Miners look at btc  return, not usd.   Or at least they would if they were in it long term.

Last stabilization was at 100...    Maybe 150  this time?

 How did you start a crowd funding endeavor without knowing what you want funding for?    I don't understand what the point of storing anything but yourself in a nuclear bungee l bunker is.

If time is of the essence because of the btc  to usd rate then arbitrage right now.   Say you expect to get $1000  refund,  just buy $1000  in  Bitcoins and then when you get the refund sell those to usd.

I know you'd love to get a refund based on btc,  but that's not possible if bit pay converted everything to btc for steamboat.   he's not going to  sell his  house to pay you.

I don't think you need to unplug your HDD, but it's not going to hurt.

There is a small problem though -- your computer doesn't have very much randomness when you just boot from a live cd and generate your address right away.  So you could give it an hour of doing random stuff to generate some randomness if you were really paranoid.

And you could pre-download the key generation software, so that you don't have to expose your computer to wifi at all.  But, of course you'd have to be sure the computer you used to do that wasn't compromised.

I've had to increase this on a number of ubuntu systems for various reasons, I think it's just set way too low for non-desktop work.  So don't worry.

If you're going to go through all the trouble of setting up an offline computer it's just silly to put your wallet into an online computer.

There's nothing manual about it, it's just one command.  You can even check your work with diff.

I wouldn't, it's not worth the risk.  Just spend a few bucks and get a dedicated USB key for your wallet.  There's no point in making a wallet on an offline machine and then sticking it into your online machine.

That power supply can only put out 500W at 12V, so 8x60W will be cutting it close.  If the PCIE wires are too thin to carry all your power you can just take it off the molex connections too.

It just takes two seconds to encrypt your recovery key, there's no need for this in armory.  Just do it yourself if you want that.

The "value" of your refund isn't changing, it's the same amount of US Dollars that it always has been.

Hopefully it would be used along with your password, instead of stand alone which would be silly.  But the main problem is they'd have access to your secret if they had access to your wallet.

That's just as legal as money laundering.

This is true -- to use google authentication you have to store the secret on the same computer as your wallet.  If someone can get your wallet, then they can get your secret.  But it can be used with PAM to secure login to your computer, so that someone could only get your files by physically getting to your drive.  I wonder if you can use google authenticator with an encrypted home directory.

Maybe there's some microscopic entropy change when finding the right nonce from all the possibilities.

The only way he could refund based on BTC paid would be if he only converted 75% of BTC to USD, which would be silly.  So if you paid $100 for assembly and get 25% back you'll get $25, or about 0.12 BTC.

0000 is just as likely as any other 4 digit number

Yes you paid in BTC, but it was priced in dollars.
