Okay so I have read about ethereum's asic resistance... it's designed to be profitable with GPU's and they dont want asics to "destroy" that like it happened with bitcoin and scrypt miners.
But I don't understand why it wouldn't be profitable? I understand that the Ethash algorithm needs lots of memory and that'S not cheap. But why hasn't a company just produced them in bulk for a lower price and made it profitable ?!

Like I see it, the current best GPUs can mine 46 MH/s (Radeon R9). And they're still profitable.
So what exactly is the problem with having a miner that has more hashing power, would the power consumption be too high?
How high would the power consumption of something like this be, I mean bitcoin miners have incredibly high electricity cost as well, why is this so different?


And another factor I read is that ethereum will switch to PoS "soon".  And once they do that switch, an asics device specifically for ethereum would be unusable.
I don't really understand the technical side of PoS and why that's the case, but let's just say this is true.
How do we know when exactly ethereum will be switching to PoS?
I have gotten the feeling that in the mining world, every announcement is always late. almost nobody meets their deadlines.
I have read some forum posts of people saying they wanted to switch until the end of 2016, others say it may take another 3-4 years. Why so vague?

I'm really just trying to understand why there's asic miners for like every major currency but not the one that's currently on the 2nd place of the market place.

At the current moment it can still be quite hard to mine with solar energy, and it might not make tht much of a profit.
I can't wait until the time comes that actually MOST mining will be done with solar energy. that would be awesome.

OP, let us know if you tried it and how your results / success were.

I think there's still a future here. I mean, let's not forget that ETH is still the currency with the 2nd largest market cap after bitcoin.
there is still a big potential for growth, and potential to earn big on investments.
Of course there need to be some changed and eth needs to become more attractive and popular, but as the mainstream interest for crypto and blockchain rises, I think it will come naturally

Yes I still invest in BTC. I believe that despite the spikes we are still far away from the peak. BTC still has such a huge potential , so we should use this current relatively low price as an opportunity t stock up, and not lose faith
