I ain't no stock market trading guy with a "portfolio",.. But here's how I see it.
And y'all feel free to correct me if I'm wrong.
The commodities traded on the dark web are child pr0nography, stolen identities, drugs, insider trading information, hit men services, sex slaves, black market organs, etc.
So if this bitcoin currency is limited to a certain amount worldwide, when you buy it as an investment, just to park it in some electronic bank, you remove it from circulation.
If bitcoin is the only currency the dark web thieves and pedophiles can use, due to it supposedly being untraceable, by removing some of it from circulation you're increasing it's value.
Wouldn't this therefore also increase the value of the illegal commodities being traded? And by increasing the value, you increase the motivation for people to produce more of it?
