I hoped to have played these slots with micro bets too... but they are just a BTC to $ conversion of the original Fiat casinos... not really Crypto games. 
This is a con that I have noticed too. One of the best parts of crypto gambling is the ability to bet with minute amounts so that we can stay in the game longer and have more fun. 3rd party providers should have done better in this aspect.Bad experience when I played DICE, all my funds disappeared with successive defeats, this is my sad day, is there any advice in the game DICE? or is there a good strategy in playing DICE here?
There is no perfect strategy for any game in gambling. If you wish to have fun, you could try strategies like Martingale, D'ALEMBERT etc, but don't expect to always win or anything.
