A cryptocurrency exchange, Bittrex has announced plans to block US-based users from trading in 32 cryptocurrencies after June 21. It said the users will be notified with an email with a detailed explanation. However, non-US customers will be able to access those markets that continue to be listed on Bittrex International, which is the cryptocurrency exchange ’s Europe-based affiliate.

Further, the concerned customers ‘may withdraw’ or continue to hold in their Bittrex wallet affected tokens and coins for as long as Bittrex International supports a market in those tokens and coins.

The blog post said certain markets will not be accessible to the US customers after the effective date. “US customers will have access to a more limited number of markets than are available to non-US customers on Bittrex International.” The cryptocurrency exchange features over 200 tokens and coins for non-US customers. It plans to add innovative blockchain projects to Bittrex International in the future.
