Ask the people in the developing world using it to replace their countries' failed monetary systems. Ask the people taking out loans on DeFi platforms and not needing to worry about discrimination by some bank's underwriters. Ask the working class in my country and others who want what little savings they have to have at least some chance of appreciating in value. Ask the migrant workers in my country who are now able to send money home to their families without Western Union's predatory fees.

Cryptocurrency ain't perfect, but people are using it for its intended purpose, and it ain't going away anytime soon.
