June 21 (Cointime) - Binance.US, the US arm of the global crypto exchange, is facing criticism from regulators and has been struggling to maintain some of its largest bitcoin order books. On Tuesday evening, the platform displayed the price of bitcoin at over $138,000 for its tether market, almost 400% higher than spot prices elsewhere.

This sudden surge only lasted a few seconds, but during that time, 62.22 BTC changed hands, equal to about $1.8 million at current prices. Binance.US has been experiencing liquidity problems for some time, which have been attributed to regulatory issues and banking partner struggles.
