Two days ago, Bitfinex said in a statement on the currency exchange nearly 120,000 stolen silver coins hack , worth about $ 75 million, affected by this, global currency prices fell 25%. However, a Black Swan event does not blow on the market too much. Yesterday, the currency bounced back, recovering most of its losses.

Bitfinex Exchange said on its website: "today we discovered a security vulnerability on the Bitfinex platform, this has to make us stop Bitfinex all transactions, we will suspend the full coin coin business. We also know that some users of coins had been stolen, we are investigating on this vulnerability to determine which users are affected. ”

After the announcement the day before yesterday, bitcoin security problems on the selling of currency prices plunged, bracing for the biggest drop in this year. According to domestic currency trading platform fire money network offers shows, following the 6-day consecutive decline, currency trading day from highest to lowest 3005 Yuan RMB 4043 decline .

But shortly after the crash the day before yesterday, currency rebound in prices began to pick up, and continues to maintain that trend yesterday. As of yesterday afternoon, the Beijing Youth daily reporter, fire money net bit coin prices have rebounded to 3770, distance the day before yesterday, the highest point is just more than 220 Yuan, low bounce than 25% than the crash the day before yesterday, recovered most of their losses.

Compared with collapsed boom market, the stolen bit zad security concerns again. Due to the anonymity of the bitcoin, barely recovered after being stolen. Once stolen, will give the bitcoin owners and caused huge losses.

It was reported that in the past 5 years, 95% collapse of currency-related project is due to the currency were stolen. As early as February 28, 2014, was the world's biggest currency trader Mt.Gox filed for bankruptcy, claiming that due to hacking, lost at least 850,000 gold coins, as well as $ 65 million in debt.

Previously, financial College in Tsinghua University in wudaokou, fire coins network and SINA science and technology jointly issued the 2014-2016 coins in the world development report points out that currency price fluctuations, security, criminal use bitcoin development is the common debate.

It is understood that Bitfinex the security vulnerability is still hot on the wallet. Cool wallet and heat two storage wallet purse is bitcoin. Cool wallet that is not connected to wallets. When users download cool wallet, bitcoin network needs to be completely downloaded from the beginning up to now all the data, currency, disconnected from the network. Cool wallet very high security, for technical operations professionals. But if the stored cold purse hardware damage, coins will be lost. Hot wallet has networking, need to download all the data. Hot wallet is very simple, in the appropriate website to register an account to use. Safety factor is low.

前日，比特币交易所Bitfinex发布公告称近12万比特币银黑客攻击被盗，价值约7500万美元，受此影响，全球比特币价格应声下跌25%。不过，这一黑天鹅事件并未对市场打击太深。昨天，比特币强势反弹，收复了大部分失地。

Bitfinex交易所当天在其官网上表示：“今天我们在Bitfinex平台上发现了一个安全漏洞，这不得不使我们停止Bitfinex的所有交易，同时我们也将暂停充币提币等业务。我们也知道一些用户的比特币已经被盗，目前我们正在就此漏洞展开调查，以判断哪些用户受到影响。”

前日消息公布后，比特币安全问题带来的抛售使当日币价再次暴跌，迎来今年来的最大跌幅。据国内比特币交易平台火币网报价显示，继6天连续下跌后，比特币交易价格当日从最高4043元人民币下跌至最低3005元人民币。

但是前日暴跌后不久，比特币价格就开始回升反弹，昨天也仍然保持这一走势。截至昨天下午北京青年报记者发稿时，火币网比特币价格已反弹至3770元，距离前日最高点仅220多元，比前日暴跌的最低点反弹超过25%，收复了大部分失地。

相较暴跌暴涨行情，此次被盗事件使比特帀安全问题再次受到关注。由于比特币的匿名性，被盗后几乎无法追回。一旦被盗，会给比特币玩家和平台造成巨大损失。

据报道，过去5年中，95%倒闭的比特币相关创业项目都是由于比特币被盗。早在2014年2月28日，曾是世界最大比特币交易商的Mt.Gox申请破产，声称因黑客入侵，丢失了至少85万枚比特币，同时还负债6500万美元。

此前，清华大学五道口金融学院、火币网和新浪科技联合发布的《2014-2016全球比特币发展报告》就指出，比特币的价格波动、安全、犯罪用途是比特币发展过程的常见争议。

据了解，Bitfinex此次安全漏洞还是在热钱包上。冷钱包与热钱包是比特币的两种存储钱包。冷钱包即不联网的钱包。用户在下载冷钱包时，需要将比特币网络从开始到现在的所有数据全部下载下来，将比特币转入，断开网络。冷钱包安全性非常高，适合懂技术操作专业人士使用。但如果存储冷钱包的硬件设施损坏，里面的比特币将会丢失。热钱包则一直联网，不用下载所有数据。使用热钱包十分简便，在相应网站注册一个账号即可使用。但是安全系数较低。
