@Andre#, serious question: Assuming I wanted to trade on that exchange, and assuming (gasp! another leap of faith) that 3.5 BTC belongs to more than one bro, what happens when I buy the whole 3.5 BTC?
Do I need to send a bunch of separate money transfers to all the Anons involved, or do I just wire the whole shebang to arbitrator Anon?
...
Edit: Am I reading that (my) screencap right? There's 5 Euros' worth of BTC on that exchange, and 3.5 BTC if I want to use USD?

That's, like, a whole used car. Probably won't get a sticker, but hey, at that price, who got time for statist bullshit like safety inspections, amirite?
