I was too young when the dotcom bubble happened, but from what I read on Wikipedia, the following were the reasons for the dotcom bubble and its eventual crash:

- Investors were eager to invest in any company with a ".com" suffix. Isn't this very similar to people just looking to invest in new ICOs (I still have no idea what those are)?

- There was a real sense of fear of missing out - investors just couldn't afford to not invest in a company because the entire market was investing in dotcom companies. Isn't this akin to how people invest in coins just because others are buying in? In fact, isn't the entire Bitcoin climate running on this?

- The market was confident that the companies would turn future profits. Isn't this too similar to "I'll cash out later when the exchange rate rises further"?

- An unprecedented amount of personal stock market investment occurred during the boom. Again, there are so many people blindly (not all, but some) buying coins without fully understanding the risk, purely based on speculation.

- Companies went public through IPOs so frequently. Now currencies offer an ICO so often.

Just reading through https://en.wikipedia.org/wiki/Dot-com_bubble#Bubble_growth I find so much similarity between the two scenarios.

I have heard some arguments denying a bubble - it mostly comes down to the statement that most new and brilliant things appear to go through a bubble. But isn't there too much of a similarity?

Again, I know this is a very beaten-to-death topic, so apologies if you're tired of hearing this (and I searched before asking HN).
