Binance has long been the world’s largest cryptocurrency exchange by trading volume. Still, on Monday, traders looking to buy and sell bitcoin (BTC) quickly on Binance were at a relative disadvantage to their peers on Kraken and Coinbase (COIN), according to data tracked by Paris-based Kaiko. The 0.1% ask depth on Binance, a measure of buy-side liquidity, crashed to just 1.2 BTC ($30,000) from 100 BTC as volatility exploded after an erroneous report that BlackRock’s (BLK) spot exchange-traded fund (ETF) had been approved circulated on social media. The leading cryptocurrency popped 7.5% to $30,000 in a knee-jerk reaction to the rumor, only to give up gains after BlackRock denied the report.
