Lightcoin OKC
Here are some personal experiences in the exchange
(1) the coin search website has the advantages of low service charge, quick withdrawal and multiple currencies. It supports a variety of well-known virtual currency transactions and is convenient to purchase usdt. It has app and high security
(2) kucoin overseas version (coin win background) has smooth interface operation, and the speed of coin withdrawal is not bad, but most of them are junk ICO coins, many names have not been heard of, such as app
(3) China bitcoin overseas version EXX (slow coin withdrawal, kengdai) gambling platform, fixed-point blasting futures pop you up, there seems to be a problem with cash withdrawal, no app
(4) fire coin overseas version, Collude with OK, dozens of junk money a week, no bottom line, many small problems. Support C2C transactions, there are app
(5) okcoin overseas version, this does not say, OK life black, although support C2C transactions, but bottomless line shelf circle coins, flicker leeks, C2C transactions can not be withdrawn, embezzle the user's assets after the decimal point of tens of millions, careful into
(6) BTCC overseas version, support us dollar UnionPay direct charge, but the handling charge is high, it is relatively low-key in China, The experience of the transaction interface is very poor
(7) the overseas version of cloud coin has few currencies and many problems, so it's all warriors
(8) currency security is currently the largest exchange in China, with the most complete currency and many activities. It doesn't card you to withdraw and recharge money. Although there are so many junk money in ICO, it doesn't have as many problems as hot money OK platform. It can be said that it is the best exchange in China. It has app, needs to turn Q, and mobile client doesn't need to turn Q
(9) Yuanbao overseas version has Canadian financial license, legal operation, insufficient depth, small amount of currency, small transaction volume and insufficient UI beautification
(10) in the bitage, the overseas version takes a very long time to review, and it takes you a long time to pick up the coin and issue the coin. The miner's fee used to be a little higher, but now it's just a little higher. 0.5% for recharge, 1% for withdrawal, and the highest withdrawal fee in the whole universe. The garbage made by the K-line chart can't hold on to the ICO coin. At present, this platform can't stand the temptation of interests, and the card is only issued half a day, The trading volume is a little less. At present, I have abandoned this platform
(11) the overseas version of China's bitcoin has just been opened for trading, and C2C trading has a unique qash trading area. There are many small problems, so be careful to enter
however, once it reaches the bottom of the market, it will start to warm up. Don't forget, last year was a big bull market after LTC / BTC fell below 1%
will LTC return to zero
I don't think so. I'm not saying that LTC will not fall any more. I'm just saying that if BTC has a bull market in the future, LTC will certainly have a bull market. The essence of LTC's current decline is that the niche coincides with BTC, which has no characteristics and application. The myth that scrypt algorithm can resist mining machine has been shattered
but what about other counterfeit coins
e to the strategy of fast halving, the computing power of dog coin is far from enough to compete with LTC. In theory, other algorithms such as X11 and x13, which are known to be able to resist mining machines, will be cracked sooner or later. In fact, coins such as mark and black, which are characterized by anonymity, are not very competitive. Anonymity is just a small demand, Can you imagine that money will be completely anonymous in the future? Anonymity is always just a small demand
I saw a "dark forest theory of cryptography currency" before, and I really forgot who put forward it in the circle. What I said was that under the premise of mining machinery, the currency of sha256 algorithm is easy to be killed by Avalon, so it doesn't grow very long; Now scrypt algorithm mining machine comes out, who is the master of this algorithm field? It can only be LTC. After a lot of currencies fall to a certain extent, they are in danger without the support of computing power. They speed up the capital flight, then speed up the escape of computing power, and enter the dead cycle. It's very difficult to get out and finally die slowly
dog coin is now in such a cycle. Coupled with the fact that it has been halved too fast, the escape of computing power is more obvious. Without computing power, the pow coin is a joke. The system is weak, and the big money can only go out, but the price has been falling, so can computing power. In addition, dog is just a fad culture, just like Jiangnan style, Who else is singing in the street now? Therefore, the prospect of dog coin is very bad. The dog coin is like this, and other scrypt coins are not worth mentioning. It seems that LTC dominates scrypt algorithm
BTC applications are colorful and LTC applications are scarce, which can't be compared. However, other currencies don't seem to have any applications either. All kinds of second-generation coins are too busy to worry about. Therefore, it's not a problem. When BTC rises sharply, it's expected that LTC will rise more than BTC
of course, I'm not encouraging you to buy the bottom. I haven't entered the LTC since 60

By using secure encryption technology to store digital currency, you only need to have a contract address to transfer the currency. The function of this wallet allows you to put the currency in your wallet when you don't use it, which is higher than the security factor in the exchange
wallet is actually used as an address protocol, because all transactions on the blockchain are recorded in the whole network. Every bitcoin transaction to an address is recorded in the whole network and cannot be tampered with. When bitcoin arrives in your wallet, everyone can see the record to prove it
unlike most traditional currencies, bitcoin is a digital currency. Therefore, the method of this kind of currency is completely different, especially when it is obtained and stored. Because bitcoin doesn't have any physical shape or form, it can't be stored anywhere technically. Instead, it is the private key used to access your public bitcoin address and sign transactions that need to be stored securely. The combination of the recipient's public key and private key makes bitcoin transaction possible
there are several different forms of bitcoin wallets, which can meet different needs, and are different in security, convenience, accessibility and so on
paper wallet
a paper wallet is essentially a document that contains a public address and a private key that can be used to receive bitcoin, allowing you to spend or transfer bitcoin stored at that address. These are usually printed in the form of QR codes so that you can quickly scan them and add the key to your software wallet for transactions
paper wallets can be generated using services such as bitaddress or bitcoinpaperwallet, allowing users to create completely random bitcoin addresses and private keys. The generated document can then be printed, some of which offer tamper proof design, and even can choose to order holographic tags and use them
the main advantage of banknote wallet is that the key will not be stored in any place in digital form, which makes it completely free from hacker attacks. It can record the malware users hit and basically any form of digital theft. However, some precautions still need to be taken when creating wallets
obviously, before generating a paper wallet, you need to make sure that no one is watching you. To eliminate the risk of any spyware monitoring activity, it is recommended to use a clean operating system running from a USB flash drive or DVD, such as Ubuntu
in addition, once the paper wallet is set up, the website code should be able to run offline, which allows you to disconnect from the Internet before actually generating the key. Finally, use a printer that is not connected to the network
in addition, it is very important to know that you are printing valuable personal information on a piece of paper. Therefore, you need to take some measures to protect that piece of paper. For example, it is suggested to put it in a sealed plastic bag to prevent water stop, moisture and general wear. Some people like to laminate it and store it in a safe, storage box or entrust a lawyer to handle it
physical bitcoin
physical bitcoin usually preloads a fixed number of BTCs, and the intention is that as long as the private key remains hidden, it cannot cost its value. This is usually achieved by implementing tamper proof seals
bitbill's first proct was like a credit card, but most of its subsequent substitutes were shaped into a round medal. Mike Cadwell, a cryptocurrency enthusiast nicknamed "casascius", created the first popular casascius physical bitcoin in 2011
the private key is hidden under the strippable hologram, and when it is removed, it leaves the tamper proof mode. In exchange, the coin lost its numerical value. Since then, there have been several new coin makers
physical bitcoin is a very convenient way to store your funds more safely, which is very useful in offline transactions. Most importantly, they have recently become a valuable collection. However, the main drawback is serious security issues
in November 2013, Mike Cadwell was asked to stop the operation of the financial crime enforcement network because his work was considered to be a money sender. The rules of the campaign were so overwhelming that he had to stop selling items containing digital bitcoin. Since BTC is still a legal gray area in many countries, these items may even be considered counterfeit by the authorities
mobile
BTC is an indispensable tool for those who actively use bitcoin every day to pay for goods or trade face-to-face in stores. It runs as a smartphone app, stores your private key and allows you to pay for things directly from your phone
in addition, some applications enable users to use their smartphone's near-field communication function, which means that they can simply click on their phone to oppose readers without having to provide any information at all
any complete bitcoin client needs to access the whole blockchain ledger, which is growing and needs several thousand megabytes of storage space. Therefore, mobile wallet uses simplified payment verification (SPV) technology. They only apply to a very small subset of the blockchain and rely on trusted nodes in the bitcoin network to ensure that they have the correct information
although bitcoin storage is a convenient mobile solution, mobile wallet is vulnerable to hackers. In addition, if someone just accesses your mobile device, you may lose control of the wallet. There are a variety of bitcoin wallet applications running on Android devices. Apple banned bitcoin wallets from the app store in February 2014, but withdrew its decision a few months later
Web wallet
Web wallet stores your private key on the server of the company providing such service. The server is always online and controlled by someone else. Different services provide different functions, some of which connect to mobile and desktop wallets to your address on the device you own
very similar to mobile wallet, e-wallet enables users to access their funds anytime, anywhere through any device connected to the Internet. But unless implemented properly, the organization that runs the site may access your private key and take full control of your money. In addition, some e-wallets operate on the basis of exchanges, and some exchanges close down and escape users' funds
Desktop wallet
Desktop wallet has been downloaded and installed on your computer, and your private key is stored on the hard disk. By definition, they are more secure than online and mobile wallets because they do not rely on third parties for data and are more difficult to steal. They are still connected to the Internet, which makes them inherently insecure. But desktop wallets are a great solution for those who trade a small amount of bitcoin from their computers
Desktop wallet has many different choices to meet different needs. Some focus on security, some focus on anonymity, etc
Hardware
Hardware wallet is a unique bitcoin wallet, which can store the user's private key in a secure hardware device. This is the safest way to store any amount of bitcoin, and there is no verifiable event that money is stolen from the hardware wallet
unlike paper wallets, paper wallets must import software at some time, and hardware wallets can be used safely and interactively. In addition, they are not affected by computer viruses, and the stored funds cannot be transmitted to output devices in clear text. In most cases, their software is open source
some hardware wallets even have screens, which adds another layer of security because they can be used to verify and display important wallet details. For example, the screen can be used to generate recovery phrases and confirm the amount and address of the payment you want to make. Therefore, as long as you invest in a real equipment with good reputation made by a reliable and competent manufacturer, your funds will be safe and reliable
bitcoin wallet and security
possible problems:
capture malware. Malware can scan your disk and find your private key. In a few seconds, all your bitcoins will disappear. Trojan can encrypt all the files on the hard disk. After that, it may find all the links to your wallet, realize how much money you have and ask for the exact amount of bitcoin to decrypt your hard drive
virtual exchange can use your money to escape. You can lose the laptop or mobile phone on which the wallet is installed
suggestions:
< UL >avoid using any wallet that needs Internet connection; Please use the refrigerated option instead
check everything carefully. For example, you can receive an email from blockwallet, but it's actually from blockcwallet, and if you authorize, your bitcoin will disappear immediately
7.4 purchasing
7.4.1 purchasing process
the organization shall ensure that the purchased procts meet the specified purchasing requirements. The type and degree of control over suppliers and purchased procts shall depend on the influence of purchased procts on subsequent proct realization or final procts
the organization shall evaluate and select suppliers according to their ability to provide procts as required by the organization. Criteria for selection, evaluation and re evaluation should be established. Records of the evaluation results and any necessary measures arising from the evaluation shall be maintained (see 4.2.4)
[note]:
(1) what are the purchasing requirements? Procurement requirements are generally those mentioned in 7.4.2
(2) "the type and degree of control over suppliers and purchased procts..." this sentence is a bit awkward. The popular one is to analyze how much the proct we purchased affects our own proction process, and how much it affects the quality and safety characteristics of the final proct, The implementation of procurement requirements are not the same. Generally speaking, the purchased procts are divided into three levels according to their importance: each level corresponds to different purchasing requirements
(3) the second paragraph is simple. How can we judge whether the supplier is good or not? Of course, we should formulate a standard for evaluating suppliers according to whether they meet our requirements and the degree of satisfaction, then evaluate our suppliers according to this standard, and finally record the evaluation content<
7.4.2 purchasing information
the purchasing information shall describe the procts to be purchased, including approval requirements for procts, proceres, processes and equipment when appropriate
personnel qualification requirements
requirements of quality management system
before communicating with suppliers, the organization should ensure that the specified procurement requirements are adequate and appropriate
[note]
(1) "approval requirements for procts, proceres, processes and equipment" lists some purchasing information that we must know, such as what kind of procts to purchase (proct category and characteristics, etc.) and what kind of proceres to purchase. Note that the following "approval of process and equipment" here refers to the supplier's process (which can be understood as process) and equipment for procing the proct. When the process and equipment need to be approved by the customer, the approval requirements must be specified (refer to PPAP "proction process approval procere" in the automotive instry).
(2) "personnel qualification requirements" here mainly refers to whether the supplier's personnel related to the proct meet the requirements
(3) "quality management system requirements" refers to the requirements of our purchaser for the quality management system of the organization supplying us, such as passing ISO9001, iso16949, Q1, etc., or passing the second party audit implemented by our purchaser
7.4.3 verification of purchased procts
the organization shall determine and implement inspection or other necessary activities to ensure that the purchased procts meet the specified purchasing requirements
when the organization or customer intends to carry out verification at the supplier's site, the organization shall specify the arrangement to be verified and the method of proct release in the purchasing information
[note]
(1) the first paragraph is very simple. What any enterprise is doing is an incoming inspection, qualified release, unqualified return or concession acceptance. There is nothing else to say, just pay attention to the inspection record
(2) the second paragraph is also very clear about the requirements when our purchaser requests to carry out proct inspection at the supplier's proction site. For example, I met a company procing automobile panels before. When he supplied procts to Chang'an company, the proct quality was very unstable and the unqualified rate was very high in a certain period, which greatly affected the proction of the main engine factory. At this time, Chang'an company sent their inspectors to guard the workshop of the company, staring at their personnel operation and inspection, and providing necessary help. Only after they are qualified can they leave the factory. What this paragraph says is this situation. It only emphasizes that when necessary, the problems involved in this situation should be written and agreed with the supplier
the above are the specific requirements of ISO9001 for purchasing. However, as a purchasing related person, it is better to understand the whole chapter 7 of the standard. After all, purchasing is for proction, and Chapter 7 is about proction
in addition, if a company's various proceres and systems are perfect, in fact, in terms of a certain position, it can completely ignore the standards, just learn the company's relevant proceres and systems well
in addition, OKC is the abbreviation of Oklahoma City. Oklahoma City
TJJ hopes to help you
OKC is short for Oklahoma City Thunder
Oklahoma City Thunder is a professional basketball team based in Oklahoma City, Oklahoma, USA. It belongs to the National Basketball Association (NBA). It joined the NBA in 1966 and is a part of the northwest division of the Western League of American men's Basketball League
the predecessor of Oklahoma City Thunder is Seattle SuperSonics. The team announced its new name: Thunder on September 3, 2008, and the team moved to Oklahoma City
{rrrrrrr}
extended materials:
from the name of NBA team, to see the human and geography of American cities
1, reflecting the climate and geographical characteristics:
Miami Heat: established in 1988, the team is located in Miami, Florida, which is warm and pleasant all seasons, so "hot" is selected in the list of many teams, It not only shows the climate conditions of Miami, but also hopes that the team can have a prosperous and prosperous future
2. Reflecting the local economic characteristics:
Detroit Pistons: when he joined the NBA in 1948, his base camp was in forwyne, and his boss was engaged in piston manufacturing instry. "Piston" became the team name of the team. In 1957, the team moved to the motor city of Detroit and still used the name. The world's first-class car companies, such as Ford, general motors and Chrysler, all set up factories here
3, reflecting the history of early European immigrants
New York Knicks: joining the NBA in 1946, the correct term is "the knickers", because there are a large number of Dutch immigrants in New York, the Dutch like to wear baggy knickers, and "Knicks" is just the translation of the word "the knickers"< The Denver Nuggets, formerly known as "Denver Rockets", is one of the founding teams of ABA. After joining the NBA in 1974, it was renamed "Nuggets team" because gold was discovered in Denver in the 19th century when the United States carried out the great development of the western region. Denver is rich in gold and other mineral resources

it can be seen that Oklahoma is only a small place compared with other big cities, and it is definitely not very poor.
