Crypto has had at least 3 distinct bubbles. There's the current one, marked by Eth's absurd rise to $300. The previous one was when Bitcoin made an absurd rise to $1200 in 2014. There was a bubble before that where Bitcoin rose to $266 in 2011. And one before that I believe where Bitcoin rose to $32 in 2010.
Though crypto has risen past the high point of each of these bubbles, each price point can be definitively classified as a bubble in it's own time, and was followed by a crash that wiped out >70% of the market cap over the coming months/years.
Though it did recover, that doesn't mean it wasn't a bubble.
I believe cryptocurrency is going to be bigger than e-commerce is today. But it's not there yet, and it shouldn't be valued as though it has changed the world. It hasn't yet, and it's still a few years away at least from doing so.
