common sense says its a scam.
Absolutely no information provided on their sites (I've even read that picture were stolen and fake profiles were created).
They refuse to answer simple questions regarding their project and prefer to block those questioning instead of simple answering their questions.
All media related to Idice are paid advertisements. NOT ONE IS ORIGINAL!
They claimed dividends would be paid when reaching 500 ETH. Passed that a couple of days ago, still no payments!
Such a pity though, great potential project in the hand of total loosers. Cant even define such despicable characters.
