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.
Crypto should go higher. So few people are smart enough to actually trade the market on fundementals, they're still reeling over what digital decentralized money means for the future... I expect more interest in crypto in 2018 and people investing into it more.
I now know several every-day people who now want to invest into crypto now that's gone up. Millionaires and billionaires are thinking likewise, the sector will see more money into it. And there is a decent reason for investing into it now, because some projects do have valid and compelling use cases, so they are actually worth something long-run. BTC should keep going higher in 2018, I believe. The rest of crypto will follow, the good, bad and ugly.
