We have to educate them (women) that bitcoin is the same as fiat money in digital form.Guide them to open a bitcoin wallet and gift them some bitcoin to try online.Once they are comfortable with system,they can use it anytime to transact online online to pay their bills,shopping etc.
i think in this momenth we can found some woman interesting to join and earning bitcoin, also i see some woman comuntity support bitcoin, like bitcoinwoman, bitcoingirl(youtube) etc.
in future im sure more woman use bitcoin.
