rational expectation
The inflow caused by ETF is expected to go much higher than the safe/rational expectation ... with a good chance for quite a bad crypto winter at the end of the cycle (but that's not in the current scope).
This being said, I expect to get to 1M one cycle earlier than what franky1 posted.
Still, we cannot know what the future holds. Imho we have to still stack sats and enjoy the ride.
The inflow following the ETF approval will surely continue to come but not as but not as massive as before. I am thinking that the ETF effect have already been felt. The recent market unwillingness to go beyond the $70,000 might just mean that is how far the ETF could take it. If that be the case, any other big rise in price is expected to be caused by the coming halving and not the ETF again. The time Bitcoin will reach $1m is very difficult to predict but eventually it will get there, maybe after several halving events and more important developments like the ETF.
