The article (or, rather, the commentary in the link above on the article) talks about the fallacious notion of "market cap" in regards to cryptocurrencies. That is to say, e.g., multiplying the number of bitcoins in existence times the current market price is a silly metric because the entire market would never be able to cash-out at that maximum price. What I was wondering was: is there a better number? e.g., is the…
Amy Castor - "Yeah, market cap is a meaningless number. It assumes everyone bought at the current price and could cash out at the current price."
We could just as easily apply that basic logic to any security. Amazon(AMZN) is ~3275 a share with a market cap of ~1.668T. That also assumes everyone could cash out at ~3275, but the reality is if selling pressure is higher than the buy side demand that selling shares will drive the price down as buyers would be able to continually bid lower. Eventually it would reach ~0 share price and effectively a 0 market cap.
So in that sense token market cap is a fair equivalency. What makes a dollar worth a dollar? Crypto value at any given point in time is just an exchange value against fiat currencies. This isn't much different than an exchange value between USD and the Ruble; it will fluctuate.
