I guess being anti-crypto is virtue signaling now. Guess that means we're at the turning point where crypto isn't this cool magic money thing anymore now that the harsh light of day is being shone on the industry.
Or, I think more likely, is that the parent can't actually form a cohesive argument and is part of a group of people for whom the term "virtue signaling" has become synonymous with "bad" but is used to try carry more intellectual weight than it actually does.
