You've fundamentally mistaken what those large companies are. They're basically dividend stocks, not growth stocks. No one is expecting them to grow much.

Those companies make money with their customer base. Coca Cola has the ability to turn 40-cents worth of water, sugar, and flavors into $1 dollar worth of sales. Not only that, but customers are happy with this exchange (and will likely keep making this exchange... at least until people stop liking the taste of sugar).

Even without growth, those companies are insanely profitable. Because Coca Cola has a 3% dividend (and its assets are likely inflation-protected), they're a very safe bet.

BTC makes no profits. In fact, the entire BTC system consumes tons of electricity constantly. So we can see that moving BTC around costs real resources, but no one seems to have explained to me where "money comes from", aside from a greater-fool.
