Well these are the kinds of people that will want to look for people to blame for their losses. I remember reading a reply in the first page that says "only if she shares her profits equally with me"..
that's a really hilarious suggestion but it's true. You only introduced her to it and never forced it on her so making such a statement just shows she's not ready. Just like every other investment that has its risks, Bitcoin is one of them or is this how she puts ultimatums on other investments.
Bro, I won't do anything if I were you because for starters, she won't invest with a huge amount seeing as she's so skeptical about the turnout and second, that statement she made is like forcing you to take responsibility for her decisions.
Over time we've come to understand that Bitcoin knowledge is not for everyone but that doesn't mean we won't do our parts by spreading the information even when there are people who prefer to stick with the idea that it's a scam project or a waste of money and time.
