Solo mining for a usa miner due to new tax laws makes sense. I have 2th. I am mining with btcguild..
I move the btc at the .1 mark or about 1 time a day. my 2014 tax return will need to show every 0.10 btc entry made with the usd value at the time.
So that would be 365 entries if I keep my pace up. I can do this. I have accounting training and tax experience .
Plus 2th is too much to lose if it never hits a block at solo mining.
But if you have 1 ant s-1 have zip skill for preparing a tax return.
here is the breakdown .5 to buy one = 220 usd. power on under clock and undervolt 140gh at 200 watts = 5 k-watt a day or .50 to 1.00 usd a day.
so 220 + 365 = 585 the first year. that is at 20 cents a k watt.
second year is 365. that is at 20 cents a k watt.
no tax reporting unless you hit a block. a 25 coin block is about 11000 usd today. the downside is at the diff of 8 today it is 2800 to 1 to hit a block in 1 day.
