Normally ETF keeps assets such as stocks, commodities, or bonds (in this case Bitcoin) and trades them.
We all are waiting for 11 March which is the deadline for SEC, they will either give ETF stamp of approval or disapprove it (again).
I have mistaken that "whaaat? 9th march" date as if asking of dump events incoming right before the deadline. To be honest I am totally exspecting the SEC to shutdown the ETF. Would be a major leg upwards, reaching into big capital markets. They will not allow that, you can smell bribes, hookers and blackmailing working in the backgrounds.
So my expectations for the 9th are: A dump will happen. But china doesn't have anything to do with that.
