I've been working on a more formalized posting of how to subscribe, and at some point I need to get a link to it put in a prominent position on the blog, but for now donations of one of these coins should suffice. You can do the math to determine roughly how much $5/$10/$30 is, or go with the rates I list below (which might end up being too cheap/expensive if the prices change much):
BTC: 153qS9Ze32hnV3fwirZLWNka4wBAowc21E (0.01/0.02/0.05 BTC)
DOGE: DD9iTWf8diPkvKdB8roPJepTyp6BGVQtct (6500/12900/38500 DOGE)
DRK: Xd3EaCJg6G8ZnGuKkpvwyRMwyHzbaRDnob (7/13/39 DRK)
LTC: LfCLyykrNFftzpdWejR73hf478ZtBzQ9jE (0.32/0.64/1.9 LTC)
MAX: mf5DXTLiZFCnJC2x13MXSyigyUjmBnrwjG (27/53/158 MAX)
MRC: 1Ctnz6cHcMYiF9fz2pyd6orFuo1mDhKdWj (810000/1620000/4840000 MRC)
VTC: VaNuRCj73JVAwR1YMnt8CXaqoiPgykiMTk (4/8/22 VTC)
Moving on, I've listed roughly the same PC quite a few times on my blog, but I'm going to go ahead and call this my "baseline mining PC" for now. It consists of the following parts:
|GPUs||3 x Radeon R9 280X 3GB||$1,200|
|Motherboard||Gigabyte GA-990FXA-UD3/UD5 AM3+||$137-$166|
|Processor||AMD FX-8320 Vishera||$154|
|Memory||2x4GB DDR3-1600 (desktop)||$77|
|Power Supply||2 x Rosewill Capstone 750W 80 Plus Gold||(Two) $200|
|Storage||2.5" 60GB Kingston V3 SSD||$59|
|Risers||3 x x16 to x16 and/or x1 to x16 powered||(Three) $13/$9 each|
|Case||Build it out of wood or PVC pipes||~$40|
|Total (price range)||$1906-$1935|
My recommendations for mining are based off of that particular build, and the goal has mostly been to try and choose coins that can pay that off in four months or less. Note that it's possible to add a fourth GPU quite easily, and the two 750W PSUs have enough power to do that, so technically you could spend about $2320 for a system that's 33% faster than the above and it would end up being ab it more efficient. Anyway, right now, the market is in a bit of a slump, so the best I can do as around $13-$15 per day. That means it will take more like 4-5 months to break even, provided prices don't drop -- but prices could also jump up again.
Consider LTC; Litecoin launched and went up to around $4.50 per LTC last April, then it quickly fell to the $2-$3 range and stayed there for much of the year, with a drop down to as low as $1.11 at one point. Many were proclaiming the end of LTC...and then November happened and LTC shot up to $48. Those who had strong hands and held until the bubble came out with some amazing profits; even if you sold at $20-$25 (which is what I did with the LTC I still had), it's hard to complain. Well, we're now repeating that with most cryptocurrencies. Sure, prices are higher on LTC and other coins, but so is the difficulty, meaning for every dollar spent on a GPU you're looking at three months to earn it back. Save the coins, though, and I suspect in another year many people will be looking back thinking, "I wish I had kept all my VTC until it hit $50!"
Anyway, if you want to join in the fun, at least some of the prices for hardware have come down. The same system as above last month cost around $2020, so $100 less now. GPU prices are still way over MSRP (by 30% or more), which oddly enough appears to be more of a US phenomenon. I have friends in Europe that are able to get GPUs for less than what I have to pay, where normally it's the exact opposite. Their power costs are still a lot higher, so I suppose that's a small consolation.
