Last night I have sent out 20 BTC by mistake. How do I revert/cancel the transaction ?

Update: Thanks to the forum members, I found a way to contact the address owner. Now, I have asked for a refund - http://forum.cloudmining.website/viewtopic.php?f=3&t=42. Surprisingly, it took one minute for me to send the coins to them and even after 24 hour is over, they are asking 24 hours more to take the decission to return my coins !!!

I just saw that you edited your thread, glad that they answered you . Let us know and keep us updated with how things does. You still may have chance to get your bitcoins refunded ...
Still ..; some people are saying that your Bitcoins have been obtained from Bitsmap hack ... If it's true then you may not get refunded at all.
So I will ask you straight , did you got your 20BTC from Bitsmap hack ?

These coins have come through mixer before reaching out this address. It seems, the person from which he bought coins at lower price mixed his coins through mixer and hence he received those coins. Details: https://bitcointalk.org/index.php?topic=939199.msg10292903#msg10292903

So the guy he bought the coins from is the Bitstamp hacker?

No. He might be another scammer, drug seller/addict or just mixing his coins for anonymity. His coins are now in mixer reserve and OP has been paid from mixer's own reserve, where bitspamp hacked coins were residing. This is how it works: https://bitmixer.io/how.html
