Whether or not a technology's pros outweigh its cons is some appropriately weighted average across all the people that it affects. The person who gets hit by crypto-enabled ransomware likely feels differently from you.
I also think there is some moral weight to particular benefits. Dealing with unfair economic systems is definitely a "better" benefit (for some definition of good) than those people whose benefits are currency speculation or ransomware.
