Not sure what you're trying to say.
Sure the ETFs will find their ways to get to BTC. The rule is that they have to settle by the end of the day, as far as I know. That seems to be part of the rules.
Essentially I think we are at the start of a bullrun, the normal 4 year cycle.
Somehow I do believe Alts will behave differently this cycle. I do think Alts will lift itself with BTC lifting itself. Coming weeks/month(s) perhaps BTC is going down a bit further, but I see this more as sideways action with a relatively large amplitude.
Retail will always be rekt. I mean, the retail that isn't active yet, those that aren't too familiar with the dynamics of crypto, those who chase runups and go in/out all the time. Those who think they can make themselves rich quickly. Those who aren't too interested in investing. Those who don't have the patience and run when a token goes down 20/30%.
