Does anyone whether this will be public information immediately? I mean, it really is quite simple to take advantage of such knowledge in advance in the Bitcoin market and I doubt there exist any laws against it.
If/When the ETF is approved within 2 hours of approval it will be on the major media sites.
After that it will be 2-6 weeks before its released on the Nasdaq for purchasing, this will give people time to anticipate it. Some already are ready for it.
2 hours is too much, by that time the value would have increased by 100%... I'd want to know the news after 1 second.
