It could be argued that yes ETFs created additional demand but at the same time retail investors have been selling more than stacking.
It could also be argued that people buying via ETFs will be even more prone to selling on a bear market (because they are primarily motivated by NGU greed, than any principled stance) and so they are likely to drive any decline in price down more than OG hardcore stackers were in previous cycles.
I think the answer is NO. The fundamentals have changed permanently. The Bitcoin (and cryptocurrency) market will follow the US economic and stock market cycles.
