If you want to check/move your yec coins, use guarda wallet. I used it, it works and you don't need to download whole blockchain, which is huge. I also tried to download blocks from torrent file, but I could not import them into official wallet, it just didn't work. So I used guarda and that works fine.

You can buy and sell yec coins on citex exchange. Now please start dumping so I can buy them back cheaper than I sold them.. :p
