Long term gambling is equals to more looses but if your lucky enough maybe it can lead to more winnings. gambling is still a gambling even though you play for a long term or in a short term both of them has still the risk and benefits that you may get is only a small percent or chance because usually most of the gambling are mainly depends on luck and not on skill or any superstitious beleifs. Same as in long term trading and investing.
No mate, Trading and investing is not same with gambling in terms of results, you can manage to keep doing well with investment and trading if
you will find way to enhance your knowledge, better to separate this thinking, gambling in long term period will just lead you to be more greedy,
as we seen that only luck will let us win and nothing else, you can find enjoyment in a short period of time but a lots of stress if you will stay for
a much longer period.
