Very few would've been lucky to make a big winning out of gambling. I've earned good amount during the early days of my entry to cryptocurrency based gambling. By the time gambling looked to be a very easy thing for me, but for some reason it isn't the reality.
It is easy when you don't have to think of things that you're responsible for. And I think that's the reason when you're looking at gambling as an easy thing.
While you grow older from time to time, it's changing and you have other important things to manage than to put gambling into priority first.
It's the reality in life, time passing and you have to focus yourself to other important things in life.
Those time that you spent doing your gambling activities is not the same amount of time after some time, some might have a family to raise and instead of dealing with gambling they've chosen the other way to feed their family. For some, there's no longer enjoyment and they've realized that they are spending much time and money engaging with their gambling business.
