Smart people moving into cryptocurrency and cryptocurrency being a bubble aren't mutually exclusive in another way: the long term potential of cryptocurrencies

Smart people moving into cryptocurrency and cryptocurrency being a bubble aren't mutually exclusive in another way: the long term potential of cryptocurrencies could be valid, even if it's in a short term bubble. I think there are a lot of parallels between cryptocurrency/block chain tech now and the dot com bubble in the 90s. During the dot com bubbles fortunes were made and lost over nothing and there were many scams and vaporware business, but the underlying tech was sound and if you could identify the real businesses (e.g. Amazon, eBay) from the trash you could still make a lot of money in the long term even as the bubble popped and the market crashed. In a way, the bubble popping was good in a 'creative destruction' sort of way for clearing the brush (scammy and terrible companies) so the real ones could emerge and thrive. I think something similar will happen with cryptocurrency and blockchain tech.
