Don't forget anonymous payments. Lots of vendors selling legally questionable (or illegal) things only take cryptocurrencies. I see that as a huge boon for these industries, who would otherwise have to figure out credit card processing, bank transfers, or being repeatedly shut down by Paypal/Venmo/etc.

Not anonymous (mainstream creeptocurrencies are traceable by design!) but censorship resistant. Yes, this is the ONLY use case for the buttcoins.

The problem is that for every successful weed and nudes sale there's a million ransomware attacks, scam calls, and absolutely fraudulent "investments".

completely false, privacy coins command billions of dollars in market cap, Monero alone is currently worth 2.2 billion and will likely continue to grow.
