When was this picture taken? I assume this week? If so, that is very damning and puts a nail the coffin.
Every morning I copy/paste stats from a few dice sites for my records.
Here are my last two entries for dice.ninja:

So the screenshot was taken after 7:42 am today - after Finn made his video - because it shows more than 970k BTC bets.
Edit: but the chat itself is a couple of days old. There's not much chat activity at dice.ninja, so old chat hangs around for days.
