Binance remains the largest crypto exchange by far , with a trading loudness of around $ 12 billion , as of reporting . The only other exchange to break $ 1 billion is Coinbase , but that commutation is alsofeeling the pressureof a world becoming more decisive of centralised crypto storehouses . What had been Binance ’s independent rival for some meter , FTX , recently go off and is already taking other major actors in the crypto blank down with it .
Binance itself has have other hacks this twelvemonth as well . In May , hackerstook 7,000 bitcoin worth around $ 40 millionat the prison term after they breached a wallet listed on Binance . In October , Binancesuffered a hackof its native BNB token worth somewhere between $ 100 to $ 110 million .

Celsius and Voyager are both give-up the ghost through messy bankruptcy proceedings , and of course there ’s FTX whose incredible implosion hasbrought down crypto lender BlockFi . Binance ’s own principal scheme officer Patrick Hillman toldCoinDeskon Thursday that their own centralize exchangemight not be around in 10 old age , as more of the crypto world may attempt to leave these exchanges behind for the greener pastures of the DeFi space . CZtook umbragewith the line that their commutation could be get in the next decade , but did n’t explicitly refuse it either . Of naturally , rent ’s not forget that decentralised finance go-ahead have been aprimary target for hacksthis year .
