比特币交易所Coinbase在两天内遭遇两起联邦集体诉讼，其中一起诉讼指控员工进行比特币现金（BCH）内幕交易。

在3月1日提起的第一宗诉讼中，原告声称Coinbase员工通过内幕信息交易非法获利，该交易所计划在2017年12月推出比特币现金支持。

这一诉讼由首席原告杰弗里·伯克代表自己和一批Coinbase客户向美国加州北区地方**提起。

人为抬高价格

该诉讼指控，Coinbase员工的内幕交易活动人为抬高了比特币现金的价格，导致客户和加密货币市场的其他人（他们没有内幕信息的好处）在他们的交易中不公平地赔钱。

原告在诉状中称：

On December 19, 2017, a month after tipping off its own employees as to when it would commence fully supporting BCH, Coinbase suddenly announced that it was opening up its books to the buying and selling of BCH within minutes after its announcements. Unsurprisingly, those who had been tipped off, immediately swamped Coinbase and the GDAX with buy and sell orders, thinning the liquidity but obtaining BCH at fair prices. The market effect was to unfairly drive up the price of BCH for non-insider traders once BCH came on line on the Coinbase exchange.

事实上，比特币现金的价格和交易量在12月20日大幅飙升，如下图所示：

该诉讼要求陪审团对“在2017年12月19日至2017年12月21日（含）期间向Coinbase下购买、销售或交易订单的所有Coinbase客户进行审判并支付未指明的金钱赔偿金。。。以及因被告的不当行为而蒙受金钱损失的人。”

被指控有不公平的商业行为

第二起诉讼在一天后提起，Coinbase指控其“非法和不公平的商业行为”，并违反了加州无人认领财产法。

蒂莫西G。Faasse和Jeffrey Hansen在3月2日代表一类客户提交了一份文件，指控Coinbase欺诈性地保留他们知道不属于他们的资金，仅仅是因为用户没有认领。申诉称：

Imagine writing a cashier’s check to a friend. The bank withdraws funds from your account, but your friend never cashes the check. Does the bank get to keep the funds? The law clearly says no. But this is exactly what has happened with Cryptocurrencies sent through Coinbase.com, owned and operated by Coinbase, Inc.  Coinbase users can send Bitcoin, Ethereum, Litecoin and Bitcoin Cash (collectively “Cryptocurrencies”) to an email address. Plaintiffs and the Class were sent an email from Coinbase stating they had Cryptocurrency, with a link to create a Coinbase account to redeem it. But until 2017, most people never heard of a “bitcoin” or cryptocurrency, so most of these emails were disregarded. And most of the Cryptocurrency went unclaimed. But instead of notifying Plaintiffs and the Class they had unclaimed Cryptocurrencies, or turning those Cryptocurrencies over to the State of California as required by California’s Unclaimed Property Law...Coinbase kept them. 

irs获取coinbase用户数据

Coinbase的这几周很艰难。今年2月中旬，这家数字货币兑换和钱包平台被指向客户多收费。

在用户的愤怒之下，支付处理机构Visa公司（V）后来承认，它对收费错误负有责任(更多信息：Visa:Coinbase不对向客户多收费负责。）

一周后，Coinbase通知用户，美国国税局已下令它交出13000名客户的数据。为什么？因为山姆大叔想对你的比特币收益征税(更多信息：美国国税局想对你的比特币收益征税：命令Coinbase交出用户数据。）
