Magic Dice amazingly simple game rewards users for playing dice, referring new users or delegating STEEM Power with MAGIC tokens. MAGIC token holders receive daily dividends from the profits that Magic Dice generates. I think @magicdice great investment as token distribution keeps halving at every day 0.25 %.
This is a real use case. The more people use the game more STEEM/SBD you earn. These are my earnings so far for 10359.4 MAGIC Tokens I HODL. These are payed daily. 
All you have to do is Login to the game with my referral link: https://magic-dice.com/?ref=keks and prove your identity with Keychain. I will upvote you 25% per each 25K tokens you acquire. All you need to tdo is go to and start playing.
