>You can still buy a sub-$2000 mining rig that will basically pay for itself in a couple month
No you absolutely can't. About 6 or 8 or so weeks ago I was making about $4 a day mining scrypt coins. Now I'm making $1.50. I don't think it is going to be profitable 6 weeks from now. When Dogecoin first exploded I had several $15-$24 days. Right after I first started there was actually a graphics card shortage(!) because of the interest in mining.
My graphics cards haven't been paid off yet with just mining, and I don't think they will be. That's not a problem for me, because I can sell one of them, and keep the other, which will pay them off.
If you don't already have the PSU, CPU, MOBO, etc, you are wasting your money building a mining rig, especially now the profits are so low. Only buy a graphics card if you want the card for other reasons. Those mining profit calculators way way way overestimate.
EDIT: My system has 600 kH/s hashrate.
EDIT EDIT: Even 6 or 8 or so some people on the litecoin mining subreddit were very confused about people who were building expensive mining rigs and pointing out how those rigs will never pay for themselves.
You need to change what you mine to whatever is most profitable. If you only target a single, popular one then yes, difficulty will increase and profitability will probably decrease. See http://www.coinwarz.com/cryptocurrency/
Hahahaha. Yeah. And I do, which is why I said cyptocurrency not a single one. Those profitability calculators are a joke, each one has a completely different ordering. My point was profit is going down for all coins everywhere, there is no secret magic to get back the profits I had 8 weeks ago, and with the exception of doge just around Christmas, the trend is continuing downwards for every coin.
altcoins cannot be forever profitable as basic economics tells us this.
