Crypto is a speculative asset. It was made and promoted itself as money but failed completely in that aspect.
On paper, it's a perfect crypto. Really fast and fee-less transactions, proof of stake avoids the environmental impacts, completely pre-mined, distributed as equitably as you reasonably can, and truly decentralized.
But it has one major flaw - no way to get rich quick. No celebrity hyping it up. Nobody is "in it for the tech", it's all a glorified game of chicken
