In the past 12 months, this figure has been between 1.3% and 3.1%. Binance is discussing a proposal to allow some institutional clients to deposit trading collateral in banks rather than cryptocurrency platforms, a move that could help reduce counterparty risk. People familiar with the matter said Binance has discussed a setup with some professional clients that would allow them to use bank deposits as collateral for spot and derivatives margin trading. Switzerland-based FlowBank and Liechtenstein-based Frick Bank are considered potential intermediaries for this service.
