I think that people will want to secure a passive income. They will slowly start buying Ethereum until they have 32 Ethers. After that Ethereum will be bought only for paying fees on this network, not as an investment, so consider it.
I think way too much is made of this idea of passive income. What good is a 5% (or whatever amount they come up with) reward in something so volatile? I mean, look at coins like Dash and others... 5%+ reward is fine if a price is stable or rising, but in an investment that can lose 90% of its value? I mean, why bother? If someone wants 5% interest, just put the money into some junk bonds, which are considered risky as far as bonds go, but are a zillion times safer than any crypto. Or put the money into stocks, or real estate, or lots of other things.
Not that I think ETH may not get a pump from 2.0, it just seems weird to me to think passive income would be the reason.
