I am so tired of this women this, women that type of articles spouting gender gaps and highlighting stuff which ain't supposed to be highlighted. Technology, as far as I know is gender neutral. As to why there are more males than females doing blockchain, who knows? Women trying to do their thing and men trying to do theirs may be the only reason behind it. Let's stop over-analyzing things and move on to more worthwhile endeavors.
If all the virtual currency accepted country want's to bridge this gap or say want to encourage the women to participate in this so they could come up some more benefits for women investing in this virtual currency like some tax relief on the profits earned during the year.
