西安警方日前成功破获一起网络“黑客”盗窃虚拟货币案件，涉案金额高达6亿元人民币。破获这起案件历时半年多，破案的经过如何？虚拟货币到底哪里不安全？持有虚拟货币又该注意哪些安全问题？
      今年3月30日，西安市公安局经开分局接到一名张姓男子报警称，他的个人电脑疑似被非法入侵，大量虚拟货币一夜之间被洗劫一空，其市值达上亿元。西安市公安局经开分局凤城路派出所所长张现利说，因为案情巨大，这被认为是陕西省多年来从未发生过的计算机犯罪。

      案件立即引起了公安机关的高度重视，陕西省公安厅将此案列为挂牌督办案件，西安市公安局立即成立专案组，全力展开侦破。西安市公安局刑侦局反诈中心主任贾焘说：“我们也借鉴了很多国内外的案例，主要是追踪虚拟货币的流向，很多是在境外，需要去协调；另外还有外文的资料，需要翻译研究。”

      在侦查中民警了解到，犯罪嫌疑人通过网络黑客技术，在受害人没有任何操作的情况下，远程控制并盗取安全性较高的虚拟货币账户，而且几乎没有留下任何作案痕迹，让案件的侦破陷入困境。

      专案组通过各种渠道广泛协调沟通，通过虚拟货币的流向发现，涉案资金不断被拆分、层层转移。根据这一轨迹，警方先后调取了三万多条线索，进行筛选研判、排查分析。先后奔赴多个省市，行程达2万多公里。经过三个月的努力，专案组终于捕获到一条突破性线索，嫌疑人周某浮出水面。西安市公安局刑侦局民警卫元祥介绍说：“一直追查了很久，动用了很多资源，(获得了)国内外很多平台的协助。哪些用于转移赃款，哪些用来洗币、提币，我们全部查清了。”

      随后，专案组立即围绕周某展开了两个月的工作，最终锁定了团伙的其余两名成员崔某和张某，两人分别在北京、长春等地活动。西安市公安局刑侦局副局长党凯军介绍说，三名嫌疑人活动在不同省市，相隔千里，且他们为高智商犯罪团伙，反侦查意识极强。专案组为确保收网行动成功，多次召开专案会议，反复推敲抓捕方案。8月初，专案组兵分三路赶赴湖南、长春、北京，开展抓捕工作。

      今年8月15日，在掌握了大量证据后，抓捕时机成熟。在湖南、长春、北京警方的配合下，陕西警方的三个抓捕组同时展开抓捕行动，三名嫌疑人全部落入法网。在大量证据面前，犯罪嫌疑人对犯罪事实供认不讳。

      党凯军说，经审查，三名嫌疑人均为高级黑客，曾供职于国内知名网络科技公司，曾多次通过互联网非法入侵、控制公司企业和个人网络系统，获取非法收益，初步查明涉案金额达6亿元。目前，案件仍在进一步审理当中。

      比特币等虚拟货币基于区块链，具有去中心化结构，用户通过一个公开的地址和密钥来宣示所有权。从某种角度来说，谁掌握了密钥，谁就实质性地拥有了对应地址中的比特币资产。而区块链中的防篡改特征，是指比特币的交易记录不可篡改，而非密钥不会丢失。这也意味着，一旦密钥丢失，便不可能通过修改区块链记录来拿回比特币。

      卫元祥介绍，一般可使用物理隔绝和采取多签方案的方式将虚拟货币被盗风险降到最低。物理隔绝就是用户存放钱包的介质有可能是电脑也有可能是硬盘，尽量不要连上互联网，尤其是在互联网上进行操作的电脑，例如进行聊天、社交以及一些娱乐行为的电脑。多签方案就是针对一个钱包可能有多个密钥，例如用户有四个密钥，就可以设定当两个或者三个密钥同时允许时，钱包里的比特币才能转出去。此外，如果用户有多个密钥，应该分开存放，且分开存放的介质不要连到一个网络里。

自从币圈开始混乱，这种现象越来越多，到底有没有办法杜绝这种的事情发生？

    美国海关与边境保护局（CBP）计划试用区块链技术，以核实北美自由贸易协定（NAFTA）和中美洲自由贸易协定（CAFTA）证书。CBP业务转型与创新部门负责人Vincent Annunziato表示，该机构正在开始对区块链平台进行“实时火灾测试”，以证明进口产品源于他们在亚特兰大CBP 2018年贸易研讨会期间声称的产品，据美国托运人称。
他说，新系统将于9月推出，旨在帮助CBP核实有关进口货物的信息，并检查外国供应商如何对美国进口商采取行动。该系统还可用于验证商标并检查商品的物理属性。

     “我甚至可以进去说，'嘿，我需要关于缝合的一些信息，'或'我需要有关什么颜色可行的信息，'”Annunziato说。

      Annunziato表示，区块链系统可用于移动应用程序，该应用程序将取代基于纸张的手动过程以验证此类信息，从而简化机构的工作。
     
      他还介绍了该机构与商业海关业务咨询委员会（COAC）合作的最新情况。正如CoinDesk先前报道的那样，COAC于去年11月成立了一个专门小组，负责就该机构的商业运作向财政部和国土安全部长提供咨询。据说该机构一般侧重于新兴技术，特别是区块链。

      本周，Annunziato确认委员会正在努力开发一个概念验证区块链平台，通过确认被许可人和许可人之间的关系来验证知识产权。CPB希望，该技术最终可以消除纸质流程，手册和数据库。
      截至记者发稿时，CBP新闻办公室没有回复评论请求。

As part of the currency mix, cryptocurrencies are more in line with the “typical speculative bubble” behavior. South Korea and Japan dominate the bitcoin trade, but they are also countries with a stable monetary system.
The reality is that in most places, cryptocurrencies still have very high thresholds. First, the government cannot track who is buying or selling bitcoin. And as we all know, the price of cryptocurrency is very prone to large fluctuations.
This range of volatility is very rare in fiat currencies, so Bitcoin is currently not suitable as a reserve currency.

     According to coindesk, the California Fair Political Practice Committee met on Thursday to discuss whether the campaign can accept digital currency donations.In opposition, committee member Nicolas Heidorn suggested allowing campaigners to accept digital currency contributions after further research on digital currency.The Committee does not agree with this recommendation.
     Among the members who support cryptocurrency, Allison Hayward is the most prominent.She opposed a total ban on digital currency, and she said she particularly hated to ban digital currency from becoming a campaign fund before she did not investigate it, and she believed that blockchain technology would eventually become a powerful tool in trading behavior.
     Both Brian Hatch and Frank Cardenas believe that digital currency should not be completely banned, but if this proposal is accepted, the ensuing fraud becomes the biggest problem. The committee did not reach a final conclusion and will continue discussions next month.

不知道多少个小号去写这个东西了 ，全靠蒙？

适当的给自己灌输一些知识，假装不是个韭菜。

日常催眠自己。

赞同你的观点，炒币只是动作，哪怕不懂区块链的知识，不知道比特币是什么，也不一定会导致炒币失败或成功。
其实学习这方面的知识都是为了自己。
那炒币的人，跌还是涨全靠自己的把握，有钱人炒币就是撒撒水，没钱的人自然提心吊胆。
全靠心理素质和经济实力。

 在数字资产上赚大钱的人，他们大都是这样的：

1、对于新事物持开放心态，保持好奇心，快速尝试，第一时间接触财富机会。

2、由于新事物的风险都较高，采用闲钱投资，即比较安全，也让投资决策更加理智。

3、独立思考，不懂不投，把每个资产都了解清楚，搞清楚价值、团队和估值。

4、要么不买，要买就买多一点。如果钱不多，筹码一定会尽量集中，甚至做到流通量的千分之一。

5、耐心！耐心！他们都很有耐心！如果估值过高，他们会留着子弹，耐心等待进场时机；如果决定入手，他们会长期持有，不到趋势性颓势不脱手。



 

It is translated, so there are some better explanations for everyone to improve.

Hash Rate：The unit of measure for the processing power of the Bitcoin network, expressed in seconds.

POW：The "number of times a mining machine can make a hash collision per second" is usually called the calculation power. 1P computing power (1P = 1024T, 1T = 1024G) is equivalent to 1.05 million G. This means that if you have 1G of total network computing power, you can get almost one-thousandth of the bitcoin produced by the whole network. Based on Bitcoin's daily output of 3,800 calculations, 1G computing power per day is about 0.0036 bitcoins.

Blockchain：Is a public list of all transactions that have been sent, which ensures that everyone knows the true owner (address) of each bitcoin. A full-featured node on all networks maintains a copy of the blockchain.

Multisig:A technology that allows multiple public keys to jointly sign a bitcoin transaction. With this technology, it takes a lot of private keys to sign and verify when it is spent on Bitcoin, which is then accepted by the Bitcoin network, thereby improving Bitcoin's safety.

Transaction Fee:Each bitcoin transaction receives a certain transaction fee from the payer. Transaction costs typically account for a small portion of Bitcoin transactions and are a reward for mining miners.During the mining process, the miner dug a data block, and in addition to the bitcoin rewarded by the block itself, the transaction fee income can be obtained.

Mining:The process of consuming computing resources to process transactions, ensuring network security, and maintaining the synchronization of information for everyone in the network is similar to gold mining.It can be understood as a bitcoin data center, miners can operate in countries around the world, no one can have control over the network.

Ballet:Refers to a lightweight browser-based online management service, or a file containing the owner's bitcoin address and the corresponding private key needed to use those addresses.Similar to a bank account, in the world of Bitcoin, the bitcoin address is equivalent to a bank account number, the bitcoin private key is equivalent to the password for opening the account, and an address (account) corresponds to a private key (password), missing any element. Can't move the bitcoin in the wallet.

Private Key:A key associated with an address (this address is the hash of the public key corresponding to this private key).Applications that support the Bitcoin protocol can convert the private key of Bitcoin out of the public key and get an address. If there is a corresponding bitcoin on the address, you can use the private key to spend the bitcoin, which is dug up. "mine".

AML/KYCrule:The government has established a regulatory framework for digital currency (anti-money laundering / understanding of your customers) in order to prevent criminals from illegally using tokens.

Every country has its own legal currency, and the government does not like things that are beyond control.
Bitcoin is the world, no one can grasp it, this is decentralization.
Of course, because some people currently use Bitcoin for illegal activities.

我目前交易的交易所有火币和币安，不管怎么样，平台大一些总比不了解的小平台好，为了自己的资金安全，一定要选择对的交易所进行交易。

我有很好的几个办法：
1，清空离场牛市再见
2，一把梭哈坚持抄底
3，删除钱包远离行情

大概是中国作浪的太多了，所以要选择在我们睡觉的时候动。这样才能割更多的人？
我虽然猜的啦，其实在我们这是凌晨，但是在国外不是啊。

The Jamaica Stock Exchange (JSE) will soon be offering cryptocurrencies as tradeable assets for clients.

The company said Tuesday that it had signed a memorandum of understanding (MoU) with blockchain startup Blockstation for the creation of a new digital assets trading platform. While it is not clear which tokens will be initially listed, the platform is set to go live by the end of the year.

In interview, JSE managing director Marlene Street Forrest said that offering cryptocurrencies as investment products fits in with the equities, bonds and other investment products that the exchange already offers.

Forrest told CoinDesk:

"The end game at the end of the day is to trade tokens, the end game is smart contacts, the end game is to provide that area of the market that would like this product, to start to do so in a secure manner."

Blockstation is providing the technology, she explained, while the JSE's infrastructure will be networked to the new platform, allowing qualified investors to conduct purchases or trades.

Aside from listing cryptocurrencies for trade, Street Forrest said the stock exchange will continue to look at how blockchain technology can benefit the platform and its clients, going so far as to indicate that JSE's plans may include issuing its own cryptocurrency at some time in the future.

"The environment changes, the entire ecosystem changes, so at that point in time that might be the case, [although] at this point in time that is not a discussion," she said.

Blockstation co-founder and chief enterprise architect Jai Waterman told CoinDesk that the startup has been working with the JSE for roughly six months in order to develop a custom version of its platform for the exchange. Specific requests from the JSE have included tools to track market manipulation and other regulatory needs, he noted.

"Our mission is to provide … a secure method of trading cryptocurrencies with broker-dealers and stock exchanges," he said. "We're providing the stock exchange the technology for a broker-dealer network and repository, so that from end-to-end, their life cycle of trading – just like with securities – they can do the exact same thing with blockchain and cryptocurrencies."

The JSE is in no rush, however, and is taking its time to ensure that the launch is safe for investors, Street Forrest said.

"We have a steering committee that was designed and formulated to look at the Blockstation product, to look at the blockchain technology in general and to go through the phases to ensure that we understand what we are getting involved with and are also trained in what this entire trading of cryptocurrency involves," she explained.

As such, she said, the exchange's integration of blockchain will be "gradual."
