Can you explain how someone that owns an altcoin is manipulating it? If they only have the altcoin then all they can do is sell. Its not like they can manipulate the price upwards unless they have additional assets. For some market participants they have multiple pools of capital. But the mere existence of consolidated ownership doesn't mean its manipulated because that alone doesn't make sense? Curious if you could articulate the process you imagined. I've seen your version of events mentioned alot on twitter, discord, telegram and similar threads, but its just like the reductive "must be money laundering" comment also often seen, how does that work exactly?
