黑客入侵最大美元比特币交易平台，币价单日暴跌25% - 比特币 - IT资讯
8月3日凌晨，最大的美元比特币交易平台Bitfinex发出公告，由于网站出现安全漏洞，导致用户多达119756枚比特币被盗，总价值约为7500万美元，暂时关闭比特币交易以及提现业务，从而引发国际国内市场的恐慌抛售。
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，比特币交易价格从最高4043元人民币下跌至最低3005元人民币。
相较暴跌行情，比特帀安全问题更引人关注。
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。由于比特币的匿名性，被盗后几乎无法追回。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。2014年8月15日，国内交易平台比特儿被黑客盗走5000万未来币（即NXT，Nextcoin），折合人民币约1000多万元，2015年2月15日又被盗7170枚比特币。2015年1月23日，Egopay交易系统被入侵，给用户造成120万美元的损失。
安全问题一直是比特币领域最大的威胁。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。比特币本身所具有的稀缺性及无国界等特点让其成为了天然的投资品。
据了解，Bitfinex此次安全漏洞还是在热钱包上。火币网联合创始人杜均表示，安全问题是考验全球比特币交易所最重要的关键之一。火币网从2013年开始就采用基于中国首个多重签名比特币钱包的用户资产分离方案，保证用户98%的比特币存储在多重签名冷钱包，只有2%的比特币存储在热钱包，极平衡了比特币的安全性和便利性。
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。但是要注意的是，如果存储冷钱包的硬件设施损坏，里面的比特币将会丢失。
热钱包是另一种存储钱包，一直联网，所以不用下载所有数据，只需连接网络即可。热钱包十分轻便，在相应网站注册一个帐号即可使用。但是安全系数较低。普通用户一般推荐使用热钱包，选择没有被攻击记录、可信赖的网站注册。
