We look at a recent report from Protos that traces the issuance of USDT to the institutional players in the centralized crypto capital markets. The data reveals the market share of players like Alameda, Cumberland, Jump, and others in powering trading in exchanges. We try to contextualize this market structure with what exists both in (1) investment banking and (2) decentralized finance. The analogies are helpful to de-sensationalize the information and calculate some rough economics.
