It only counts if it's something that's riskier than it seems. Everyone knows cryptocurrency is extremely risky, the problem in 2008 was that these packaged mortgage products were far riskier than they appeared, far riskier than they were rated by Moody's, S&P, etc.

Maybe you only meant your comment as snark, but if not it's important to understand the difference between simple risky investments and potential structural flaws in the finance system, like the ones we saw in the financial crisis.
