bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

International credit card (foreign currency card): at present, there are six major credit card organizations in the world, MasterCard and JCB of MasterCard, visa and American Express (Visa International) of American Express and Diners Club of UnionPay. The cooperative banks are: Instrial and Commercial Bank of China, Bank of China, construction bank, agricultural bank, China Merchants Bank, instrial bank, HSBC, Standard Chartered Bank and Bank of East Asia. The common foreign currency of international credit card is US dollar set. There are MasterCard and JCB of MasterCard, visa and American Express of American set. Most of the foreign currency of credit card is converted in US dollar, but the bank will convert from Euro or pound sterling into US dollar at the time of settlement, which may cause a little cost e to the exchange rate difference. In addition, many banks also offer special currency or multi currency credit cards. Such as RMB Euro credit card, or multi currency credit card. The foreign currency of this kind of credit card is directly settled into RMB, which saves the exchange rate cost caused by intermediate conversion. Dual currency card refers to the credit card with both RMB account and foreign currency account. Generally, the top right side of the card is pasted with the "UnionPay" logo, and the bottom right side is pasted with the logo of visa, JCB or Mastercard. At present, visa or Mastercard al currency credit card can be used in more than 200 countries. When the al currency credit card is used for domestic consumption, it adopts RMB settlement. When the card is used abroad, it will automatically enter the foreign currency settlement system. According to the different types of cards, it will be converted into US dollars or Euro first, and then converted into local currency for settlement when the card is used in non US dollars or euro, When repaying the loan, we need to convert it again. Because of the currency conversion, we have to charge 1% to 2%. When returning for repayment, you need to exchange money first, and then there will be a currency conversion fee. The main function of full currency is to avoid currency conversion fee and to handle the transaction demand of all currencies. No matter where you spend, you can repay in RMB directly after you return home. In addition, the bank's all currency international card usually gives you a high amount of travel accident insurance.

multi currency card not only integrates the advantages of single currency card and al currency card, but also avoids their disadvantages. Moreover, the multi currency cards issued by all banks are free of annual fee. The only drawback is that all currency cards do not support UnionPay channel for the time being. At present, the banks that the international credit card organization cooperates with China are: Bank of China, instrial and Commercial Bank of China, Agricultural Bank of China, Construction Bank of China, Bank of communications, China Merchants Bank and Everbright. The card issued by the member (bank) of international card issuing organization can be signed by the special agent of the organization. This kind of card is called international card. As we all know, visa, master and JCB are the three major international organizations. Visa has the highest market share, followed by master and JCB, but JCB is easy to use in Japan, not necessarily in other places. Although JCB is also an international card, some online shopping does not accept JCB. Usually, international credit cards use US dollars as the settlement currency, and international credit cards can be used for overdraft consumption (consumption before repayment). The most common credit card brands in the world are visa, master card, etc., and major domestic commercial banks also have international credit card business, You can easily apply for credit card at the bank counter. It should be noted that there is no interest on deposit in international credit card. International credit card foreign currency card foreign credit card Hong Kong card visa Taiwan credit card MasterCard American Express foreign credit card please go to Shenzhen Huaqiang Beiyi credit card set. The US dollar (US dollar) or Hong Kong dollar (Hong Kong dollar) and euro of ICBC's al currency credit card can only be swiped at the overseas POS machine. Some people also take the overseas POS machine to China for use, Moreover, it needs visa, MasterCard or American Express system to be installed, but UnionPay system cannot be installed; Domestic pure foreign currency cards (International cards, no UnionPay logo) and all foreign cards, including Hong Kong credit cards, also need to be swiped in the POS machine equipped with this system. However, as long as the POS machine is issued in China, there is no need for an overseas machine. That is to say, the special card should be swiped in the special POS machine. It's like the installment card of home decoration of China Construction Bank; Instrial and Commercial Bank of China Peony special installment card (installment direct home decoration card); ICBC Yidai credit card, ICBC Yidai debit card, ICBC Yidai savings card; Bank of communications easy to enjoy the loan, these credit cards can only be swiped in the bank's special merchants.

editor of the three major international credit card organizations
visa is a global payment technology company, connecting consumers, enterprises, financial institutions and governments in more than 200 countries and regions around the world, promoting people to use digital currency more conveniently instead of cash or checks. Visa owns and manages the visa brand and all payment procts based on the visa brand - Visa brand cards
at the same time, as the credit card with the highest market share in the world, visa card can be accepted at more than 29 million merchant transaction points all over the world, and can provide cash withdrawal service at 1.8 million ATMs with unlimited convenience. There are more than 1.85 billion visa cards in circulation worldwide, which proves that visa is the most popular payment brand. Visa offers a wide range of credit and debit procts to meet all kinds of payment and living needs
Master Card: Master card MasterCard is an international organization, whose basic goal is to communicate the bank card information exchange between domestic and foreign members, and to facilitate issuers to enter the bank card and traveler's check market and seek development regardless of their size
MasterCard is a household name all over the world. However, thirty years ago, it was only a domestic card in the United States. Its popularity lies in the fact that MasterCard International organizations have been providing cardholders with the latest and most complete payment services in line with the belief of serving cardholders, so it is recognized by cardholders all over the world. How to choose a credit card when traveling abroad can make overseas consumption more cost-effective, which is really a bit particular. Credit card experts said that the choice of which bank's credit card is not very different, the most important thing is to distinguish between al currency card and foreign currency card. Double currency card and UnionPay card can save money by PK: when the cardholder uses the double currency credit card abroad for consumption, he has to pay 1% - 2% of the total transaction amount as a one-time currency conversion fee, and at the same time, he has to bear the exchange rate risk. At present, most of the al currency credit cards provided in China are settled in RMB and US dollar. If the cardholder can't settle in US dollar or RMB in the place where he travels, and uses al currency credit cards overseas, he needs to convert the local currency into US dollar for settlement. After returning to China, when repaying in RMB, we have to convert US dollars into RMB. In this way, there may be two times of exchange rate conversion, there is a certain risk of exchange rate fluctuations, which may bring some exchange rate losses to cardholders. Experts suggest that in overseas areas that have opened RMB card business, it is best to choose UnionPay card. Because, through the UnionPay channel, the consumption amount will be directly converted into RMB according to the exchange rate, so there will be no exchange fees. This process only involves one exchange rate exchange process, paying the least RMB. UnionPay card has only one exchange rate exchange, which can relatively rece the exchange rate loss of cardholders. Shenzhen credit card consumption in US dollars, card consumption, East Asia credit card consumption, Shenzhen traffic easy to enjoy loan consumption, Shenzhen ICBC Yidai credit card consumption, Shenzhen ICBC Yidai credit card consumption, Shenzhen foreign currency card consumption, international card consumption, Hong Kong credit card consumption, credit card consumption in US dollars, Hong Kong dollar card consumption, Hong Kong dollar card consumption, foreign currency card consumption, International foreign currency card MasterCard; Visa visa; American Express and JCB card in US dollar or Hong Kong dollar, euro, Japanese yen, Australian dollar, Korean won, Swiss franc, new Taiwan dollar and so on. However, overseas, visa and master have more outlets and are more convenient to use than UnionPay. Choose the right foreign currency card to rece exchange rate loss: UnionPay network has not been fully spread, in some countries and regions, not every merchant can use UnionPay card. At this point, it's necessary to have a visa, MasterCard or JCB card in hand. In order to avoid the currency conversion fee generated by overseas credit card, we need to choose the appropriate foreign currency credit card before traveling abroad. Credit card experts suggest that when a cardholder swipes a credit card abroad, it is best to choose a foreign currency card with the same local currency as far as possible. If you want to travel to Europe, you'd better choose Euro card, Japanese yen card and Hong Kong dollar card. Foreign currency cards are classified according to currency. The most common ones in China are US dollar card, Hong Kong dollar card, Euro card and Japanese yen card. Choosing the right foreign currency card can rece the loss of exchange rate. In countries and regions where the common currency is not US dollar, such as Europe, when using the card for consumption, the recording currency is the local currency. Few banks have issued all currency cards. I don't know whether you want to ask about all currency or multi currency cards. China Merchants Bank has issued all currency cards without annual fee. The cards only support visa lines, which are applicable to foreign countries. As long as visa lines can be used, they are free of exchange fees. Usually, if the al currency card, such as MasterCard, non US dollar card will charge a handling fee, according to 1% exchange to the US dollar account, of course, you can still return RMB
the UnionPay line, that is, UnionPay POS, can be used to swipe the card.

5. In the old world, you can go to two places: one is the spider hole in the wetland, the other is the blood mine hole in the alaxi highland. After 200, you can go to the barren land. After 250, you can go to the burning plains. After 290, you can go directly to Mars. After 360, you can go to Northrend
6. After coming out of the novice village, there are many places to earn gold coins in Biqi city. When the level reaches level 15, you can go to the novice receptionist to choose "I want to practice" and enter the first map skull Valley (level 15-22). After mages, Taoists and soldiers have learned the skills of level 17 lightning, level 18 soul fire and level 19 attack and kill swordsmanship, they will be much easier to fight in the valley. Skeleton Valley is divided into three layers. Don't underestimate skeletons and zombies. In the third layer, the rare skeleton spirit and corpse King refresh faster than the map outside. The refresh speed is very fast. It will refresh in about 15 minutes, and the explosive things are quite considerable. There are all kinds of weapons, headgear, potions, skill books, and when you learn thunder and lightning, soul fire and vice versa After attacking and killing swordsmanship, fighting is more relaxed and pleasant. But be sure to set up a good health protection, electric zombies are not joking
after level 20, players can choose to do mainline tasks or continue treasure hunting. If it's a treasure hunting in the new area, the first choice is the hall of overlord in FengMo valley. However, there are limitations. The mage can go at level 17. The Taoist needs to finish practicing skeletons, while the warrior needs to be able to assassinate level 25. However, it's no problem to form a team. The boss little white pig in the hall of overlord is very friendly and polite to our players, Every time you have a baby, you will give it away. If you have time to play treasure first, you must go to see friendly Xiao first. Moreover, the environment of the bully hall is very suitable for you to play treasure and save money, because the store NPC and warehouse NPC are in it, which is convenient for you to access and buy and sell things. Therefore, you must go to the bully hall to see friendly Xiao when the level is not high. In addition, players who don't like adventure can go to the caves and orc tombs above beech city. After entering, don't beat all kinds of monsters. Just find a single bat. A single bat is easy to explode money and roll back to the city. With good luck, the roll back to the city and gold coins burst out one after another are enough for you. Each bat can explode up to 3000 gold coins, and the roll back to the city can be tied up in the warehouse, If you want to sell more than 6000 gold coins, it's equivalent to a bat's net profit of about 10000 gold coins. This business can be done. In addition, the Biqi mining area also makes a lot of money, especially the black iron ore, but it is relatively slow compared with other treasure hunting maps
after level 30, there are more places for mages to go. They can go to the evil valley of Biqi novice receptionist, or to the niu7 niumo Hall of niumo temple on cangyue island. It is recommended that mages go to niu7, because mages who have learned hell thunder light form teams in it. They only need MP blue, but HP red can't be used. Moreover, the drugs released by niumo general and niumo sacrifice are quite sufficient, The equipment also exploded a lot. In Niu 7's world, it can be said that in the world of mages, when the backpack is full, go back and change it into gold coins immediately, and then go again. Calculate the time each time, even if it's slow, a 30 minute trip. After the backpack's equipment and medicine are sold, it should be no problem to get 10W gold coins. As for Taoists and samurai, they can form teams to go to the evil valley. The third layer can also brush white and evil snakes. It's quite easy to fight. There are a lot of things that explode. They are all 8x8 or 16x16. It's easy to sell more than 10 W with a full backpack. Compared with the mage, although it's not easy to fight, the effect is the same. They can sell things back to the city in 30 minutes to make money
after level 40, there are more places to make money. You can team up with friends to go underground to make treasure. You can also choose Zuma temple and magic dragon city. Zuma temple is the best place for a single player. Each room of Zuma Pavilion is painted with only one monster, and they are all top-notch monsters. The explosion rate is quite high. Zuma temple is rich in weapons and jewelry, Moreover, the burst rate of weapons is the highest, and it's much easier for a single player to go to each room to fight. It's the preferred place for level 40 players to fight treasure and earn gold coins.
