That is already known to false in most cases.
Well you can trace it to some degree to a point of origin ( address ), but you don't know who is the owner of that address, as in name, DoB, and so on...
In most cases the NSA and the "Club" do know this. They can get it from your ISP and IP address or by correlating emails, spends with credit card from same IP, etc, etc, etc.
You have to be both expert and lucky for that not to be increasingly the case.
VPNs, new email address that is used only for bitcoins, you can make fake documents ( PS ) and use them to create accounts and send them if you are asked for them, open bank account on a fake document and so on...If you have nothing to hide, as in, you trade it just for sole purpose to make money, then that doesn't concern you, but if you are selling drugs, guns, sex and so on, then well, you will probably be smart enough not to give away your real identity.
So then we agree that the anonymity in Bitcoin is not mainstream, so it has nothing to do with the price valuation. I don't think investors could justify such huge projections of currency value if only illegal markets are to be the norm.
Cannabis is illegal in my country, so the price is high if you wanna buy it and you will get a jail ( probably ), in Holland it's legal, you can trade it, buy in coffee shops, smoke in the street. Apply that to bitcoin, only the larger part is sued for that "illegal" stuff and the rest for normal trade. Price is dictated by many things, in this case one of those things is the need to buy something you can't in relative security.
I wouldn't invest in Bitcoin is this illegal use was the dominant justification.
If drugs become mainstream, I will move away from society. That is once reason I moved away from the USA and stay away from Thailand (even though they have strict drug laws, they seem to attract too many foreigners who use them).
I understand and support individual freedom, and maybe drugs are going to become extremely widespread now with Bitcoin, and so maybe that is a wise investment.
However, I am hoping society will continue to fight drugs harshly as they do here in Asia for the most part with life and death sentences.
So I guess I will choose to remain ignorant of such a market, and assume it will remain insignificant.
Note I am not in favor of forcing all countries to be harsh on drugs. I have a friend from NL and he was doing drugs recreationally all his life. Unfortunately now he is dying of Leukemia, probably as a side-effect of the drug use. Well I guess he enjoyed his life. We all have to die someday.
You are agains't drug use? Do you know a place on earth where every person is "clean"? Drugs have always been and always will be. And as i read most of your threads and posts i thought that people with an higher iq are able to see the konnex why the US (and other cons) called a war on drugs. If drugs would be decriminalised worldwide the drugcartels (cia,etc) would lose a big amount of their income. And if that money would not be spent on prohibition, lawenforcment, jails (which is getting quite a profitable branch in europe) but on education we would have a lot less problems.
And Leukemia, probably as a side-effect of the drug use? Mkay.. Which drug exactly?
