I use bittorrent to download and distribute Linux distributions. Every bit and byte on my harddrive, from the OS to the applications to the data, is either open source, written by me, or paid for. I don't need people who should know better to draw parallels between my completely legal and moral use of bittorret and copyright infringement. And people who have perfectly legitimate and legal use of cryptocurrencies, of which there are many and some might argue more than the use of cash, do not need people who should know better to draw parallels between their usage of technology and anything illegal or immoral.
