Seems to me mostly a (valid) criticism of ICOs, which are kind of like penny-stock. No one would put all their money in a single penny stock, right? It doesn't say much about buying stock in companies who have 'blockchain' in their name. Many of these seem like traditional startups (and many will fail), but can any of them provide fast growth? if not, any long term value? Disclaimer: outsider point of view, I know nothing about this. I stopped using Bitcoin when renewing a domain name would cost me $5 in fees for a $15 transaction.
