Please keep such low-effort hyperbole off HN. It's just so unnecessary and contributes so little.
[some group you dislike uses thing everyone has access to] is just not a useful statement.
What do we do now, ban all crypto currencies to force 'Terrorists' back into using cash?
Has terrorism gone up since cryptocurrencies came around? Did Bin Laden have access to crypto?
I'm not even a big fan of cryptocurrencies and think that the environmental impact of BTC is a heck of a lot worse than 'terrorists' possibly, potentially using it.
But I just don't understand what you were trying to achieve by throwing such an incendiary statement into the discussion with so little evidence to back it up.
