What if: the $BTC ETF turns out to be the greatest pump & dump of all time?

I'm not FOMO-ing into this one because all my spare money goes to $AMC - but, I have a few coins that I use "for reasons" so I have one eye interested in the movement of bitcoin this week.

Lots of rumours around the ETF and a new ticker being listed ($IBTC) and notes underneath saying how this pretty much guarantees that it will happen.... Pending approval from SEC.

So BlackRock pump the hell out of bitcoin on speculation of SEC ETF approval, then whoopsie SEC don't approve it because of the implications of damage to USD or something along these lines. If this happens the news will come the day after a suspiciously large sell off i.e. Kenny and BlackRock getting out before you do = liquidity. $Coinbase(COIN.US)$ $Proshares Short Dow30(DOG.US)$ $S&P 500 Index(.SPX.US)$
