在加密圈内，存在一类流传甚广，变种极多且历史悠久的加密欺诈——搬砖套利诈骗，欺诈者编写智能合约，声称只要存入ETH，即可超额返还其他代币，差价即为「套利收益」。但实际合约返还的是假代币，根本无法在交易所内兑换，受害者往往在损失两到三次后才发觉上当，但悔之已晚。
Within the encryption circle, there is a widespread pattern of highly variable and long-standing encryption frauds – brick-shifting frauds, smart contracts by fraudsters claiming that they can be returned over and above the ETH, the price of which is arbitrage. But the actual contract is returned in counterfeit currency, which cannot be exchanged in the exchange, and the victims often find out two or three times after the loss, but it is too late to repent.
自年初以来，币追Bitrace团队已收到超过100名受害者的求助。不法分子在某社交平台上冒充交易所客服，主动结识受害者，通过话术向其介绍一款“质押ETH，超额返还BNB”的理财产品，诱导受害人向欺诈合约进行汇款。有的受害者在早期的小额试探中，确实收到了真实BNB，由此加大力度试图循环套利，最终惨遭欺诈；有的受害者首次便大额投入资金，未尝甜头即被Rug。
Since the beginning of the year, the Bitrace team has received help from more than 100 victims. Unlawful elements have pretended to be exchange guests on a social platform, actively identified victims, verbally introduced them to an ETH pledge, overpaid BNB property, and induced victims to send money to fraudulent contracts.
受害者多以新手小白为主，这类受众对加密技术不甚了解，对欺诈骗局亦缺乏警觉，面对全套包装的假交易所客服更是毫无抵抗力。根据受害者提交的资料显示，由该骗局导致的受损金额大多在1ETH～120ETH之间，已经被报告的金额则超过2000ETH。
According to the information submitted by the victims, most of the damages caused by the scheme are between 1ETH-120ETH and more than 2000ETH has been reported.

币追Bitrace团队在对涉案货币进行链上路径分析后，发现欺诈者在得手后往往会快速进行资金清洗，隐藏资金去向。以其中一组高度关联的地址为例，清洗手法均为欺诈合约自动归集后转往囤币地址并拆分，最终辗转进入混币平台或中心化机构。
After a chain-to-trace analysis of the currency involved, the currency-to-bit team finds that fraudsters tend to launder money quickly and hide it. For example, a group of highly associated addresses are used to launder fraud contracts that are automatically returned to the money hoarding address and split, and eventually moved to a monetized platform or centralised agency.
而考虑到资金清洗手法、宣传话术、地址关联度的不同，我们意识到明显存在若干个不同的欺诈团伙在各自独立运作。可见该黑产已经逐渐产业化，这对广大加密货币采用者而言并不是一个好消息。
Given the differences in money-laundering techniques, propaganda, and address connections, we realize that there are clearly a number of different groups of fraudsters operating independently. So the black product has been industrialized, and this is not good news for a wide range of crypto-currency adopters.
针对不同的受众，这类骗局存在不同版本的变种，早前币追Bitrace团队就曾帮扶过「假HT搬砖套利诈骗」受害者。
2020年4月，浙江温州警方接到受害人报案。犯罪分子邀请受害人加入某“搬砖套利HT中文群社区”Telegram交流群，群内发布了一些“搬砖套利教程”并有许多群友分享按照教程操作确实获利的经验。其手法与假BNB搬砖套利欺诈一致，存入的ETH被兑换为毫无价值的假HT代币，造成了广泛的损失。
币追Bitrace团队根据链上资金数据帮助发掘了诸多受害者，并在案件侦查过程中提供了必要的技术支持，最终帮助受害人挽回了资产。
虚拟币诈骗常常包装为所谓的“搬砖套利”，“流动性挖矿”，“借贷”等看似人畜无害的高收益低风险理财产品，但背后往往暗藏猫腻，投资者有极大风险失去本金。
Virtual currency frauds are often packaged into so-called “brick-lifting arbitrage”, “mobility mining”, “lending” and other seemingly harmless, high-yielding, low-risk property items, but often hide behind them, with investors at great risk of losing their principal.
这类欺诈骗局存在已久，屡禁不止。根据币追Bitrace团队丰富的行业经验，我们总结出该类加密诈骗的以下几个特点：
Based on the extensive industry experience of the Bitrace team, the following features of this type of encryption fraud are summarized:
- 高收益低风险。以诱人的高回报率配合投资人贪小便宜的心理，达到诈骗的目的。
- 多次返利，徐徐引诱。犯罪分子为获得更大金额的款项，让受害人逐步建立信任，最终完成狩猎。
- 以优质标的为诱饵。本案中超额返利的BNB是知名头部交易所发布的代币，对受害者而言看似风险更低，也因此更容易交出信任。
正如加密金融领域内的一句名言——如果你参与了某个DeFi协议，却不知道收益从哪里来，那么你就是收益的提供者。
As in the financial domain of encryption, if you are involved in a DeFi agreement without knowing where the proceeds come from, then you are the provider of the proceeds.
链上欺诈活动的迭代演化正在加速，即使是同一类骗局，最新的引导话术与资金清洗手法都要比以往复杂。随着加密货币采用者的增长，更为广泛的损失已经不可避免，如果您不幸遭受损失，可以随时联系我们获取帮助。
The iterative evolution of fraud on the chain is accelerating, and even the same kind of fraud is more complex than ever before. As encryption currency adopters grow, wider losses are inevitable, and if you have an unfortunate loss, you can contact us at any time to get help.
