If I may get you correctly bitcoin as active so use was is an insult to bitcoin because I believe you have also benefited in one way or the other about bitcoin even though you have any investment currently I believe for you alone to have access to this platform is a great benefits and privilege to you. I don't care how old is bitcoin or what activity it was used for but I believe the impact alone to the world is something unquantifiable compared to what they are using it for.
Illegal activities are also involved with fiat, have you thought of when there was no bitcoin what were those criminal or kidnappers do demand as a ransom?
Was it not same fiat money or is there anything else they demand? Even people loots physical cash and embissled funds yet you didn't mentioned those ones all you could do is to outline the bad effects of bitcoin.
