It’s the next level of risk up from people who buy stocks because the price is going up without checking the fundamentals. If all you do is hang around with other people hyping the same thing, it’s really easy to focus on the “number goes up” part and not want to be the person spoiling the party by asking about value.
Would you say the same if a pension fund ran with your retirement, since it is invested in some stock index, most likely in previous metals, and probably a slice in crypto?
I doubt those who think that in the end victims are partly responsible as there are things they could have done differently, would change their mind.
Remember, the claim isn’t that the traditional finance world is without problems but rather that people who deliberately seek out high-risk investments do share some responsibility when those fail. Someone who trusted Enron’s public audit reports was more comprehensively failed than someone who sought out a company specifically incorporated in the Bahamas to avoid compliance with US regulations!
