This happened today in PDAX, a Philippine based crypto exchange. just following this developing story. If you scroll through that Reddit thread you’ll find somebody purchased 11K BTC for less than .5 ETH. Rumor is that there’s a whale that fat fingered his 300K BTC and used a ETH/BTC transaction instead of BTC/ETH. The same guy who got 11K BTC turned around and sold it for 6KUSD/BTC today. The OP of the thread was one of the buyers and was able to cash out his 1BTC to an external wallet. PDAX limits 1BTC withdrawal per day so a lot of people were able to withdraw it. Now PDAX is going after them. However in their terms of service it is clearly stated “All orders executed are final.”
The title makes it sound lime they lost the key to the Bitcoins...
