Too risky, risky to bet too big.
and too risky to lose a lot of money
This is very true and most cannot control themselves.
So imagine it was all in one wallet. You will lose it all or you will clean out the house, which would be cool ^^
Imagine the owners face

You will still lose in the end so if you really want money in gambling and you trust your luck too much then going all in is the best idea, with it being a method you can save your time and energy as you can easily determine the result.
