If pricing were part of it then everyone should have a low rating! Nothing being sold at retail will make a positive ROI even with free power.
And that makes any guide at this point useless. This might be the end of this portion of the forum considering it was the user coming here to discuss hardware that made it relevant. As time goes on there will be no more interest or users.
Why does it have to be about ROI?
Alot of people mine simply because they can...
It's not about the ohh shit ROI in 2 months to me.
It's about the ohh shit broke ROI 6 times over after a year to me.
It doesn't but you are not going to get 100s of people coming here to buy things that don't ROI. Games over for the home user and by default this forum will fade as fewer people engage in this hobby.
That is complete garbage and you know it.
There's actually more miners then there ever was.
Do you understand how difficulty works?
It gets harder and harder to mine to reach this ROI you speak of.
It requires you to get bigger and faster miners to compete.
If anything the Bitcoin Network relies on fast confirmation times and blocks to be mined so if anything all that will happen is the miners will turn into centralization or work together with other miners.
I don't see people ever stopping their purchasing of Bitcoin Miners nor do I see anyone stopping even SCRYPT ASiC Purchases now.
Your logic is flawed and obviously you have not been around since a Bitcoin was worth a couple of dollars each.
We will see who is BUYING but I dare say it won't be a public consumer at home.
Consolidation will continue and those people buying are not coming here to debate the value of one producer over another. This forum is becoming less relevant every day. What you will see from this point forward are the death throws of some companies and the continued complaint threads about the latest scam or legal play against other companies. Whatever is cutting edge is being developed for commercial customers not the small home user.
You are naive to think the same market continues today as it did in 2009 or 2010 or 2011 and so on.
