Binance is addressing a loophole in its Link Program that allowed prime brokerages to exploit its multi-tiered fee structure for arbitrage purposes. The exchange is tightening rules after some partners reportedly took advantage of discounts on trading fees by grouping accounts together or trading on behalf of clients, which led to additional revenues. This move is part of Binance's broader effort to curb misuse and ensure compliance across its platform amidst ongoing regulatory challenges in various jurisdictions, including fines and operational restrictions.
