>all savings of people who don't invest in cryptocurrencies are worthless, that fear may be driving a lot of the ICO speculation.

There are lots of ways to invest your money that aren't based on the dollar. Futures, real estate, company stocks, metals.

Sure, and they'll hold their value even in this scenario. But (other than the hedge funds) I suspect many people investing in these ICOs aren't big investors in those, and even among those that are, I doubt they'd like to see their checking account become worthless.
