It looks like SafeDice was delisted. Any particular reason why?
Correct.
The problem with SafeDice is that support (on issues that only admin can handle) can be too slow. There are just too many times a post where someone is waiting for a reply for weeks for a missing deposit etc. I have been following that for a while and afaik the problem is always resolved. So IMO the admin is trustworthy and I personally still have my investments there. But owner really needs to improve support. If you are a gambler and having a problem, it is obviously a terrible experience if you have to wait many days/weeks for a reply. So that's why I temporarily removed SafeDice and I hope to see some kind of long-term improvement.
Note I do still follow stats at
