Pay me and I'll complete your survey.
How do you define "fully adopted" - you mean adopted, rather than adapted, right?
Is this measured by number of transactions, geographic spread of transactions, volume of BTC transacted, some declaration of another sort?
Also, will you be so kind to post the findings of your research here? We'd all benefit from reading it. And I don't think many people who come to us for polls bother to share their work with us, which leave us spending our valuable time for you but getting nothing in return.
