Well, to start with, "crypto asset space" is an oxymoron. There are no assets involved. Just the greater fool theory. One of the things that amuses me about crypto is the re-emergence of technical analysis, which has long been discredited and on its deathbed. Why now? There is nothing else for the chattering monkeys to talk about. No assets. No intrinsic value. No financial ratios. Nothing.
We own shares in basically all the stocks in the world (VTWAX). In each of those companies, there are employees working to make money for the shareholders. This money comes to us in the form of appreciated stock values due to the company's money being internally invested or used for stock buybacks. It also may come to us as dividends. It is these people, working away, who are responsible for the steady growth of the stock market. Some companies are more successful than others, of course, but the average is 5+% per year growth. That is why buy-and-hold works.
The point here is that there is new value continuously being created for shareholders and reflected in the market. That is the good that comes from owning a piece of a company. New buyers pay more than existing owners to the extent the employees of the company have added value -- retained earnings, shareholder equity -- or to the extent that management of the company have bought back shares, increasing the slice of the pie that each existing shareholder owns.
