You seem confused. The odds are the same as they ever were. You've always had the chance to walk away with less than what you started with, in fact it's probable that you will, statistically speaking.
The odds have always been against you, and they still are. You know what house edge is right?
Of course I do, and I'm not confused but thanks for the offer. Hence my statement: "... (however so slight) that there’s a possibility that you could get it back...
But perhaps I could've been more clear. More or less I'm referring to the abyss of your deposit address on some of those 'scam' gambling sites.... you know the ones where your coins just seem to disappear even though you're playing 50/50 and about to lose 20 times in a row? Yeah, those sites
I'm just giving my observation/opinion that some reputable sites (those who actually allow a few to win every now and again), seem to be tightening up quite a bit. Does that make better sense?
No, because they are provably fair. If you think they are rigging bets there are things you can do to make it impossible for them to do so in the dark. Of course they can always steal from you once, but at least you'd have proof of it. Of all the accusations I've seen, I've only heard "20 in a row!!!" (statistically possible) and the like over and over again. I've never seen hard proof, as in fixed rolls with all the seeds.
If you don't use those checks and balances to be sure you aren't being had, well that's on you. The table has always been against you loosing though, you've never had the chance, no matter how slight, of coming out ahead after many bets. Placing more bets just gives variance more of a chance to screw you, as it is supposed to.
I don't play betting sites, but I know how they work.
I am so mad 
At least it wasn't a really substantial amount, classic case of how you should always read the fine print and the hidden stuff.
