The Telegram bot (which is really awesome, by the way), is showing that it was redeemed for 267.999 BTC.  It seems to be double counting the change amounts after the test transactions.  So when they spent the first 1 BTC, there was 98.999 returned as change.  They sent another 30, leaving 68.999 as change.  So the bot added 100+98.99+68.99 = 267.999 or ~$16 million in value. 

I think I have noticed this on a few other alerts. At first I thought they were overfunded coins by the end user.
