What happens if your friend Alice gives you counterfeit cash, you go to spend it in a store, and they confiscate it?
Counterfeit cash is more easily detectable, and if it's a good counterfeit it will probably fool other people too.
Maybe. I've seen stores uses counterfeit detector pens quite a bit, and in a few cases run the bills through a machine (usually only larger bills). Banks routinely run cash you deposit through fancier machines and probably catch more. I don't do any of these when I get cash from a friend, and I wouldn't necessarily detect whatever it is those tests are doing.
The point is, you can lose money this way, so losing money due to receiving bad Bitcoin is nothing qualitatively new. I'm not saying it is a good thing though.
..... how did we even get into counterfeiting?
Because the question was what happens when you receive Bitcoins from someone and when you try to spend them you find they are blacklisted and lose money. That's very much analogous to counterfeiting.
Right, this just might be the most stupid thing I've read all week.
If you enter a transaction that involves any type of blacklisting it is your own undoing and you deserve it. Bitcoin exists precisely to enable monetary sovereignty & bypass any of these stupid fiat rules. Government doesn't have any right to know or be aware of the existence of any wallet in my possession therefore any coin I receive I'm free to spend at its current market value, no matter what its history is.
I mean who the hell are we kiding here!? We have the USG currently trying to get their hand on every chip of all DNM and either keep it for themselves or "sell it" to their friends possibly over market price.
You think they really give a damn where the coins are coming from?
If you wanna use Bitpay, Coinbase, Circle and all them USG exchanges then by all means no one is stopping you or your rapist's interests but Bitcoin don't play these batty-boys games.
But then don't you dare fancy you using Bitcoin.
Cause Bitcoin is a peer-to-peer market and what you're doing doesn't sound like bitcoinating to me.
Try telling THAT to every new bitcoin newbie and see how many of them run away.
There will always be people who don't know any better and it happens to them. Bad things happen to good people all the time.
You can't stop all of it. But to say "you deserve it" is a bit hard especially if they are just trying to buy something with bitcoin or convert out to buy something with fiat.
