It's more likely a game of luck. Without luck, your strategy is nothing. Even though you have the best strategy in gambling, if you're really fortunage, you'll just ending up losing.
Disagreed with your opinion on ''without luck, your strategy is nothing'', have been in gambling over 3 to 5years now and have played with strategies and not luck. There is no luck in the world of gambling but a working strategy does. My last win on casino was 0.9
BTC which luck cannot give.
