I'll tell you more, even over $ 700 for a bitcoin to buy it is very risky. It may go down even lower. And if you start a third world war, then he can do to stop demand.
It's quite funny when I see nonsensical comments like this. If you are worried about risk of owning bitcoin, then why do you even here?
Bitcoin was always explosively volatile, this 'feature' is not gonna change anytime soon.
And stop please use war as argument against bitcoin - it is basically argument against fiat, stocks, securities and every kind of financial instrument.
