data obtained from CoinMarketCap, the combined 24-hour trading of all cryptocurrencies rose up to $11.5 billion shortly after 16:00 UTC. The only time daily trading volume has surpassed $10 billion was on August 19, when it briefly spiked to $10.5 billion.
Bitcoin topped the charts with $4.2 billion, while ethereum and litecoin posted $1.9 billion and $1.5 billion, respectively. In all, 10 different currencies posted greater than $100 million.
Bithumb and Bitfinex each handled about $1.5 billion, while Chinese bitcoin exchange OKCoin accounted for $750 million. Altogether, at least seven exchanges, including GDAX, Bittrex, Poloniex, and Huobi surpassed the $500 million mark (Volume had tapered off a bit by the time of writing, so it is possible Kraken and Coinone crossed $500 million earlier in the day).
