All promos and giveaways are effectively a reduction in house edge. We prefer to do it this way because it's easier for most people to understand.
I get that, thanks for the response TQ! A bit of wishful thinking I know and a bitch to code, but I'd switch off RP and lottery gains and maybe even Golden Ticket gains if I could see an immediate switch in house edge on wager (then people don't need to understand it, they'll see the immediate change in chance to win with each option toggled off.
For those wanting an update of the win...
I went with the BTC option. Over the next week I lost it all back to the site.
That feel when you wish you could go back in time two weeks for just one do-over!
I've been there before, but on a whole lot less than 20+ btc! How'd you get most of your GTs? Wagering mostly I guess? Then at least the silver lining is no money out of pocket.
