We have to stop fooling ourselves, Bitcoin, by design, is not fungible. Some already use this, some will do. Sadly, against us.
Bitcoin is fungible as long as people act like it is. If you treat Bitcoin as if it's not fungible, you risk that the payment you receive today becomes worthless tomorrow when you find out the previous owner had stolen it. Treating Bitcoin as if it's not fungible seems to be the most successful attack on Bitcoin so far.

BTC=1
BTC. The end.
Imho fungible means that no matter how hard you try, you cannot distinguish one BTC from another BTC.
Somehow I feel that you want to convince me about something. Somehow I feel that you see my post as an attack against Bitcoin. But what I've done was only to state the reality.
I would love to see everybody act like 1
BTC=1
BTC. But as I said, Bitcoin, by design, allows people make certain decisions. And some companies do that. And I don't see any massive boycott against them (although they'd deserve it).
As soon as a transaction has more than one output, it is impossible to say which bitcoin ended up where.
It's a very interesting point of view, 10 levels better than any explanation I've seen until now.
Still, we both know that before getting into a mixer, the chances are very high to have the full funds from a hack, for example.
And having blacklisting exactly when one tries to mix those funds may be more precise in detecting.. things.
And the others tend to already blacklist mixed funds as a whole (which is utterly stupid), or go by "shades of gray" (I don't know how to say it better) and by the rule "the stream's water can be considered clean if it went over 7 stones" (again, I don't know how to say it better and more concise).
Again, it's not a situation I like. I just state what I've seen/heard of.
Maybe we, as community, should start boycotting the services who don't go by 1
BTC=1
BTC. Because unless it starts hurting their business, they may do that more and more, to stay on the safe side, just in case.
