Alcoa moved most everything they do offshore so they didnt have to deal with EPA regulations and all that other fun environmental protection stuff the civilized countries have implimented.
I think there is confusion between us over the terminology. I am not sure what you consider a 'smaller miner/farm' as people on this site tend to call their 10-20 unit setups a farm.
*goes around and counts*
As of right now, I have 5 ASIC and 15 dedicated GPU rigs of various types mining, and the machine I'm typing this on part-time mining makes 21 total units.
The BULK of my income comes from the 5 ASIC and 11 of the various GPU rigs - the other GPU rigs are entirely "left-over" parts from my Litecoin GPU mining days or "what I had lying around" and while they're profitable they're not making a lot.
I would classify this as a "small farm" or "small miner" setup.
My TOTAL investment is well under $30k - I think it's under $20k a bit but haven't crunched the full numbers for last year yet.
A fairly large chunk of the "investment" is paid off, it's my more current *higher profitability* gear that I've not had long enough to be completely paid for though.
I wasn't aware Alcoa moved so much offshore but I don't find the idea shocking.
I do NOT believe that 100k invested in Bitcoin right now would return more over the next 2 years than getting a serious well thought out small-to-mid-sized mine going with that same money. The BULK of the recent Bitcoin price rise came with the Chinese exchanges were allowed to start accepting payment in Yuan for Bitcoin purchases back around November a year and change ago - which was a ONE time event that more than doubles Bitcoin pricing in a month and has allowed the continued weakness in the Yuan to fund ADDITIONAL Bitcoin price rise since then (excluding the short-term panic drop when the Chinese "Central Bank" (owned by their government) turned around and announced that they decided to "investigate possible market manipulation and other issues" with the major Chinese exchanges).
If I had 100K to work with (INCLUDING my outlay for the current setup), I'd find a much bigger place with a lot more electric to work with and move a lot more towards doing what I WANT to do, without having to worry about continued growth just to maintain my current income level. Among other things, ALL of the pre-RX AMD stuff (and possibly my pair of RX 470s as well) would shift to hammering out MooWrapper/Dnet blocks (I can almost break even doing that via GridCoin, but can't afford to do so at this time)....
