Nothing will come of it, because...
Bitcoin Price Drop From $20,000 Likely Due to Market Manipulation:
When 'purchasing and selling' is 'market manipulation' the fundamental principles of the Free Market are in question. Should people not be permitted to buy and sell whenever and however much they want, for whatever price is mutually agreed? This is more than just a few disgruntled bitcoiners upset at not getting their expected return, it's actually an attack on freedom, democracy, and even Capitalism itself.
Bitcoin was invented so people could trade freely without being limited by corrupt banking practices and unnecessary regulation. It cannot be manipulated by 'flooding the market with fake orders to trick other traders into buying or selling' because every transaction is recorded in the Blockchain for all to see. No matter how much the price varies or what the cause, nobody can complain that they didn't have access to accurate information.
Bitcoin doesn't need to be investigated. If the price crashes that's just market forces in action, and anybody who can't stand the heat should
get out of the kitchen.
