What if we bring in the theory of having parallel universes; for arguments sake, lets limit this to 1 additional universe, so we have 2 of them. And lets now assume this parallel universe is the inverse of the one we live in (or we think we live in, but that is a whole different debate). Would it not be that in the other universe, matter = dark matter and dark matter = matter? Sounds logical to me at least. When we are able to get into this parallel universe, we will also be able to see the force that may let every crypto dip as we speak. And when we can see it, we can do something about it.
