how we could motivate women to use Bitcoin because I tried several times to explain what it is and how to use Bitcoin ...was very difficult and have not really managed only once ..
If you talk about mining, technology, ASIC, .. they'll surely get bored.
You have 2 chances:
* start with... colored coins!

joking, there is only one chance:
* give them a good amount - at least 5
BTC and tell it's real money with
real value. And show how it can be
spent. Now they have your attention and you can give some technical from time to time, but not too much.
