Yes You can but check status "Active(not listed)" and of course it means that anyone trying to check how profitable his mining rig is will get info about alt coins (for example ETH, ETC, ZEN, ZEC etc.) on the list but not about BTCZ even if it would be most profitable coin - and people are just lazy so they see "automatic results" and they just think ok "I'll mine XYZ coin" I believe they won't search more in "Active(not listed)" coins like BTCZ
