Some of the United States’ largest financial firms launched an exchange for digital assets this week.

Wall Street giants Fidelity Digital Assets, Charles Schwab, and the market-making behemoth Citadel Securities are behind EDX, a non-custodial crypto exchange. EDX will offer trading on BTC, ETH, and other major digital assets, according to a press release. Some investors say large financial firms have “bullied out participants so they can scoop up cheap coins.”
