Dragon kid! I hope you understand the risks before you invest your money! Bitcoin hardware are investments!

Investments are priced based on risk preference, expected payout, and discounted by time, and liquidity. Are you familiar with expected values and discounting? If not please learn about them! If yes then read on:

ASICMiner is overpriced! Because probability to deliver is almost 100%. It's a sure thing, very little risk. The expected BTC payout is depending on what you think difficulty increase will be. Because lots and lots of people are paying ~3.5-4 BTC that means most people believe difficulty increase won't be that much as 70%, and value low risk.

Cointerra is so cheap! Because probability to deliver is very low. It is also far into the future. The more risky and more time, the less valuable. If you put your money into Cointerra pre-order, there is a high chance delivery will be delayed. Then every day you wait is lost money. So risky! But if you get lucky it's so good!

Bitcoin hardware is not the most efficient market, but it is still good enough to help you decide what you want. If you are OK to take very risky investment with good reward, do Cointerra/fast hash/whatever preorder. If you don't want to take any risks with your money, do ASICMiner. If you want to do something in the middle, I suggest BitFury.

Good luck.

I have done a LOT of reading about this exact topic and this is good advice in my opinion.
