I doubt it. Apparently Congress showed more interest in hearing the guy called DeepF_Value (the reddit poster who started it all) rather than shedding light on the shit that went on between RobinHood and one or more clearing houses.
He wasn't even one of the earliest guys to buy in. He got in 2019 or so. Some other guy has been holding GME since 2017 (but did end up selling above $300 or $420 I believe, he said).
As for ETFs, following Grayscale or QBTC (3iQ Corp), no fund in their right mind would launch without holding either 100% or more of the underlying (which is BTC.) By more, I would say they could have 99% and some extra cash, but probably hold 120% in BTC and only issue 100% of the shares or something like that. In any case they can copy the existing funds and what they're doing.
