I believe they are innovations and better. Bitcoin is the myspace of cryptos but picking the facebook over the G plus is more difficult.

POS and ETH are likely to be disrupted too by the next best thing. This makes it possible / likely that their future value will decrease. Tbis fact makes investing less inviting.

We are already seeing what? Bitcoin didn't drop from 90% of the total market value until POS and ETH arrived, which are innovations, not clones.

I'll believe your paradox is valid when I see it--my hunch is that Bitcoin will be replaced atop the leaderboard by disruptive innovation.
