Actually there are already articles appearing the G20 will not be looking to crack down on cryptos as much as had been feared. Some sites are even attributing Bitcoins bounce to the news, so I think if this dip was the result of those fears it is near bottoming.
I do think there is more than just the G20 meeting factoring into all this, so while we may still have some rough waters ahead, I don't think it is going to nose dive to $3k or anything.
