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 ..
Depends on the woman. Some men i know don't even really care about it. Perhaps do a search of some women celebrities that started accepting Btc. Next time you see that woman friend of yours, shove it in, in the middle of the conversation somewhere. "Oh, I wanted to tell you about Mel B and that she is using Btc now as well, which is crazy because I use it as well" blah blah ... "Seems this is getting more popular" .. The next time you see her, again somewhere in the middle of the conversation bring up how much Btc is worth right now, and that you found out the cost of sending "money" is super small, unlike banks which always overcharge. Just keep working it like that in a non intrusive manner and most of them will come around.
A year back when i started with Btc no one I knew cared about it at all. Right now, everyone I know, knows that I earn all income from Btc. They even know a bit about it, when it started, why it started etc. Persistence is key
