This for me, is a very shallow reasoning you have just given here. Playing around and not being serious with life isn't gender-related at all, anybody can choose not to take his or her life seriously and so I think it should never be considered in the first place.
A little surprised when you who created this topic actually consider other people's responses as very shallow reasons, so I need to know the deepest reasons you have for this. Because I don't think that people who have been successful in this world live in a way that is not serious, but on the contrary, they always work hard to be successful and this is clearly not limited by gender. And if you think the reason I have limited this to gender, it seems you need to re-understand what I said previously here.
On your second point, people don't necessarily have to tell women about Bitcoin before they know what it is, as a matter of fact, the majority of those women who are not directly into Bitcoin or tech already know about it but for reasons best known to them, they decided not to venture into that field.
If you consider the second point to be important, what is your aim in creating this topic? Someone who doesn't know about Bitcoin certainly has nothing to tell his own woman, but does that also apply to those who already know Bitcoin? It seems that you prefer to think in one direction without changing direction into two sides in this case. Each person's life journey is different and each person's response to anything is different, so you cannot equate your thoughts with other people's thoughts in matters like this. Because telling a female partner about Bitcoin is very common even if the woman does not make further inquiries into what she has heard from her partner.
