This argument against bitcoin is about as stupid as someone arguing that they won't use monero because it is used for buying drugs illegally. Money is amoral. I don't care what other people do with bitcoin or monero as long as it doesn't harm me. If the money can help improve my life then I will consider using it. Do I like the SBR? No I don't. But why should I give a shit if people I don't like are using bitcoin? I don't like my neighbor but he loves steak. Should I stop eating steak too?
