Mt.Gox公告：近期发生了什么事情？

尊敬的各位MtGox用户和比特币爱好者：

最近几日对于比特币来说是历史性时刻，比特币的价格上升到了142美元，我们希望这只是比特币发展新阶段的开始。

但是，我们发现有很多人使用各种办法滥用MT的交易网站获利，过去的几日这种事情非常明显。

MT经历了有史以来最严重的交易延迟，502错误，有些时段里，一些用户连登入都登不了。这些情况背后的原因是DDOS攻击。

从昨天开始，我们受到的DDOS攻击比以往更加严重，虽然我们有优秀的合作伙伴的支持，但是这一轮DDOS的数据量非常之大以至于我们每几个小时就得整理系统，以避免502错误和交易延迟。

为什么MT成为DDOS攻击的目标？

到目前为止，虽说这一轮DDOS攻击的发起者仍然不清楚，或许永远也无法彻底追查，但是这些DDOS攻击行为有两个目的：

第一，使得比特币系统不稳定。众所周知，MT是世界上最大的比特币交易所，因为MT的交易量占全球比特币交易量的80%和全部法币的70%。所以，MT就成为对比特币发起攻击的首选目标。

第二，谋取利益。攻击者先是把价格推高，出售，然后攻击系统造成不稳定从而制造恐慌，大众抛售，等到价格走低之后，他们又重新买入。过去几日我们看到几轮这样的操作。

我们能做什么？

作为服务供应商，我们能做到只是反击DDOS攻击本身。

比特币爱好者能做什么？

不要慌乱。

根据《维基百科》，“恐慌性抛售指的是大规模地出售产品从而导致价格暴跌，具体来说，就是投资者为了把一批产品脱手，不理会购入产品的价格是多少。恐慌性抛售行为之所以有问题，因为抛售者卖出产品的行为不是基于理性的价值评估，而是受制于一种恐惧的心理”。

很多人在比特币上做的投资额很大，但是恐慌是不必要的。虽然比特币从协议的层面看具备长期持有增值的能力，但是它也一直是某些人为了不当获利而发起攻击的目标。比特币的价格也会经常有波动和下降，自从比特币交易市场形成以后，这些都不是什么新鲜事。

关于交易延迟

交易延迟影响到每一个交易机构，不止是MT，就连世界上领先的Nasdaq和纽约证券交易所都不例外。我们可以修复交易延迟，但是无法根除。只有交易量非常小的交易所才有可能避免延迟发生的情形。

这样声明是否意味着MT对交易延迟不采取任何措施？完全不是。MT对于交易延迟采取的手段包括：更新交易引擎、增加服务器。外界的因素例如DDOS，恐慌性抛售和短时间内迅速增加的新的交易账户都能显著地增加数据量，MT一直在密切关注这些情况并采取积极措施。

用户身份认证

好像DDOS的攻击还不够让MT忙碌，用户身份认证也极大地增加了工作量。

随着MT业务的迅猛发展，MT从去年开始每个月平均新增用户有1万个，今年一月翻倍，二月增加了三倍，三月有5.7万个新增用户，增加了六倍。

客服部门负责客户认证的人员有2名增加到22名每周七天工作。我们现在正在通过业务外包的方式来雇员更多的人来完成这项工作。

最后，关于网上各种对MT的评论

网上对MT的各种评价非常多，有些人说MT很白痴，特别是抱怨MT无法处理交易延迟。

MT能够理解用户因交易延迟而产升到焦虑和恼火，MT自己也非常痛恨这种情形。虽然经历了很多的考验，但是MT依然健壮地运行着，MT依然是最大的比特币交易网站，每个月处理42万次交易，月交易额也保持在1.21亿美元。

对于每天支持MT的用户，我们表示感谢，没有用户的支持MT不可能发展到今天的水平。

MT全体同仁

公告原文：

It's been an epic few days: What happened?

TOKYO - JAPAN - April 04, 2013   Dear Mt.Gox users and Bitcoiners,  It’s been an epic few days on Bitcoin, with prices going up as high as $142 per BTC. We all hope that this is just the beginning!   

However, there are many who will try to take advantage of the system. The past few days were a reminder of this sad truth.  

Mt.Gox has been suffering from its worst trading lag ever, 502 errors, and at one point some users were not able to log in their account. The culprit is a major DDoS attack against Mt.Gox.   

Since yesterday, we are continuing to experience a DDoS attack like we have never seen. While we are being protected by companies like Prolexic, the sheer volume of this DDoS left us scrambling to fine-tune the system every few hours to make sure that things don’t go beyond a few 502 error pages and trading lag.   

Why has Mt.Gox become the target of a DDoS attack?  It is not yet clear who is behind this DDoS and we may never know, but these actions seem to have two major purposes:  

• Destabilize Bitcoin in general. It is not a secret Mt.Gox is the largest Bitcoin exchange with more than 80% of all USD trades and more than 70% of all currencies. Mt.Gox is an easy target for anyone that wants to hurt Bitcoin in general.  

• Abuse the system for profit. Attackers wait until the price of Bitcoins reaches a certain value, sell, destabilize the exchange, wait for everybody to panic-sell their Bitcoins, wait for the price to drop to a certain amount, then stop the attack and start buying as much as they can. Repeat this two or three times like we saw over the past few days and they profit.  

What can be done?  Believe it or not, there is pretty much nothing that can be done. Large companies are frequently victims of these kinds of attacks. Even though we are using one of the best companies to help us fight against these DDoS attacks, we are still being affected.  There are a few things that we can implement to help fight the attacks, such as disconnecting the trade engine backend from the Internet. By separating the data center from the Mt.Gox website, we will continue to be able to trade.  

What can you do? Like our favorite author here at Tibanne says… Don’t Panic!   “Panic-selling is a wide-scale selling of an investment which causes a sharp decline in prices. Specifically, an investor wants to get out of an investment with little regard of the price obtained. The selling activity is problematic because the investor is selling in reaction to emotion and fear, rather than evaluating the fundamentals.” (Source: Wikipedia)  I understand that many of you have a lot at stake here, but remember that Bitcoin, despite being designed to have its value increase over time, will always be the victim of people trying to abuse the system, or even the value of Bitcoin decreasing occasionally. 

These are not new phenomena and have been present since the beginning of time when humans first started trading.  

Trade Engine Lags Lag affects everyone, not only us, but also major, world-renowned exchanges like the NASDAQ and NYSE. We can fix lag, but we cannot eradicate lag. Only small exchanges with low volume and liquidity are immune to lag.   

Does this mean that we are giving up fighting lag? Hell, no. We are working on it by creating a new trade engine that will solve many problems, but it’s not a magic bullet. We can always try to scale our servers, but we cannot predict what happens from external sources: DDoS, panic selling, immediate increase of buyers, etc. Lag will always be there, but our mission is to make lag as small as possible.   

Account Verification As if a major DDoS attack was not enough, we at Mt.Gox are victim of our own success!  Last year, Mt.Gox saw an average of 9,000 to 10,000 new accounts created every month. This number doubled in January, tripled in February, and sextupled in March. In this month alone (March), over 57,000 new accounts were created!   

Our support and account verification team went from four people in January 2012 to twenty-two people working every day of the week. We are now hiring even more people to solve this problem by finalizing some deals with external companies.  

Remember that even if you are waiting for your account to be verified, you can still deposit or withdraw funds via our Japanese account and make your trades! (Only accounts that we pro-actively required to be verified are limited to deposits and trade only.)  

Finally We have seen a significant amount of comments on the web (various forums, Reddit, etc.) that portray Mt.Gox as a company held by “idiots” and other rather rude words, complaining about inability to deal with lag and other system issues, without understanding the magnitude of work and attacks we are facing every day.  

I understand the frustration many of you feel. We hate this situation as well. Since we took over Mt.Gox, we have been through Hell and back and we are still here. We are still the largest exchange with over 420,000 trades per month and USD $121 million monthly trade volume. We have worked our way through all the requirements needed to run our exchange legally.   

Now, there are some things we can improve, but so far we are doing an incredible job that no other exchange has been able to do so far. While I understand a certain amount of frustration, realize what we have accomplished. I appreciate all the work you are doing everyday to push things forward and to help secure the future of Bitcoin  And to all of you who are supporting us on a daily basis, thank you! We could not have done any of this without your help!

Regards

Mt.Gox Co. Ltd Team.
