Actually since Dec 31st we allow up to 10% risk for any investor and JD now offers any risk level up to 99% as far as I'm aware.
The thread title and the stats posted are misleading and not representative of dice investment in general.
Some of the scam sites (on this list or not) were obvious or suspicious from the start and I and others tried to warn people of them.
But unfortunately people, including yourself, got scammed. It hurts the whole Bitcoin community, not just the gambling section of the forum and also makes it harder for all the legit Bitcoin operators.
The (total) ROI you posted isn't an accurate reflection of investing in the, very few, honest dice sites either.
Some of the investors at https://pocketrocketscasino.eu/ have over 100% ROI in the past 6 months and on average it is positive for all investors with a much better ROI than investing elsewhere. Even your own stats show 40% ROI which is a very good return.
Maybe you should keep the scam sites listed but show 2 figures for your ROI. One for your ROI from all the sites still in operation and one for the total like you have now?
