if yobit did'nt receive my findcoin, and then where myfindcoin go??
Did you send it when there was a wallet update & you were on an old client or when your wallet was still syncing ?
Try -rescan when starting the wallet & also try repairwallet in the FindCoin Console.
EDIT: Also did you send using the new FINDcoin or the old FINDyoucoin wallet ?
