Is there anything legally wrong with manipulating crypto courses? Or even ethically? The supposed main advantage of cryptos is that they are independent of governments and institutions, and their rules. And in this case, that's exactly what they get. And besides that, without 'manipulation' (which I'd say includes any kind of marketing), cryptos would inherently be worth exactly nothing.
