> The same logic though could be applied to startups or any business. The first people in do a large amount of the work in helping it grow and are rewarded for that. Maybe too much but that’s hard to quantify.
With a business where you hold shares, the business generates cash flow. That cash flow is invested in the business, in share re-purchases and in dividends. This cashflow increases the intrinsic value of each share of the business. The expectation is that holders of equity will be rewarded through the future performance of the business.
Those early folks are rewarded by people who derive value from the system - the customers of the business, whoever they are. They're rewarded for building a business not shilling their equity. The equity value is a consequence of the business being built.
On the other hand the sole source of gains from crypto come from future buyers. Worse, miners, especially on PoW chains, have to be paid and so constantly extract huge quantities of welfare from the system. With Bitcoin, it's something like 20-30 million dollars per day. That gets turned almost directly into CO2 and e-waste. 67MT of CO2 and 6.5kT on e-waste per year.
Early holders are simply rewarded for shilling, hoping someone else will grab their coins for a higher price. It's just an MLM scheme which yields zero intrinsic value.
Ergo, bitcoin is strongly negative sum while equities are positive sum vehicles.
The thing is, most people don't understand the economics or the fundamentals. Those who do get it (especially bankers, ex-wallstreet folks) intentionally downplay it rather than educating folks because they know their paycheck depends on people not understanding. The community pretends or fails to understand and looks the other way. They're all convinced they're "getting in early, on the ground floor of the future of money" - classic MLM stuff.
They're really only superficially similar, in the sense they're traded on brokerage-like services.
