Is pump and dump illegal or not?
any form of market manipulation is considered illegal in any country as far as i know. and pump and dump is officially a form of "fraud" which is inflating prices through false and misleading positive statements, so that the manipulator can dump what he bought at a higher price.
if not can you share a link of it ?
