It's very interesting that your investment won't lose btc value if btc price goes parabolic, in contrast to any other enterprise you invest in: mining, sdice, etc, all of whom will shrink dramatically in btc value if the profits do not increase as quickly as the btc value.
Are you sure about that? I guess the value won't go down, but the returns will do. If BTC goes up massively then we can expect turnover to drop. You can always cash out though and get your original coins back (plus or minus whatever you won or lost).
The expected return of 6% per month means almost a doubling of your btc on a yearly basis. So you do get rewarded decently for taking the risk of trusting them to you.
I just ran some numbers now that I've got the bets in a database I can query more easily:

As you can see, the wagered-per-day is pretty up and down. Let's pessimistically say it's averaging 2.5k per day, with a 15k investment pool. That's an expected return of 0.17% per day, or 5% per month?
You also did a superb job in building your reputation. Great job indeed

Thanks, but I don't understand that part. I didn't really do anything other than argue about probability theory on here for a year, and accidentally find myself with almost 2k BTC on my hands when WBX went tits up. I didn't give it back to the WBX clients to "build my rep"; I gave it back because it wasn't mine...
