Very much indeed.

Bitcoin will be used to settle international trade debts. And that is how much it will be worth. And there will be many other currencies.

But in the end, it will be a major currency for each large land mass. Mostly because of energy flow.

I believe money will become more... better, be much more a tracking of multiple energies, and not just labor/time/effort.

I believe in the future no one will go without needs, but we will not stop using money. It is a good marker to use for trading one's time.
