Let me clarify what I mean by saturated. The BTC wagered over the past 4 weeks is very small compared to such a large bankroll. So site profit (even taking into account one bad run) is pretty diluted from an investor perspective. Low volume + big bankroll = small profits. I'm not saying any of this is bad. I just wanted to put some context to tarantoga's comments that "investments are returning" and citing a big bankroll as evidence.
Yeah, I appreciate the sentiment, and my own calculations of annualised return from the site are now moving down, though before the big downtime a few weeks ago, the bankroll was 10% larger than it is now and there was no saturation.
Thus, BTC wagering has dramatically declined. I'm not quite sure why that is. Maybe it was one downtime too much. But I think it's about time the signature campaign got underway to bring SD back to normality.
EDIT: I might see what you're saying actually; investments are returning, but they are not generating any return!
