These last days I checked coinmarket cap (https://coinmarketcap.com/currencies/bitcoin/) several times to check the volume traded in the last 24 hours. I know that this value is a hard thing to measure due to wash trading.

So during these last days, the volume traded in 24 hours is usually between 30 billion and 36 billion USD.

In the last 24 hours, accordingly to coinmarketcap, it was traded more than 102 billion USD in bitcoin markets.
