Assuming a static BTC value you
maybe correct, but it was only a month ago that 1 BTC = ~$650 so it is extremely difficult to speculate on BTC value and mining.
I will gladly invest in your crystal ball that gives you the ultimate knowledge.
FYI, this is no longer profitable. It currently costs 6.4 BTC and at most you'll get back 5.5BTC with 17% difficulty increases. At most, you can hope to break even by selling the miner.
Jeez why is everyone so defensive? Just giving a heads up. All I'm saying is that if you were to invest money now, it would probably be much better spent buying BTC. You will end up with more BTC in the long run.
If you buy the miner, it would currently cost $2900 or around 6.4BTC. You will mine at most 5.5BTC and if you sell the miner, maybe you can get 1 more BTC. Maybe. It's a losing deal no matter how you look at it.
