The advertised house edge for the Stake in-house Black Jack is 0,5%, which means longterm I will lose 0,5% of all bets placed.
That's incorrect.
That is 100% correct!
I will statistically lose 0,5% of every bet amount placed and practically I will lose 1 bet every 201 bets placed, because 200 x 0,5% = 100% = 1 bet.
You have a fundamental misunderstanding of what House Edge means.

House Edge has nothing to do with percentage of winning vs. losing hands --
Correct!
But the clownfish AHOYBRAUSE quoted the percentages of winning and losing a Black Jack hand!
Correct!
Like I always say, when the house edge is 0,5%, thrn statistically 0,5% of each bet amount goes to the casino.
Practically, every 201 bets, 1 bet goes to the casino.
Oh, I see this was addressed in the 2nd post:
What has house edge to do with expected losses in a win/lose ratio??
House edge will be accounted for wins and losses profit wise, not for the game outcome :: .
I can see only nonsense claims!
"What has house edge to do with expected losses in a win/lose ratio??"
What is a win/loss ratio?

"House edge will be accounted for wins and losses profit wise, not for the game outcome"
What are wins and losses profit wise

What is the game outcome

Nobody is going to take this thread seriously. Not sure how it continued on this long.
It continued that long, because sickheads have hallucinations and then publicly false and misleading declare their hallicunations as facts!
