Coinbase halts Bitcoin Cash transactions.

Coinbase, one of the world’s most popular cryptocurrency apps, surprised its users by adding Bitcoin Cash to its offerings on Tuesday. But it appears that not everyone trading in the altcoin was blindsided by the move. Before the announcement, prices for Bitcoin Cash began climbing in other markets, and now a self-investigation of possible insider trading has been initiated.

Coinbase has launched an internal probe to identify whether its employees engaged in insider trading of Bitcoin Cash shortly before the cryptocurrency was officially introduced to the exchange yesterday. Increased trading led to a spike in Bitcoin Cash’s valuation, and just four hours after its introduction, Coinbase suspended trading of the digital currency.

According to the report, Coinbase is maintaining a strict trading policy and internal guidelines.
