Tulips bubble had an infinite supply.
.com bubble had an infinite supply.
ICO bubble had an infinite supply.
NFT bubble had an infinite supply.
The US dollar bubble and US debt has an infinite supply.
Bitcoin has a finite supply of 21 million coins.
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.
That's all correct although I often asked myself whether it is 100% known how much gold there is on Earth. Yes it is finite of course, but do scientists or the respective companies know how much gold there is? I think that might be another advantage because with Bitcoin even my grandma knows how many there will be, but with gold I think hardly anyone, if anyone, really knows. Couldn't it be possible that somewhere in the sea a couple of miles below the surface gold could be found? To me there is still an unknown while for Bitcoin there is not.
