Bitcoin battered: The worst crypto catastrophes of 2019


  Millions in cryptocurrency stolen, exit scams, and countless arrests were made in connection to crypto criminal schemes this year.


  The cryptocurrency market is booming, and with it, criminals are looking to cash in.


  Bitcoin (BTC) may not have sustained the $19,000+ price tag of previous years, now coming in at roughly $7,200 at the time of writing, but there is also a variety of other stable coins and altcoins, including Ethereum (ETH), Ripple (XRP), Monero (XMR), Bitcoin Cash (BCH), and Litecoin (LTC), that maintain a loyal following and constant trade.

  比特币(BTC)可能已经无法续写前几年1.9万美元以上市值的辉煌了,笔者在撰写本报告时,比特币目前的市值约为7200美元,但市场上除了比特币外还存在其他各种稳定的虚拟货币和阿尔特币,其中,包括 Ethereum (ETH), Ripple(XRP) , Monero (XMR), Bitcoin Cash(BCH), and Litecoin(LTC)等,这些币始终有忠实的追随者,关于这些币的交易也在不断进行。

  The industry has gained enough traction in recent years that regulators are beginning to shift towards the viewpoint that virtual coins should be considered taxable assets, with the IRS now hunting down cryptocurrency traders that do not declare their investments. The UK's Financial Conduct Authority (FCA) also clarified its stance (.PDF) this year on what coins can be considered securities or e-money -- some of which now land under the FCA's remit.


  Russia, too, known for its hostile approach to cryptocurrency, has begun to accept that cryptocurrency may have a legal position in the economy.


  With any form of asset that has financial worth, criminals will look for ways to fraudulently profit and cryptocurrency is no exception. The industry is rather unregulated, with laws potentially applied locally, but with exchanges registered worldwide, investment in cryptocurrency can be a risk.


  Exchanges are a common target. A weakness in a website, a vulnerability leading to exposure of a hot wallet -- storage systems used to hold virtual coins that are Internet-connected -- insider threats, and exit scams can all result in traders losing their cryptocurrency. Wallets, too, can be ransacked when vulnerabilities are found, and the blockchain itself, the backbone technology of cryptocurrency exchanges, may be subject to attacks . Unless cryptocurrency is stashed in a cold, hardware-based wallet that is not connected to the web, there may be a risk of cyberattack.


  Below, we take a look at some of the most noteworthy cases of hacking, criminal investigations, exit scams, and cryptocurrency-related breaches over 2019.



  Cryptopia: New Zealand's Cryptopia cryptocurrency exchange was pulled offline due to some form of hack, but details are scant. Trading was suspended and the firm went into liquidation.Estimates suggest that up to $16 million may have been lost.

  Bitgrail sentence: The previous owner of hacked exchange Bitgrail -- which lost $195 million in Nano coins -- was commanded by an Italian court to return as much in customer funds as possible, leading to the seizure of assets.

Suspicious API calls were detected and an investigation concluded the attacker(s) managed to access a database containing valid access tokens. It is still not known exactly just how many coins were stolen, but estimates suggest that at least $10 million was taken.

  Bitrue: Singaporean exchange Bitrue lost 9.3 million in XRP and 2.5 million in Cardano (ADA) from its hot wallet, worth millions of dollars. A hacker exploited a vulnerability in review process systems to steal customer funds.

  EtherDelta charge: A hacker best known for attacking TalkTalk was also indicted for an attack in 2017 on cryptocurrency exchange EtherDelta.

  Upbit: South Korean cryptocurrency exchange Upbit said that 342,000 in Ethereum (ETH) had been stolen from the firm's hot wallet, worth roughly $48.5 million. The exchange has promised that customers will not be impacted and the funds will be covered by Upbit assets.

If found guilty of breaking US law, he may face up to 20 years behind bars.

  Vertcoin: Vertcoin suffered a 51% attack in December 2018, and a year later, history repeated itself. This attack resulted in 603 blocks being removed from the VTC chain and replaced by 553 attacker blocks in order to perform double-spending.




  · 51%攻击,一种术语,代表着攻击者手中累积的算力已经超过加密货币网络中其他所有成员的总和,这意味着攻击者将能控制货币产出。

  · “双花”,又名“双重支付”,指的是同一个比特币同时进行了两次支付,这是一种利用区块确认时间差的欺诈行为。
