Then you are simply not very well informed. Problems with BTC transactions have happened repeatedly. Here is a great example of a successful 10k double spend during a chain fork: https://news.ycombinator.com/item?id=5372956 It was was made possible buy slightly different behaviours in the different client versions. The core developers had to get on IRC with the miner using the 0.8 version and talk them into giving up their (correct) chain to resolve this problem. Currency of the future!

This incident had nothing to do with zero-conf txs. In fact okpay did wait for multiple confirmations, and was still hit by this $10k double spend!

This whole thing was possible because of an accidental fork of the chain which lasted a few hours. This is the only accidental fork that occurred in the last 3 years.

That was 755 days ago. Bitcoin updates are handled much more carefully since then.

This was not retail.
