Definitions are not an argument.

Anything can be used as money.

The "best" money has certain qualities, ones you get from metals being coined. Ones bitcoin has.

The "dollar" technically isn't money, it's fiduciary media, but the minted paper is treated as money.

You're dragging me off topic.

My point is, what would you be doing right now with your "earnings" if bitcoin didn't exist?

Some would say they would be saving in gold and silver.

Some would say they would be investing in securities.

Most, in reality, would not be saving anything.
