since bitcoin was introduced to me few years ago i've got this thing in mind
is gambling really about luck or can you beat the house using maths and probability?
I guess not. House has the edge over the gamblers in online casinos since they are the ones that created the site. It's about luck for us to win more than what we lose during gambling games but overall, it's the house that winning over all the gamblers who bet on their site.
With my years in gambling, it really boils down to luck. And if you're lucky that day, it's better to exit otherwise, those probability will catch up on you and you will lose in the end. Discipline and self control is the key in gambling if you really wanted to "always" win every time you play.
