Alt coin season theories

In previous cycles, bitcoin has gone on a run following the halving and once this starts to plateau capital starts moving into alts and alt season comes to life. I'm wondering with the new ETF money being concentrated in bitcoin (and not able to move into alts) whether we are likely to see the same pattern this time around. The ongoing ETF injection from pension funds etc and the increased adoption form others that this will bring will result in greater ongoing upward pressure than we've seen previously and the plateau may be a long way away. But there will also be people always chasing moonshots and wanting to use some of their bitcoin gains to achieve this.

What are everyone's theories on how alt season may play out?
