Bittrex used to be a much larger presence in the US, enjoying more than 20% of US market share in 2018. It has since dropped to below 1%.
The entity that filed for bankruptcy in the US is Bittrex, Inc., which is separate from Bittrex Global. "This announcement does not impact Bittrex Global, which will continue operations as normal for its customers outside the U.S.," said a Bittrex spokesperson.
