BI’s Article search uses Boolean search capabilities. If you are not familiar with these principles, here are some quick tips.

To search specifically for more than one word, put the search term in quotation marks. For example, “workers compensation”. This will limit your search to that combination of words.

To search for a combination of terms, use quotations and the & symbol. For example, “hurricane” & “loss”.

Coinbase ex-manager pleads not guilty to insider trading charges


(Reuters) — A former Coinbase Global Inc. product manager and his brother pleaded not guilty on Wednesday to wire fraud charges in what U.S. prosecutors called the first insider trading case involving cryptocurrency.

Ishan Wahi, 32, the former product manager, was arrested last month in Seattle on charges he shared confidential information with his brother Nikhil and their friend Sameer Ramani about forthcoming announcements of new digital assets that Coinbase would allow users to trade.

Nikhil Wahi also pleaded not guilty during an arraignment on Wednesday in Manhattan federal court before U.S. District Judge Loretta Preska. Mr. Ramani, who was also charged, is at large.

Prosecutors said Nikhil Wahi and Mr. Ramani used ethereum blockchain wallets to acquire the assets and traded at least 14 times before Coinbase announcements in June 2021 and April 2022. The announcements typically caused the assets to rise in value and generated at least $1.5 million in illicit gains, prosecutors said.

Coinbase is one of the world’s largest cryptocurrency exchanges.
