Is there a limit to how many shares a company can issue? No, a board can technically issue shares unto infinity. There is no guarantee of scarcity, no guarantee they will not raise more money.
That company would have value whether or not it was explicitly sold as a stock. The value doesn’t come from the stock.
So when a company has no profit but a high valuation, is this the market correctly discounting future predicted cashflows and giving a company fair value, or is it some sort of scam? Ex: Is NKLA actually a $5.2b electric vehicle company? How about the spade of Chinese IPOs that ended up being vaporware?
Cryptocurrency removes the underlying asset and simply sells shares of artificial scarcity.
The scarcity isn't artificial. It's mathematically provable, open source and auditable. If you think you can manufacture "fake" btc on the blockchain, feel free to try. If you think you can successfully fork and create a whole new chain, you're also welcome to try.
It’s only as valuable as what people decide to trade it at, because it doesn’t represent ownership of anything other than itself.
This is actually factual for anything in existence. A piece of bread. A $100m painting. You're starting to figure out what peculiar creatures humans are.
