According to the recent SEC filing you all know, ETH is now a commodity - highlight: according to the SEC
Is there still a chance that some other force (e.g. congress) will overthrow SEC's right to make this decision?

Don't worry buddy, congress gave an opposite reaction for the ETH ETF approval. They are now thinking of finishing the crypto regulatory framework as soon as possible because the acceptance of crypto ETF means if public have been also accepting crypto to be a new commodity in our life.
The positive impact will be coming soon. I think cynthia lummis's tweet has been making everything clear. They are not working to the crypto regulations as soon as possible.
Just see the tweet has been published by cynthia.
