Yes there are so many methods for playing safe in gambling, for example when you bet 0.04bitcoin into a dice game and won(1.90x) why not quit while you have the given money. That is already a huge sum of money if you convert it to FIAT. Then come back for tomorrow to play again to avoid to avoid unnecessary outcome if you continue to roll. Use your head when you are playing over your emotion, when your emotion controls you while you are losing better to cool off. Quit for a while then continue if you are on your mind.
But with your analysis what if I lose at the first attempt will I then be safe? Because it is gambling and the chances of winning might not even occur in the first four attempts by that what do I do? The fact is there is no safe way to gambling the only available means after some understanding is just to reduce the way losses will occur thereby increase chance of winning...
Yeah this is quite risky if you will bet high amount in dice as we know the chances of winning in dice game are even lower for the house edge has always the favor. But if you think that you are the luckiest guy in the world then you may try this tip out but don't blame someone if you will lose for that amount is not even a joke.
