For Bitcoin, maybe. Try Litecoin (LTC) or Peercoin (PPC) - they’re the #2 and #3 cryptocurrencies, respectively, and both have plenty of room for miners.
A couple of weeks ago, 1 LTC went for $4. Over the weekend, it shot up to $40. It could go considerably higher once mainstream bitcoin exchanges like Mt. Gox and Coinbase start accepting it.
