Recently we witnessed the exit scam of @magicdice. There are many dice games still here. Do you think are they adding any value to the block chain or sucking the people's hard earned steem.
I say the mistake also lies with the people who using them to get quick steem. Like every scheme these games to built on algorithm to encourage you to invest more and more by giving profit on first initial amounts.
In the place of these we need real games on block chain which give entertainment with transparent rules and operation. People also invest their steem or steem power in wonderful projects like @qurator or @curie or @ocd for goo return on their steem if they don't have any other plans except investing in gambling.
Untill you leave your greed and start using your power and steem in right direction or giving it to right people you are adding no value to the block chain. This only effects us in long term.
