:) These games arn't new, Eos did it firstly and then Tron, now Steem... just 4 months later than eos and tron dapps..

There is a term known as "mining" with these gambling dapps, which means that anyone can set it to a 95% chance of winning, and then "mine" the dapp's tokens with a minimal loss, and thus can be seen as an investment because after all you are owning shares in the gambling site which will be paying you dividends.

For example, I managed to get 2.3 million MAGIC, and it cost me pritty much nothing at all, but now the bonus rate has changed dramatically since I did it.

I'm not into gambling, I'm into investing in the crypto world, and when our DEX is up we shall see many copy's of MagicDice, and also new tokens, new mining and mining stages, etc etc.. History repeats itself.. :)
