Basically if bitcoin is too expensive, Ethereum will be the second choice of investment? Since its a strong coin.
Seeing that Ethereum always used to raise investment for many new projects, I can say that the demands always increase by the day. Every new project which use Ethereum smart contract will result in thousands of demands of ETH, and by that, I think that saying ETH is a strong coin is right.
Though, these fundraisings are just small part of ETH circulation, not an obvious reason to invest to ETH but just an additional reason.
