I tried to convince many women but they were simply not interested in bitcoin, they said they have credit cards and physical cash then why to waste time in bitcoin.
That's the main problem that we have to provide the solution. Indeed most women always think the easiest thing and not too ribet. A lot of women who just want to easily without looking at a much bigger profit. But I'm sure if we provide information that is complete and detailed as possible there is still hope for them using bitcoin
I don't think most of them will not be interested. Maybe you are doing it the wrong way. Maybe you are forcing them to use bitcoin instead of motivating them LoL
and this is a different kind of motivation

Step 1. Make a website called "bitcock" (as the name implies, takes bitcoin for cock delivery nationwide)
Step 2. Advertise on facebook, in-person, etc
Step 3.

Somehow you can get horny women to be motivated by this kind of stuff but, you will lose those decent one.
Why not try to treat them as ordinary people. Just teach them the basic and guide them as they grow. There maybe some reward if they progress but well people are drive motivated by reward.
