Should've known what exactly? Cryptocurrencies are a huge success as a speculative asset but beyond that I see a lot of whitepapers and marketing pamphlets but very few actual results. I suspect the average speculator doesn't even use the technology themselves, instead keeping their coins on a centralized exchange for safety and convenience. When's the last time you've actually used a Blockchain? What is there even to use in the wild today? There are a few Dapps PoCs that rely on 3rd party cloud storage services like Azure because storing data on-chain is too expensive, have a rather dubious business model and probably fewer actual users than lycos.com. Given the amount of money poured into cryptocurrencies these past years I'm not impressed, if anything every passing day without a Blockchain killer app reinforces my belief that it's mostly wind.
