I call bullshit on this. Their number very likely includes the change that gets sent back. So if you have 1 BTC on your wallet, and you make a payment of 0.01 BTC to buy groceries, you send 0.01 BTC to the merchant and 0.99 to a change address, this likely gets counted as 1 BTC being transfered.https://toshitimes.com/bitcoins-daily-transfer-volume-close-to-overtaking-mastercards/
EDIT: Also applies for just sending BTC from one of your wallets to another of your wallets.
