Well, I think bitcoin gambling sites as you referred to it as, or online crypto currency casinos, are neither a big opportunity for young people, but it's also not a big trap either.
Online crypto casinos is maybe somewhere in-between a big opportunity and big trap, and I say this because gambling generally is either good or bad, it all depends on our manner of approach; that is, our experience in gambling will solely depend on how we treat it, for example, you treat gambling like it's a business, this simply means that you will have to gamble every day and would depend on it for livelihood, something that all gamblers are highly discouraged from doing because this could destroy life and great destiny.

On the other hand, one could choose to treat gambling as a fun venture, play only with an amount of money he can easily afford to lose, this person would enjoy and have a good experience with it because he is gambling for the right reasons, people like this could one day get the opportunity of winning big from gambling, while other person who's livelihood depends on gambling, gambling may become a big trap for him because even though he potential of winning big is there, but he will still likely squander it all and lose the money back to the casino where the win came from.
