No, this is not gender discrimination.
No, it really is.
I am only objectively speaking, because most female investors around me understand Crypto is difficult.
You're not being objective. You're being selective. Are the females around you the entire population of the world? No.
Including my sister, some of my female friends, although they also invested in Crypto, but until now they can not understand the Crypto / blockchain, this is a fact. We all have this experience. Why can't we admit this fact?
Maybe your sister is just an idiot? You ever thought about that? What happens if I have some black friends who don't understand crypto? Would it be fair for me to say that black people find crypto difficult to understand? No.
There are also a few girls who are better at crypto than boys, but this is not common.
This wasn't the argument. You said there are too many abstract concepts for women to understand and that they find knowledge more difficult. Maybe the women around you do, but I'm sure there are many abstract concepts you also don't understand.
The only thing you could factually say here are there are far more men involved in bitcoin than women, the rest is mostly just ignorance.
