the only irrefutable bitcoin critique I always hear from people is: "I'm socialist and I dont like freedom, especially other-people-freddom ---> so bitcoin bad" (most of the time is implicitely masked under other words).
Every other critique I heard was always misinformation and fud, easy to refute by correcting their misinformed bullshits.
But the "I'm socialist..." is the only critique that I cant refute and I need just to accept. I can only say I disrispect you as human and GFY, but you are right, socialists cant like freedom money, is by design and you need to choose: or one or the other.
