How to invade bitcoin exchange

1. When a user makes a transaction, he can only trade the currency in each transaction account. If he needs to trade the currency in his wallet, he needs to transfer the currency fund in his wallet to the corresponding transaction account, and then he can carry out various transactions. Of course, first of all, you need to have an okex account, and then you can trade bitcoin in legal currency, currency or contract.

2. There are two main trading methods: one is exchange trading, which is very safe in well-known large-scale exchanges, and the other is OTC trading. Many platforms provide guaranteed transactions similar to Taobao, which are also relatively safe
the key is to go to the mainstream platform

3.

at present, the vast majority of digital currency transactions are concted in exchanges. Among the numerous exchanges, bitfinex, binance, okex and so on are well-known

However, bitcoin and other digital currencies, as decentralized assets, have to be traded in a centralized exchange, which seems to have hidden contradictions and dangers

1. Problems and challenges of stock exchanges=“ https://iknow-pic.cdn.bcebos.com/fd039245d688d43fdf16c83b761ed21b0ff43bbf ">

in February 2014, Mt. GOx, the world's largest bitcoin exchange at that time, was stolen 850000 bitcoins, and the price of bitcoin suffered a" cliff "crash on that day. Later, it was revealed that Mt. GOx was in fact a thief, and only 7000 bitcoins were actually stolen

in August 2016, bitfinex, the largest U.S. dollar bitcoin trading platform, suffered a security vulnerability, resulting in the theft of 120000 bitcoins, which was worth $65 million at that time. If converted into the price in December 2017, it would be worth nearly $2 billion

on December 19, 2017, South Korea's youbit exchange was attacked by hackers and lost 4000 bitcoins, and the exchange declared bankruptcy

on December 21, 2017, the Ukrainian liqui exchange was stolen 60000 bitcoins, and the unit price of bitcoin plummeted by US $2000

in 2018, such a drama will only continue

in addition to the threat of hackers, traditional exchanges also have some inherent shortcomings, such as lack of supervision and inefficiency. The security of the exchange for investors can only rely on its own credit, and the cost of running is very low. The stock exchange is regulated at the national level, but there is no such sword of Damocles on the top of the digital currency exchange. Moreover, in an exchange, the same order can only be submitted to one exchange. After the user places an order, the funds used for the transaction will be frozen and can only wait for the completion or cancellation of the transaction. These are undoubtedly inefficient

All in all, the problems of exchanges are the problems of centralization

2. Decentralization of exchanges=“ https://iknow-pic.cdn.bcebos.com/86d6277f9e2f070889a173c9e224b899a801f257 ">

(1) the progress of the exchange itself

the upgrade of security means is various. At present, the best use is cold wallet, that is, to keep the digital currency in the offline U disk. At the end of 2017, when the YouTube exchange was attacked, 75% of its assets were withdrawn into the cold purse in time to avoid greater losses. However, it seems to be a helpless way to protect the online assets by offline means. Of course, there should be many other methods, which will not be repeated here

(2) the representative of cross ledger transaction is ripple network, and the operating company is ripple labs, which is a semi centralized system. Ripple is a decentralized clearing agreement. In order to solve the high cost and delay of inter-bank clearing, its base currency is XRP. Ripple network can connect all kinds of assets, such as US dollar, RMB, Japanese yen, bitcoin, etc. to its own network. In this system, U.S. dollars or bitcoin can be converted into reborn currency, and then reborn currency can circulate freely in the network, just as a highway is built between various assets. Due to the support of major banking institutions, the reborn currency achieved nearly 300 times growth in 2017

(3) decentralized exchange

some teams try to use blockchain technology to build a decentralized exchange. This kind of decentralized exchange, to some extent, is an extension of cross ledger trading

bitshares is the most representative of early rising projects. It builds a blockchain development platform with servers scattered all over the world. Even if some of them are attacked, the system will not collapse. Anyone can transfer money and borrow money freely on this platform, and can also quickly build a centralized exchange based on this platform. In order to ensure stable value, bitstocks also require three times of digital assets as collateral. At present, bitstocks are running fairly well

later, with the development of Ethereum and smart contract, the x x protocol came into being. This is an open protocol running in the Ethereum blockchain and a decentralized exchange in the Ethereum ecosystem. The agreement has attracted many investors. At present, it has completed financing and started to build open source software tools and infrastructure. Of course, there are many competitors. Ether Delta, IDEX and oasis DEX are trying to provide similar functions. Moreover, it is a smart contract system based on Ethereum, which only supports erc20 token. If other smart contract public chains start to rise, the demand will be reced

in addition, there are some teams that are entering, such as the domestic road seal agreement, looping (LRC) in English. They adopted a design similar to the X protocol, and also introced a fast payment function similar to the lightning network. It is characterized by trying to match multiple exchanges, the user's order can be broadcast to multiple exchanges, and completed by different exchanges. Moreover, the user can still use the account funds after placing an order, and the user's behavior of transferring part or all of the funds is equivalent to partial or total cancellation. To some extent, it improves the breadth and timeliness of the transaction. However, this system seems to have damaged the "power" of the existing exchanges. Whether we can persuade everyone to play together will be a difficult problem

At present, there is still a long way to go for the construction of decentralized exchange. In 3-5 years, traditional exchange will still be the main battlefield of digital currency

However, in the future, it is worth looking forward to let the decentralized digital currency get rid of the shackles of centralization

4. 100m bandwidth has little to do with the connected computer
because the connected computers are controlled by the policy settings of the router
the most important thing is to allocate your bandwidth reasonably. In theory, if you download resources from a computer in your network segment, if your router does not allocate bandwidth, it may cause the computers in the whole network segment to get stuck on the Internet
if the distribution is reasonable and the router is powerful, then 200 computers can be easily handled.

5. It may also be because it can't stop the development trend and it needs to be decentralized

6.

As far as I know, there are probably two ways to obtain bitcoin. One is to use assets such as cash to trade with other bitcoin users. Generally speaking, the value of assets is determined according to the market value of bitcoin. However, the market value of bitcoin fluctuates a lot, and there may be hackers on the trading platform, so there may be some risks in this way

So if you want to get bitcoin by mining, you need a computer with high performance and a lot of manpower to maintain it. All in all, acquiring bitcoin is an investment and needs to be managed reasonably< br />

7. Freundlich adsorption equation can be applied to both monolayer adsorption and heterogeneous surface adsorption. Freundlich adsorption equation, as an empirical adsorption isotherm of heterogeneous surface, can well describe the adsorption mechanism of heterogeneous surface, and is more suitable for low concentration adsorption. It can well explain the experimental results in a wider concentration range. However, the disadvantage of Freundlich adsorption equation is that it can not get a maximum adsorption capacity and estimate the adsorption beyond the concentration range of parameters

8. Buy bitcoin
if you have the experience of buying and selling stocks, it's easier to buy and sell bitcoin. In order to better understand the new people, I will take selling and buying stocks as an example to talk about the trading of bitcoin
if you want to buy stocks, the first thing you need to do is to open an account in the stock exchange company, and then bind the bank card for trading. Nowadays, many young people will choose to open an account online, and then directly buy the stocks they value through the Internet. This approach is closer to bitcoin trading
buy bitcoin by buying stocks: first of all, you need to register your account number (fire coin, cloud coin, etc.) in the relevant bitcoin exchange, and your account number needs to be registered by email. After the account number is registered, enter the exchange to fill in the relevant information and bind the bank card, and then transfer the funds to the exchange through online banking transfer. Finally, you can buy bitcoin
transfer note here needs to be noted: the exchange does not accept Alipay, WeChat and other transfer methods. It's usually through online banking. So we must pay attention to this
after the above operation, you can get the first bitcoin in your life. Since China banned all domestic bitcoin related exchanges in September this year, it has become somewhat difficult for RMB to buy bitcoin
therefore, bitcoin cannot be purchased by the above methods in China
the current method of purchasing bitcoin
e to the prohibition of domestic exchanges, the purchase of RMB becomes more and more difficult. Of course, if you've been trading all your money before, you can just exchange bitcoin directly. If you don't have money on the exchange, you need to buy bitcoin over the counter< Over the counter trading (OTC): you can understand it as a trading mode like Taobao, which is not too much
after the seller registers his commodity (bitcoin) in the corresponding OTC exchange, the buyer who is interested in the commodity will contact. Then the buyer transfers the amount needed to purchase the goods through WeChat or Alipay to the seller. After receiving the money, the seller will transfer the corresponding bitcoin to the buyer. The platform plays a confirmation role in the whole transaction. To some extent, you can understand it as the role of platforms such as Taobao or Jingdong
after you receive bitcoin, you can transfer the bitcoin on the OTC exchange to your previously registered exchange account through the bitcoin address. At present, the commonly used transactions are all coin an, bitfinex, etc. You can also convert your bitcoin into other currencies in these exchanges, such as eth, EOS, BCH, OMG, etc
in this way, the whole process of RMB purchasing bitcoin is successfully completed.

9. Students' salaries are generally not high. About 3000. It's 4000-5000 after becoming a regular. It's estimated that it will be higher after two years....
