My girlfriend always starts the vacuum cleaner when I want to tell her about crypto.
I don't know why, but many many women just don't want to hear about it.
It's not that they would not understand it, they just don't want to hear.
It already occured to me that maybe it's genetic or so...
What did you say first to make her act that way? maybe she dont show interest because she thinks it is something that only men can enjoy. try to buy her a gift using btc or show her btc debit card that can be use for shopping then maybe she will get interested.
