Tulips bubble had an infinite supply.
.com bubble had an infinite supply.
ICOs bubble had an infinite supply.
NFTs bubble had an infinite supply.
The US dollar bubble and US debt has an infinite supply.
Bitcoin has a finite supply of 21 million coin.
Gold has a finite supply on earth.

That's why I call ICOs, NFTs and .com sites as digital tulips. Though 99% of these failed, 1% of these did become successful. Bitcoin is not a bubble because it's finite compared to the other bubbles. Bitcoin is compared to Gold because of it's finite supply.
