the proliferation of ICOs being caused by Ethereum is not going to siphon more value out of ETH than into it.
If most of the fools who still believe in the viability of smart contracts on a Turing-complete scripting blockchain are still invested in ETH and they are the ones who will trust these ICOs built on these insecure smart contracts which are another
