This is a pure scam. Selling their large number of tokens, which would result in a decline in the price and eventually cause panic among investors, is something that can't be done if the owners believe in the future of the project. That's the risk, though, as we can't deny it happens with some projects. However, considering the reputation of TrustDice, which has been in the forum for a while now, I think they won't do that. But I agree with what you posted: manage the risk.
Probably i can invest but like a HYIP - with fast withdraw deposit, but i need at least 5% daily for it, better 10%. After it it would be interesting for me to invest in well-known cryptocurrency casino.
