Could anyone tell me? why Bitcoin ETF is postponed?
Concerns over market manipulation -- at least that's
the answer provided by SEC chairman Jay Clayton. This is what he said earlier this year:
“What I’m concerned about at the moment is if it can be reasonably demonstrated that the underlying trading is generally not manipulated, it’s happening on reliable venues with good rules and that custody is something we can feel comfortable about.”
Presumably, they want to see global trading volume shift towards regulated jurisdictions and away from entities like Bitfinex, BitMEX, OKEX, etc.
