I guess that's from https://en.wikipedia.org/wiki/Dot-com_bubble ?

That's reported as a drop from the peak. But it doesn't necessarily reflect the real losses, in terms of initial investment. It's a number larger than the total amount of "real" M0 money in 2000, for example! Feels more like "an unrealized gain that never materialized" than "loss".

I remember that time, it was just after I graduated. There was a lot of business craziness on a scale that defi is yet to reach, although it's already hit some of my peak markers like "rename a stadium".

yeah, but the 7.7B is only the scam part - I'd suspect the bubble part of cryptocurrencies and NFTs will be much higher

So it seems like you are saying DotComs were a scam? Which is obviously insane. I believe we are seeing something similar in crypto. Yes to bubble, and yes there are scams, but wow it seems like there are a lot of people here that think the entire thing is a scam. There are a lot of insanely smart people working on this that are obviously not doing scams, maybe you should take a deeper look?
