It's a really poor metaphor, though. ICOs are stupid, but really easy to avoid (just don't put money into them). Certainly not "awful" in the way losing a loved one to an early, excruciating death is. They're not deadly and they don't "spread", at least not by any means remotely comparable to how cancer spreads.
It's not like the author works with the metaphor, either. The word appears exactly one time on the page, in the title. It's pure clickbaiting.
