, developers can also implement automatic trading program, and basically get real-time data in addition to network delay Network delay depends on the situation, the delay of using US server may be less than 0.1 second!) However, most of the traditional trading platforms have a certain cache time for the API interface. A few seconds of cache time may be fatal to the automatic trading program
with this trading market, ripple can realize a very advanced means of payment - automatic path search
to give a practical example, if I was a Chinese programmer working for a company in the United States, I might get us dollars through Western Union remittance or other ways before, and then I would go to the bank to exchange them for RMB. In the middle of this, the handling cost is relatively high. With ripple, I can do this now:
I trust a RMB gateway, such as ripplecn or ripplechina gateway, which is one of the best RMB gateways in China. Then American companies deposit bitcoin or US dollars through bitsmap gateway and send them to ripple. The service charge is only about 0.000012xrp, It is equivalent to about RMB 0.00000108. Then I will directly receive the CNY quota in the ripple system and withdraw it at the RMB gateway. The service charge for withdrawal is 3% for ripple CN gateway and 6% for ripple China gateway. It only takes a few seconds to complete the automatic exchange payment in ripple system
the full-automatic exchange in the payment step is the automatic path search of ripple, which is the essence of ripple system. Path automatic search relies on the above-mentioned hanging single transaction system. If the above American company deposits bitcoin, the system will complete the following calculation in a few seconds: query the amount of XRP after BTC / XRP exchange, and then the amount of CNY after XRP / CNY exchange. If there is a more appropriate path, such as BTC / USD - & gt; USD/XRP-> XRP / CNY, or BTC / USD - & gt; USD / CNY, the system will also automatically calculate and find the cheapest path for the sender to complete the exchange payment
once, I used ripplecn gateway CNY, and my friend only trusted ripplechina. He wanted me to give him 10 yuan, so I entered the sending interface to input 10 yuan, but the system showed that I only needed to send 9.9998 yuan. Because there is a price difference between the two gateways in the CNY / XRP trading market, the system automatically realizes the path search and provides me with the cheapest payment path
there will be many applications on ripple in the future, and ripple's second payment experience is excellent. If you have a ripple wallet, try clicking send in the wallet and the recipient enters it [email protected] perhaps [email protected] There will be a call fee and Q coin recharge interface, which is an application I made for ripple. You can use XRP, U.S. dollar, RMB, bitcoin and other currencies to purchase q-coin, and exchange it into RMB in seconds to complete the recharge request automatically
ripple is likely to go against the weather in the future. As for bitcoin? His role in the virtual currency instry is similar to that of legal currency, which is totally different from ripple's payment system<

1 person agreed with the answer
ripple basic concept and principle, others have answered, simply speaking, it is a payment network, anyone can become a node of this network to issue currency and then circulate throughout the network. There are some innovations
but in the long run, it must grow faster than bitcoin, otherwise it is likely to lose in the competition, because at present, most of its functions can be realized in bitcoin network
from a technical point of view, because bitcoin has "dyeing" technology, anyone can issue currency, stocks, funds and so on by becoming a node on the bitcoin network. Assuming that the bitcoin is fully legalized, Alipay will turn 1 bitcoin "dyed" into the one and only special bitcoin that is unique and unforgery in the bitcoin network. Then it will promise the public that the stained coin can be exchanged for Alipay by 1 yuan. So the public can use Renminbi to exchange Alipay's "bit yuan" for consumption and payment. So these special bitcoins have what experts call "guarantee" or "anchor". As long as Alipay is credible, these "bit yuan" will always be valuable and can be used safely. At the same time, as bitcoin transactions are open throughout the network, everyone can see how much Alipay has issued "bit yuan", whether it has spammed money and oversold its own assets to guarantee the currency. So the only advantage of ripple in technology is that it can transfer money quickly. It doesn't need bitcoin to wait for dozens of minutes. But in the long run, bitcoin can speed up the transfer speed to a few minutes in the future through technical upgrading
bitcoin network has been able to process a lot more transactions per second than the current processing capacity. But it's not fully mature enough to scale up to major credit card networks. The work to raise the current ceiling is in progress, and the future needs are very clear. From the beginning, every aspect of the bitcoin network has been maturing, optimizing and specialization, and this process will continue in the next few years. With the increase of traffic, more bitcoin users may use lightweight clients, while full network nodes may become more specialized services. For more details, check out wiki page extensibility.
but you can sell it. If you can't find someone to ask for it, go to those QB stores and offer it at a low price.
otherwise, it's troublesome for you to sell something on the Internet.
if you have more, you can open a shop on the Internet. After all, it has no reputation. If your price is not very low, few people will buy it.
then you can try your luck through the intermediary websites in various places, There are all kinds of things sold above. They are all local transactions. It's safer
there are also websites that buy and sell game equipment,
but the ones on the Internet are not very reliable
that's all I can say. Please refer to it yourself.
the e-go card of Shanghai Pudong Development Co., Ltd. is actually any master card. You can apply for virtual cards of UnionPay, visa, MasterCard, express and four card organizations
specifically, the virtual card of express has the following advantages:
1
at present, there are only three domestic express cards that can be free of currency conversion fee, including BOC private bank, all the Express cards of Shanghai Pudong Development Bank, and Minsheng international student express Xiao. In terms of exchange rate, BOC is the best, followed by Minsheng and Shanghai Pudong Development Bank. In addition, other express cards generally charge more than 1.5% of the currency conversion fee
2. RMB bookkeeping
this should be the advantage of Shanghai Pudong Development Corporation over people's livelihood. Some people think that the U.S. dollar is good for accounting, and they say that they can choose an appropriate exchange rate to purchase foreign exchange. However, if you have experienced the design of the central government's interest rate cut leading to a sharp drop in the RMB exchange rate and the people's livelihood's initiative to exchange foreign exchange, you will know how intimate it is to lock the RMB exchange rate in bookkeeping
3. The security is relatively good
because the virtual card of Shanghai Pudong Development Bank's express is a virtual card, it can not be made into a physical card to be swiped on overseas POS. In addition, Shanghai Pudong Development Co., Ltd. has developed a one-time security code mechanism. Although it can't prevent Amazon, a website that ignores security, it is relatively better than those cards whose security codes are printed on the front
by the way, the disadvantages
1. The exchange rate of Shanghai Pudong Development Co., Ltd. is not very good. According to the measured results, the exchange rate of Shanghai Pudong Development Co., Ltd. is relatively poor, about the same order of magnitude as that of China Merchants Bank. Therefore, if BOC can issue platinum version of express card, BOC will be preferred
2. Too little hair
there is no discount for chicken manure. The rebate is also small
3. The quota is too low and there are too many harassment
in a word, this virtual card is very suitable for Haitao group.
simply speaking, Pudong Development's ego card is just a virtual payment channel. With this card, you can associate any physical card of Pudong development, and use the physical card as the main card to apply for the virtual cards of UnionPay, visa, MasterCard and express. The virtual card can only be used for online payment and share the amount with the physical card. I don't know. Do you understand
If hi Tao, this card is very easy to use. It is of little use in China
I recommend you to make the virtual card of express, which has several advantages:
1. At present, the free currency conversion fee of express card is the private bank of Bank of China, Minsheng's Xiao and Shanghai Pudong Development Bank. Other banks are basically 1.5%
2. Shanghai Pudong Development Co., Ltd. keeps accounts in RMB and locks in the exchange rate< 3. Ego has a one-time security code
4. Virtual cards can not be made into physical cards for overseas consumption to ensure the safety of funds
hope to solve your question
good luck.
In short, Pudong Development's ego card is just a virtual payment channel. With this card, you can associate any of your Pudong Development's physical cards. At the same time, you can use the physical card as the main card to apply for the virtual cards of UnionPay, visa, MasterCard and express. The virtual card can only be used for network payment and share the amount with the physical card
1. At present, the free currency conversion fees of express card are BOC private bank, Minsheng Xiao and Shanghai Pudong Development Bank. Other banks are basically 1.5%
2. Shanghai Pudong Development Co., Ltd. keeps accounts in RMB and locks in the exchange rate 3. Ego has a one-time security code4. Virtual card can not be made into physical card for overseas consumption to ensure the safety of funds
In order to prevent illegal cash out. The credit currency of Agricultural Bank of China cannot be transferred to the debit card bound to the third-party deposit, so it is necessary to terminate the contract of the third-party deposit, or change a card bound by Agricultural Bank of China and then transfer it out
a credit card can only be transferred to the savings card of the cardholder's peers, and the transfer to the savings card of the cardholder's peers is regarded as cash withdrawal, and cash handling charges and interest are charged
a debit card is a bank card issued by the issuing bank to the cardholder, which has no credit limit and is used by the cardholder after deposit. Debit cards are divided into transfer cards, special cards and stored value cards according to their functions. A debit card cannot be overdrawn. Transfer card has the functions of transfer, cash deposit and consumption
