Few weeks ago I accidentally sent 20btc worth of razorcoin to a riecoin address.. and everyone made fun of me when I requested the developer some how code something for the next update that would return my coins. I was emotional and was not thinking clearly or rationally and it was a stupid request to even consider asking. I know it sucks but sometimes you just gotta take the loss. At one point darkcoin got attacked pretty hard when a hacker stole a bunch of coins and used it to crash the price of darkcoin. In the real world if something goes wrong, you can't just jump in a time machine and make it right.
