Damn, i've thought i sent RDD to a RED address on Cryptsy. Is is even possible to send to non existent address? It is very easy to confuse them on the current balance page on Cryptsy.

Sorry man! I sent some bitcoin from poloniex to my freaking reddcoin address at bittrexx and poloniex was able to get my coin back to me. I could hug them! See you on the moon reddhead!
sorry for my bad engrish

i actually didn't lost any coins as i
almost confused RDD with RED. Anyway, thanks for the help post allcoinminer, i hope this will prevent others from accientally losing RDD.
Also, poloniex ticker is REDD which adds to overall confusion.

I have also this problem on Cyptsy but thanks God have no too much lost and now shifting to mintpal
Ask Cryptsy to send to you private key from RED wallet import in your RDD wallet and you have coins.
/open NEW empty RDD wallet on ANOTHER computer to do this. DON'T play with wallet with coins. always backup your wallet.dat/
if you have key of WRONG reciving coin wallet (cryptsy wallet when you send coins) , then import that key in YOUR wallet you have coins. , i have same misteke with MYR, and MRY coin. and its working
if Cryptsy provide private key. off wallet where you mistakenly send coins.. (wrong reciving wallet)
