Crypto exchange Bittrex, which filed for bankruptcy in May, may remain profitable as customers do not withdraw their funds. Between the filing of the claim and the deadline for filing claims, fewer than 36,000 customers withdrew approximately $143 million in cryptocurrency. In total, letters were sent to 1.6 million clients with an offer to withdraw funds. One of the largest accounts belonged to the US Secret Service Agency, which took $6.2 million.
