Coinbase Is Largest Dollar Bitcoin Exchange
This note from Bloomberg may be of interest.
Read entire articleCoinbase is the largest market globally for trading Bitcoin in US dollars, according to multiple sources including CoinMarketCap, which may make it a market of significant size in the SEC's eyes. The largest Bitcoin trading markets are currently on Binance, but both are stablecoin pairs with Tether (USDT) and TrueUSD (TUSD). Coinbase's USD trading pair is third and at least 3x as large and liquid as No. 2 USD exchange Kraken. Coinbase also has multiple other Bitcoin pairs in the top 50, including USDT, EUR, ETH and GBP.
Combining the assumed Coinbase surveillance sharing agreement (SSA) with the regulated CME Bitcoin futures market might constitute oversight in an aggregate market of significant size. This is before adding potential other SSAs with spot exchanges such as Gemini.
