There's a mistake on editing images or any deal like that? seems legit for 1.5x Payout get a double from wager

.
Yes you are right it is a mistake from our Editors.
Here's the real Bet information (Profit 1 BTC ofc, bet still valid):

I look at your High rollers and its rare these days to get someone to gamble >1 BTC. I remember back in 2015 or so there were tons of whales and they only gambled with multiple BTC. These days its only the alts that get bets taken with a whole number or greater.
Most people don't remember this but there was some crazy high roller guy who had an offensive nickname "f*ckit" and this was on Just Dice. I remember that he was betting something like 7000 BTC at some high odd like 98% or so and he took a roll and it was a loss.
This was probably sometime in 2013 or so. And it made news pretty much not only on Bitcointalk but pretty much on Reddit and many of the news sites.
What is funny is how he just says something like "oh well" and moves on with his life. Seems like no emotion at all. And these days when you are on the trollbox and someone goes bust by martingale complains about "Bitcoin and dice being a scam and everything".
Lots has changed in the last 5 years.
