Just like in trading and other aspects, it all depends on your luck to win something as big as a jackpot, because in most cases the regular thing to do is to just stake an amount you can afford to lose and never expect too much from the games at any point in time regardless of your previous experience if winning..
We can't actually classified trading to be a luck based of a thing but instead knowledge and skills, you know when someone goes for knowledgeable it becomes more easier for the person to succeed in trading and when the necessary research are being made upon it also create more chances and likelihood to excel while trading. But however, only some coin that we would say that depends on luck where if you are lucky enough and the coin pump to an extent we can say that person is lucky and can easily sell to make profit.
