Why don't you just mine at http://solo.ckpool.org/ (run by the developer of CGMiner) or solo mine through Antpool? Both are easy to set up, and would save you 0.15BTC.

I read about someone who set their S1 to mine only during low cost energy hours. (middle of the night) He set that up pretty easily by connecting the S1 to a block heater timer and setting that to only run for a few hours a day. That could be an option for you as well.

Adding onto what os2sam said, if the top ASIC does 6,000,000 MH/s, then this ASIC would be about...

300,000 times faster than a quad core Intel CPU and 8571 times faster than a Radeon 7970 GPU hashing at 700MH/s.

Then there's efficiency as well, obviously ASICs are much more efficient than anything else that can hash.

Try WTCR.ca. They accept credit cards and ship worldwide.

Exactly. Keep a small amount of bitcoin in an easily accessible wallet and them keep the rest secure on your Trezor somewhere safe at home.

IIRC you can't turn off the sound in the software,  but if you really wanted to you could probably remove the buzzer from the circuit board.

I'm sure the Pi would have been a profitable miner on it's own with the correct cooling, but of course those days would have been before the Pi was released. 

Congrats on finding a block! That's super impressive with just a single S3. Funny how it displays the best share as 0 though - the number must be too large to display on the Antminer status page.

What country/state/province are you located in?

Could try and make something like Silver Wallets have going. Link: http://www.silverwallets.com/

You buy the physical coin, and then put your own address "on" it.

I assume you found the password? All funds were moved from that wallet on the 14th.

Interesting, haven't heard of the BTChip before. I'll have to look into it, seems like a great alternative to the Trezor after a few looks at it.

You could look into buying a Trezor. Very secure wallets but they're a little pricey. ($120 IIRC)

Aha makes sense!

Seems correct, I can't sign a message from an un-used address yet, but the addresses that I've used sign fine.

Just received my Trezor today! Very happy with it so far.

One question though, I don't seem to be able to sign messages with any of my receive addresses. When I click the "sign" button, nothing happens. I've tried multiple times, and waited a couple minutes between tries. Any advice on how to get this working?

Edit: Nevermind, works now! Just sent a transaction and it worked after that - maybe it needed my PIN to be entered, which I did to send the transaction?

This sounds like a good idea.

I can't think of any CPU only coins off the top of my head right now, but if you could use these servers to offer people a service (ex. VPN) then you might be able to make some money off of them.

I wouldn't go for it - at the current price even with free power chances are quite low you'd be making money on an investment like that.

Seems like the days of mining are over for small miners unless you have free power and a cheap source of miners, then you might be able to make a little bit of profit. Another option would just be investing in bitcoin directly, if you feel that would be a good investment.

I connect mine to the 12v pin and ground pin of a molex connector and that works fine. After 7 days of running steady all connections are cool.

If you don't want to use a PC PSU to power it you could look into a 12V/5A power brick - that should work to power the R-Box.

Well the difficulty right now is about 39 billion so it probably won't drop to 10 billion, ever.

Does it stop the process when the text file is busy or continue on? I don't think it should matter much.
