Hey mikey, I heard this argument many times before and it's of course 100% true! But - it's not a black-or-white situation. It's not like the ones with better circumstances (power cost, component cost, labour cost) DO make money and everyone else DOESN'T. It's just simply that the more costs you make, the lower your profit gets (and of course can go into the negatives).

To B1994, I would say: for Germany, 0.16€ is a sick electricity price and I haven't heard of lower prices there so far. The advice to sell that electricity that someone mentioned is actually not a bad idea. But it's of course a whole different kind of business which I have 0 knowledge about.

Regarding mining (anywhere): You want your gear to be as new and as cheap as possible. Especially with a still high electricity price, it would also make sense to try getting something as efficient as possible, and there, Antminers are hard to beat. But they'll need more service than other models.
As I mentioned, hardware cost can very a lot and now I'd say is a very bad time to buy them. Maybe catch a good deal in the next bear market or (pre-)order the next generation of miners as soon as possible, so you mine with 'new gen hashrate' before the whole network adapts to it.

Almost all profitability calculators take current profitability and extrapolate; that's where you get 1yr ROI predictions and after 6 months it still tells yuo 12 months or even 13. You'd need something that factors in difficulty adjustments (mostly rising) or just try to buy and mine at prices that - extrapolated - get you a way lower ROI, like 6 months or so (with the knowledge that it will stretch out due to diff increase).
