Loss of Coin Due to 'Eubbit' Hacking, Bankruptcy Procedure

--------------------------------------------------------------------------------

The virtual currency exchange, Ubit, has decided to go bankrupt after suffering a coin loss from hacking. This is the first time that the virtual currency exchange is going bankrupt due to hacking in Korea.

"We lost the coin purse today because of the hacking at 4:35 a.m. today," Yubbit said on its website.

The company says there were no additional losses because the amount of coin losses from the hacking was about 17 percent of its total assets, while the other coins were stored in cold jails (outdoor storage systems disconnected from the Internet). "The management wants to proceed with the suspension of transactions, suspension of deposits, and bankruptcy on the 19th."

As of 2:00 p.m. on the same day, Yubbit told us that all coins and cash receipts will be suspended, and that due to bankruptcy, cash and coins will be settled in accordance with all bankruptcy procedures. To minimize damage, Yubbit said, "As of 4 a.m., 75 percent of the balance will be deducted in advance." The remaining outstanding parts will be paid after final settlement is completed.

"Our members are expected to lose more than 17 percent through a number of measures, including the sale of 3 billion won of cyber insurance and the company's operating rights," said Yubbit. Although the amount of damage will vary depending on the result of liquidation, the investors are expected to be opposed as they said that they should share the bankruptcy damage caused by the stock exchange hacking accident.

Previously, Yapian, the predecessor of Ubbit, was arrested in April for stealing 3,831 bitcoin (about 5.5 billion won at the time) and informed investors to share a total of 37 percent of the losses.

--------------------------------------------------------------------------------

This year alone, there was a case of Nice Hash hacking on the Coinz Exchange.

--------------------------------------------------------------------------------

In addition to the activation of coin trading, hacking damage has continued to threaten incomplete security systems.

In addition to Yapian, Coinaz was hacked last September, and the virtual money mining company, Nice Hash, posted on its Facebook account on July 7 (Korea time), saying that the electronic wallet of Nice Hashbitcoin was stolen (hacked) because of a security breach involving the company's website.

Nice Hash is a company that supports connection between Bitcoin miners and those who can devote computing capacity, and regularly pays Bitcoin to computing capacity providers.

--------------------------------------------------------------------------------

Member Information Disclosure, Server Down Cases

--------------------------------------------------------------------------------

In June, 36,000 members were leaked from Bithumb, the nation's largest bourse.

It's not a hack, but investors who suffered losses are preparing to sue Bithumb as his server went down on April 12 when the price of virtual money keeps soaring.

The soaring Bitcoin cash in November once fell to 1.3 million won worth of 2.85 million won when Bithumb's server went down.

--------------------------------------------------------------------------------

What to Pay attention to when dealing with virtual currency

--------------------------------------------------------------------------------

1. Security issues

While the exchange must be secure, it is recommended that private investors change their password management from time to time.

If you use multiple exchanges, using different passwords can confuse security issues. If one is hacked, the other can be hacked.

2. Strengthen OTP Security

If possible, it is advisable to do OTP security one more time.

3. Prevent Virus Penetration in Transactions

You should update your computer or mobile phone, a means of dealing with virtual money, to ensure that it is safe for malicious code and viruses.

We can't overemphasize the security issue of virtual money.

The virtual money market is a market with no lid or floor, and it goes up and down by a certain percentage per day. Behind the convenience of always doing business 24 hours a day, there is always a security issue, and I think it's necessary to pay attention to individual investors.

"U-BIT"黑客入侵导致COIN损失,进入破产程序

--------------------------------------------------------------------------------

虚拟货币交易所"U-BIT"因黑客攻击而遭受硬币损失,决定启动破产程序。 "这是国内首次因黑客入侵而使虚拟货币交易所进入破产程序。"

19日,U-BIT通过主页表示:"今天上午4点35分,因黑客入侵,硬币出钞钱包出现了损失。"

公司表示,黑客入侵造成的硬币损失额约占总资产的17%,此外硬币还保管在电脑钱包(与网络隔绝的外部存储装置),因此没有追加损失。 同时,他还表示:"经营团队将于19日启动中断交易,停止存取款措施及破产程序。"

当天下午2点,U-BIT向我们介绍,所有Coin和现金的进出被停止,由于破产,现金和Coin的清算将按所有破产程序进行。 尤比特解释说,"但为了减少损失,以当天上午4时为准,将采取措施,使余额的75%可以提前出纳。" 剩下的未支付部分,将在最终整理完毕后支付。

尤比特补充说:"通过公司加入的网络综合保险(30亿韩元)和出售公司经营权等各种方案,预计会员的损失额将比17%更低。" "虽然根据清算结果损失规模不同,但这是虚拟货币投资者们要分担交易所黑客事件导致的破产损失,因此预计将会引起投资者们的抗议。"

此前,U-BIT的前身——Yapian在今年4月因黑客攻击被抢走3831个(当时标准约55亿韩元)beat coin后,曾公开要求投资者分担高达37%的损失额,引发了争议。

--------------------------------------------------------------------------------

仅今年就发生了Koin Is交易所,Nice Hash黑客事件。

--------------------------------------------------------------------------------

随着硬币交易的活跃,威胁不完整的保安系统的黑客灾害持续发生。

除了(株)yapian之外,9月koin is交易所也遭到黑客攻击,虚拟货币开采公司"nice ash"7日(韩国时间)在facebook上发布了相关文章,称"公司网站"。

Nice Hash是支持Betcoin采矿者与可进行计算容量的人之间的连接的企业,定期向计算容量提供者提供Betcoin。

--------------------------------------------------------------------------------

会员信息泄露,服务器瘫痪事例

--------------------------------------------------------------------------------

今年6月,韩国国内最大的交易所Bisom还泄露了3.6万多名会员信息。

虽然不是黑客攻击,但是上个月12日虚拟货币价格反复暴涨暴跌时,Bisom的服务器瘫痪,无法应对暴涨暴跌而蒙受损失的投资者们正准备起诉Bisome。

11月暴涨的BetcoinCash随着Bisom服务器的瘫痪,285万韩元的价格降到了130万韩元。

--------------------------------------------------------------------------------

虚拟货币交易时要注意的一点

--------------------------------------------------------------------------------

1. 安全问题

交易所的保安应该彻底,但是个人投资者也应该随时变更密码管理。

使用多数交易所时使用其他密码可能会引发安全问题。 因为如果一个地方被黑客攻击,另一个地方也有可能被黑客攻击。

2. 加强OTP保安

最好再做一次OTP保安。

3. 防止交易手段的病毒渗透

必须随时更新虚拟货币交易手段电脑或手机,以确保恶性代码及病毒安全。

虚拟货币的保安问题是不言而喻的。

虚拟货币市场是一个没有盖子和底子的市场,每天上下浮动着百分之几。 考虑到在24小时可以经常进行交易的便利性背后,保安的问题也总是存在的,因此需要提醒投资者个人注意。

Unlike stocks, bitcoin transactions do not have a cap or a lower limit, but they can be traded for 24 hours without opening or closing time, so I think we can understand the increase and decrease of the current coin price compared to the previous day.)

Considering the rate of increase and decrease in bitcoin prices in stock market analysis, it seems that money is flowing.

Some even say that Korea's bitcoin craze is bubble phenomenon, speculation, not investment, and gambling, but one reality that is coming to us at this point is undeniable.

So let's take a look at the origins of virtual money.

--------------------------------------------------------------------------------

The origin, distribution, and the listing of the U.S. futures market...

--------------------------------------------------------------------------------

It's not clear who made the bitcoin.

A user named Satoshi Nagamoto was active on bitcointalk.org and a computer student named Marti Malmi of Finland was the domain owner of bitcoin.org, a site that officially distributes Bitcoin.

(This is the book 'Learn New Bitcoin Easy').

The use of the units called Satoshi suggests that they are more likely to be electrons.

Anyway, if you look at the context of the age when virtual money came into being,

In the midst of the 2008 financial crisis, the collapse of the subprime mortgage system pushed existing monetary systems to their limits, and the government and the central bank chose quantitative easing, but the falling value of money led to a greater crisis and led to the emergence of virtual money in those concerns.

In the early days of Bitcoin, offline stores also increased rapidly with the possibility of encoding money, but the price of bitcoin increased rapidly, making transmission fees unsuitable for small transactions and not active due to lack of access to real life, transmission time, etc.

However, the advantage of cheap fees for international remittance and the fact that it is available in areas where financial networks are not developed, the strength of large amounts of money used for international transmission or storage is expected to continue to increase.

Bitcoin prices have been soaring and plummeting due to various issues in Russia, China and other countries, but blockchain technology has been under re-lighting and has been rising in earnest since 2016.

In September 2017, it soared to $4,970 and now that it's officially traded like gold in the U.S. futures market, we'll have to see how much of the price we're at this point.

Less than a decade after Bitcoin's birth, the world's attention seems to be on its way to the heart of the global financial market.

The Chicago Board of Options (CBOE) in the U.S. will begin trading its first futures contract on December 10 with Bitcoin as its underlying asset. The Chicago Board of Trade (CME) plans to list bitcoin gifts on the 18th. You're officially debuting in the U.S. futures market. That's why Bitcoin prices have been rising recently.

When listed on the Chicago Mercantile Exchange, it takes systemic stability, such as the introduction of a device that temporarily suspends futures trading with a range of price limits during the day to buffer sudden fluctuations in prices, the transaction is suspended for two minutes when the market price reaches 7% and 13% compared to the previous day's closing price, and orders with a rate of more than 20%.

In the United States, futures investment in cryptography became possible, but in Korea it is temporarily prohibited.

All right. Yesterday, an official at the Financial Services Commission said, "The capital market law ruled that bitcoin does not apply to basic assets, so domestic financial institutions were not allowed to open derivatives."

However, as you know, many people say that it remains to be seen how much impact it will have on the domestic capital market since encryption money is a global exchange method.

Next time, we will learn how to trade virtual currency, how to deal with it, how to pay attention to it, and how to invest. Thank you very much.

Betcoin交易与股票不同,没有涨停板,跌停板,但开盘/停牌时间不长,交易时间24小时,因此可以理解为与前一日相比,现点Coin价格的增减率。)

分析股市时,也考虑到了比特币价格的增减率,看来钱的流向是真的吗?

有人对韩国的"维特克人"狂风说:"这是泡沫现象,不是投资,而是投机,是赌博。"

好,下面我们从虚拟货币的由来开始一一了解。

--------------------------------------------------------------------------------

从虚拟货币的由来,推广到美国期货市场上市......

--------------------------------------------------------------------------------

据说,还没有确切查明是谁制造了比特币。

一个名叫佐藤长本的用户在 bitcointalk.org上活动,一个学习计算机的学生,因为是正式发布Vitcoin的网站 bitcoin.org的域名所有者而产生的议论......

(这是《易学新变的维特克人》一书的内容),

从使用佐藤市这一单位来看,电子的概率很高。

总之,从虚拟货币出现的时代背景来看,

在2008年金融危机中,由于次级抵押贷款的崩溃,现有的货币系统已经达到了极限,政府和中央银行虽然选择了量化宽松政策,但由于货币价值下降,出现了更大的危机,在这种担忧中出现了虚拟货币。

比特币初创期,对加密货币的可能性,线下加盟店也迅速增加,但由于比特币价格上涨,传输手续费不适合小额交易,而且由于实际生活接触性不足,传输时间等原因,无法激活。

但是,由于国际间汇款时手续费便宜的优点和可以在金融网络不发达地区使用的优点,可以作为大金额的国际传送或储存用邮资的优势将会持续增加。

比特币的价格因俄罗斯,中国等多个国家的各种问题暴涨,暴跌,积木技术开始重新受到关注,从2016年开始正式上涨。

2017年9月曾升至4970美元,据说在美国期货市场上像黄金一样正式交易,现在看来,时间点在价格的多少位置还有待观察。

"在比特币诞生不到10年的时间里,作为世界金融市场的心脏,似乎受到了全世界的关注。

美国芝加哥期权交易所(CBOE)将于12月10日开始以Betcoin为基础资产的首次期货合约交易。 芝加哥商品交易所(CME)计划18日上市。 即将正式进军美国期货交易市场。 在这样的背景之下,最近好像正在发生维特科因价格上涨的现象。

在芝加哥商品交易所上市时,为了缓冲价格剧变,引入了在盘中暂时中断价格限制幅度的期货交易的装置,与前一天收盘价相比,市价如果达到上下7%和13%,交易将中断2分钟。

在美国可以对暗号货币进行期货投资,但在韩国暂时禁止

昨天,金融委员会相关人士表示:"根据资本市场法,betcoin不属于基础资产,因此不允许国内金融机构进行衍生商品中介。"

但是,很多人认为,正如您所知,密码货币是全球流通的交换手段,因此对国内资本市场产生多大影响还有待观察。

接下来我们将一起学习虚拟货币的交易方法,交易时的注意事项,投资标准等。 谢谢。

In the midst of a whirlwind of economic changes this year, including economic progress and housing market regulation...

As a person who lives in the same generation with a lot of talk and a lot of issues, I decided to take a bitcoin-related concept one by one because I thought I'd have to go through it.

Although there are various blogs and Internet information regarding Bitcoin, I decided to explore the books that are relevant because I need to understand the basic concepts first.

First, when I looked around the bookstore, there were many different books, such as virtual currency, encryption money, block chain, etc.

Among them, I chose a book recently written by Bitcoin community operators called 'Learn New Bitcoin Easy.'

It is a simple chapter that is described by subject, and it is a great introduction to the basic concepts and processes of various types of virtual money.

In addition, there are many blogs about virtual money, so it won't be difficult to get information if you sell a little bit of your hand

So, let's start studying now.

What is Bitcoin, virtualization money?

Turns out, Bitcoin is the blacksmith of virtual currency.

Virtual currencies are also perceived by the word 'virtual'.

The exact name is Crypto curacy.

That is, a means to create new coins or to make transactions secure using a password.

There are a lot of different types of encryption. Based on the total amount of encryption money currently traded in Korea, Bitcoin, 2nd place and Iderium are ranked first. So when people think of virtual currency, they think of bitcoin.

Types of Virtual Money

There are thousands of different types of virtual money all over the world. This is because mining methods and uses vary by type, depending on the purpose of the transaction, and therefore there is a variety of virtual currencies.

Let's take a look at the types of virtual currencies that are listed in Korea.

The table above is scraped from the Bithumb site.

In short, there are different types of bitcoins that can be traded on every exchange of virtual money.

In other words, bitcoin and iderium are all treated by most virtual money exchanges, but Monero and Dash need to go to 'Bithumb' and NEO need to go to 'Coin Nest' to buy/sell.

Virtual currency exchange refers to an exchange where virtual currency can be traded, and we will discuss it in more detail later.

Let's take a quick look at the concept of typical virtual money.

(This is a scrap from the Bithumb site, and there is more and more professional information available on the official site for each virtual currency, so please refer to it if you need it.)

--------------------------------------------------------------------------------

Bitcoin units: BTC
Bitcoin is the first encryption currency developed by Satoshi Nakamoto.
The maximum number of issues is 21 million and as of May 2017, 16.15 million were issued.
The average/final confirmation time is 10 minutes/60 minutes, which enables fast and safe transactions among individuals without financial institutions.

--------------------------------------------------------------------------------

Etherium (ETHEREUM) units: ETH
Iderium is an encryption currency introduced by Vitalic Buterin, a Russian Canadian, on July 30, 2015.The maximum amount issued with mining-type coins based on blockchain technology is unlimited. As of April 2017, the amount issued is 90.95 million.

--------------------------------------------------------------------------------

Dash (DASH)
The dash is an encrypted currency developed in January 2014 and is a platform.It was also called Xcoin and DarkCoin, but was finally named 'Dash' in March 2015. The maximum number of issues is 22.5 million and the confirmation time is 2.5 minutes on average.

--------------------------------------------------------------------------------

Light Coin (LTC)
Lightcoin is a virtual currency developed by Charles Lee, a former Google employee, on October 7, 2011.The technical aspects of light coins are almost identical to bitcoins.However, it was developed with the goal of becoming a better virtual currency by compensating for the shortcomings of bitcoin.

--------------------------------------------------------------------------------

There are also many other types of virtual currencies, including bitcoin cache (BCH), bitcoin gold, and ETC (Eitherium Classic) created by hardfork of Iderium.

The detailed concepts, technical descriptions, and characteristics of each virtual currency are listed in detail on the virtual currency exchange or on the official site of each virtual currency, so you can find them if you need them.
We learned about basic concepts such as concept and type of virtual money. Thank you very much

今年一年,在经济刺激,住房市场调控等诸多经济变化的漩涡中......

话很多,问题也多对虚拟货币的时代,同以人为他过去的想法,相关概念,电子货币的一个抓看来,吃了。

关于beat coin,虽然有很多博客和网络信息,但由于要熟悉基本概念,所以决定阅读相关书籍。

首先逛书店,发现里面有很多虚拟货币,暗号货币,模块链等多种书籍。

从中选出了Beatcoin社区运营者最近写的书《新变化的Beatcoin轻松学习》。

该书按主题进行叙述,结构简约,是一本可以学习多种虚拟货币的基本概念和程序的概论书。

此外,还有很多以虚拟货币为主题的博客,只要稍微尝试一下,获取信息应该不难。

好,那就从现在开始学习吧。

比特币,什么是虚拟货币?

原来,beat coin是"虚拟货币"的代名词,代表项目。

虚拟货币也因为"虚拟"这个词而有不明确的认识,

正确的名称是"暗号货币(Crypto currency)"。

即指使用密码生成新的硬币或确保交易安全的手段。

这种暗号货币种类很多。 以韩国现在交易的暗号货币价格之和总额为基准,第一位是比特币,第二位是伊德林。 所以人们一提到虚拟货币,即加密货币,就会想起比特币。

虚拟货币种类

据说全世界有数千种虚拟货币。 这是不同种类的采掘方式,用途不同的特性,即根据交易的目的不同,方式也会有所不同,因此虚拟货币的种类只能多种多样。

那么,我们来看一下在韩国上市的虚拟货币种类。

上面的表格是从Buisom Sat中剪下来的。

补充说明,每个虚拟货币的交易所都可以交易的比特币种类不同。

也就是说,虚拟货币中的比特币或易买得币在大多数虚拟货币交易所都有涉及,但莫内罗,大市等是"比特币"交易所,NEO是"可买可卖"的虚拟货币。

虚拟货币交易所是指可以进行虚拟货币交易的交易所,对此以后将详细讨论。

下面我们简单介绍一下具有代表性的虚拟货币的概念。

(本内容为Buisom Sats 剪贴,登录各相关虚拟货币的官方网站后会发现更多,更专业的信息,需要者请参考)

--------------------------------------------------------------------------------

Bitcoin单位: BTC
比特币是"中本聪(化名)"开发的最早的暗号货币。
最大发行量为2100万个,以2017年5月为准,发行了1615万个。
平均/最终按压时间为10分钟/60分钟,与现有货币不同,无需金融机构,可快速,安全地交易给个体。

--------------------------------------------------------------------------------

Etherium (ETHEREUM) 单位: ETH
Iduleum是俄罗斯裔加拿大人Bitalic Butterine于2015年7月30日引进的密码货币。基于积木链技术的采掘型硬币,最大发行量无限制,以2017年4月为准,发行量为9,095万个。

--------------------------------------------------------------------------------

DASH
大市是2014年1月开发的加密货币和平台。也被称为Xcoin和DarkCoin,但2015年3月最终被命名为"大市"。 最大发行量为2250万个,按压时间平均需要2.5分钟左右。

--------------------------------------------------------------------------------

浅硬币 (LTC)
"Light Coin"是2011年10月7日由前谷歌职员查尔斯•李(Charles Lee)开发的虚拟货币。浅色系的技术层面几乎与非特质相似。但是,我们的目标是弥补比特币的缺点,成为更好的虚拟货币。

--------------------------------------------------------------------------------

除此之外,还有从Bitcoin中分离出来的(链分离:硬盘)BCH,Bitcoin Gold,Edolium的硬包装(Hard)等。

对各虚拟货币的详细概念,技术说明,特性在虚拟货币交易所或虚拟货币的官方网站上都有详细记载,如有需要,请查阅即可。
以上是关于虚拟货币的概念,种类等基本概念。 谢谢。
