B2BX is an aggregator of cryptocurrency liquidity for marginal trading, trading with physical delivery and distribution of liquidity to brokerage companies. We are planning to make the first official B2B cryptocurrency exchange-aggregator or marketplace, in which we will connect at least 5% of the market of Forex/DMA and Stock brokers, and give them the opportunity to provide their clients with the trading in cryptocurrencies. While the current solutions in the market are focused on retail, B2BX will focus exclusively on institutional clients: stock and crypto-exchanges, Forex and DMA brokers, cryptocurrency brokers and exchangers, hedge funds and other professional market participants. All participants will be controlled by the exchange and financial regulators. B2BX will provide a rating of brokers and will act as a guarantor of reliability for customers who will choose as a broker member of B2BX. Thus, B2BX will give advantages to both: financial institutions and retail customers. In particular, B2B customers will be provided with a depth of market for cryptocurrencies due to the fact that B2BX will unite brokers, exchanges and other financial institutions on one platform. In the same time, retail customers will have the opportunity to trade cryptocurrencies from any usual broker, stock exchange and exchanger.
