And also, any ideas or strategy/tricks/advices to maximize profits and minimise risks by playing this kind of gamble?
What do you mean by maximizing profits? The winning amount in a lottery with the same type as what you have shared is fixed.
And since it's a lottery, no strategy or tricks. Just hope for the best that luck will come to us.
Never saw a gambling site that offers a lottery the same as what you have shared with us. I will follow this thread.
