I guess it's all relative - you can do relative gap analysis, not based on financial performance but other fundamentals. i.e. If I know that Nebulas (NAS), a 3rd gen blockchain platform that aims to be the Google of blockchains with a search engine, eliminate hard forks, utilize lightning network, be dApp capable and introduce Proof of Devotion, is currently 300M market cap with an all-star leadership team, and other 3rd gen blockchain platforms like EOS, NEO and Cardano are 5-20B, you can bet I'll be putting my money there. [And yes, I'm shilling it, go buy it, it will 10x within a few months unless crypto crashes hard]
The difference between the beanie babies/tulips crazes and this one is that blockchain is truly a revolutionary technology and will up-end contemporary practices in a number of sectors. Marketing does matter and will make people a ton of money, but only until the real competitors come to play. See

I'd liken it more to the internet craze, where 1000s of companies sprang up, and only a few remained once the ashes cleared. There will be tech unicorns borne out of this. Question is which ones will be the next FAANG?
