According to a report by Kaiko, the Bitcoin spot ETF in the United States has boosted global Bitcoin market trading depth, driven by US CEX. The share of US CEX in the 2% global market depth of Bitcoin has increased from 14.3% to 48%. On Tuesday, the total value of buy and sell orders within 2% of the market price on 33 CEXs rose to $539 million, reaching its highest level since October last year. Despite this, this figure is still below the $800 million level before FTX's crash.
