I would buy as many pennies as you can, because once Bitcoin explodes in popularity, everyone and there brother, is going to dump money into every Altcoin, in hopes of getting rich.
Keep in mind that the "Bitcoin rush" is a few months away, and BTC ATMs are becoming a huge story, and people are beginning to take notice.
My advice, is too buy all the cheap coins you can get, because those are the coins that most people will be blindly investing in; not many people will do research before buying the coins.
This is going to be a profitable year for us all.
