I couldn't agree more, I've had similar thoughts as the total market cap reached ATHs.

If it's too early to invest in the tech and/or if most projects are overvalued/junk, what are your expectations for Institutional money in 2018?

I imagine most institutional money being attracted to blockchain tech that embraces compliance, transparency, and a certain degree of centralization (Ripple seems to fit the bill best here).

Or, perhaps a more decentralized platform whose tech can prove to be an order of magnitude better than what's currently available (DASH/BCH/EOS) and that can safely support the needs of business on the blockchain, part of this is solving for the scaling problems that seems to plague most platforms as they become widely adopted.
