Yeah, this article's consideration is for the "bitcoin as an investment" class. It also looks like a sales pitch to convince people to continue investing in the inflated equities market.

"For example, we can compare Bitcoin’s price to a fund that just tracks the performance of the overall stock market, like the SPDR S&P 500 ETF. When you adjust for inflation, that fund was worth a little over 1.5% less on Tuesday than it was three years ago. That means if you bought $10,000 of Bitcoin at its peak, your money would be worth about $9,050 today. If you bought $10,000 of the SPDR S&P 500 ETF at the same time, it would be worth $9,850. Inflation hits old-school investments the same way it hits Bitcoin, but this time around, you would have been better off investing in the regular old stock market."

What a joke!
