I remember that in yobit, there is one coin that is too expensive, the named of the coin is nanox and if you want to buy nanox, you need to have 3.92400000 btc per one nanox. Besides that, I know the other coins which are too expensive like nanox, the coin is 42 coin, and you need to have 3.28033914 btc per one 42 coins, and the market is in cryptopia, livecoin, and tradesatoshi. You can check it by yourself and see the most expensive coin, and it's not bitcoin.
