CoinTerra seems pretty awesome. They also have insane (or legitimate, if you prefer,) credentials. In light of this, would it be smart to purchase ASIC Miner shares? I don't know anything about ASIC Miner's r&d department. Will they be able to keep up, or will they slowly become obsolete, with "pro" players like CoinTerra advancing on the market?

I'm considering putting a substantial sum into bitcoins. What would be the smartest route? Hardware, shares? There's a ton of vectors one could take, sometimes it's a bit nauseating trying to consider what investment route to take.
