To follow up this question: Isn't that just a gamble too? I buy a company at 10, it goes up to 20, should I get out? I think it will get to 30, the next day it goes to 2 and soon delisted.
I can vouch, I have done this. I have no idea what I am doing.
If you buy at 10 and it goes to 20, sell half and play with house money if you are worried about it.
No, that's like saying all lineages die out; there's no reason a company shouldn't continue operating profitably indefinitely.
Who mentioned "should"?
Not strictly true. Large traded S&P/FTSE companies are more likely to get bought out then fail outright.
In theory, companies pay dividends, and the price of a stock is effectively the time-discounted value of all future payments (including any final sale).
Separating that from the “bitcoin” part of a stock’s price is, of course, the major question.
That's why you don't put all your eggs in the same basket.
