ideally you would keep one offline, it never has to see the internet. ever.

as long as you know the wallet address.......the networks puts the coins there

as far as I understand it
I see how that would work for hoarding but how do you sell them in that case?

well.........you could store a VM from virtual box, virtual pc, esxi etc, in a encrypted folder, and only power it on to make a btc transaction

You can't be 100% safe, as soon as you need to spend some BTC, you'll have to connect the wallet to the internet.
You can improve security by setting a password for the wallet. (there's an option for that in bitcoin-qt). Just.... don't forget the password
It will as you that password when you try to send BTC.

So that should help if somebody gets ahold of your wallet.dat.
But if they also injected a keylogger on your pc... byebye btc.

I keep my real wallet on a vm, with a very long pass-phrase. Like-

sonya sells seashells at the east bay seashore with her puppy ryver

Obviously that is far from my actual pass phrase, but the idea is to make a very long strong of words that you personally can remember but nobody else would think to try, and include at least a few names or made-up words that wouldn't be known to anyone else, like the dog's name ryver.

But of course, a key-logger will still get you, if you enter the pass-phrase while infected. So, if you are extra paranoid, setup bitcoin-qt on a newly built machine that has never been connected to any network. Set your pass-phrase, and send your bitcoin to the wallet. Now leave it alone! If you never type your pass-phrase it can't get key-logged.

Yea, unless one thinks that LTC will be more profitable than BTC in the future and hangs on to the LTC coins until then, there is no reason to mine LTC currently over BTC. IMO, to make up with the instability of the LTC pools, the more "picky" LTC is about mining, etc LTC profitability needs to be a good 25% or more over BTC to make it worth mining LTC over BTC.

Side note: Back in it's infancy (summer 2011), BTCGuild was just as unstable as LTC pools are today. Amazing what a couple years and probably a decent amount of money made can do for stability.

Not true. As of today. lol. This was almost true yeaterday. Today LTC has jumped in price to over $4/LTC and 0.028/BTC.

My very stable pool i use, www.give-me-ltc.com is running at 284581 paid shares so far with only 4515 unpaid stales (1.59% stales) and only a 2% fee. So mining costs are about a steady 3.6%.

Playing with their calculator today @ 404 difficulty I am pulling in near $5 a day now off a single MSI 7950! This was under $2 at the low point last week and has averaged for a while at $3 so we have make a break now upwards.

Have converted some LTC in BTC, but hold most in LTC still and have converted none in FIAT yet becuase I have not yet had my credit card bill or any new power bill since I started up 3 weeks ago.

Way more profitable than BTC now again!

You don't. Keep them offline, forget about them. 10 years later you connect it to the network and spend 2 BTC to buy a small private island.
I guess that is one way of doing it. As a general rule when it comes to investments I like to hoard 1/3 in case prices go up, sell off 1/3 that goes to paying running costs and reinvestments, and sell 1/3 that goes towards improving my quality of life a little. I don't make money for the sake of making them you see. It will take me longer to buy that private island but I have more fun waiting for that day!

I will see what I can do for safeguarding my coins and miner tonight. Thank you for the advice.

Yep, crazy how the price jumps around. As of this post LTC is around 25% more profitable than BTC at mining. For me that is on the edge of wanting to switch back to LTC.

Yeah I was selling some to cover costs, and sold some to fund upgrades

FPGA for Litecoins is on its way too.

o rly. where from?

No point in buying anything from BFL. There are tens of thousands ahead of you, they have taken pre orders for almost a year. When you get yours the difficulty will be so high it won`t be much profit in it

Well that sucks.....

you can buy a jally today for 308 delivered to all 50 states.

https://products.butterflylabs.com/homepage/5-gh-s-bitcoin-miner.html

274 plus 34 to ship it. may arrive sept. most likely arrive oct. if they ever really do get their act together. so now you have 308 spent and zero hash. I advise everyone to buy it I ordered 2 of them. but right here right now I am mining with a lot of GPUS. So what is your rig ? you may be able to add hash to it if you have an empty slot or 2 inside it.

what mobo? what cards? I tell most people to spilt their risk a gpu setup for now and an asic on order for later. maybe a few shares of asicminer stock. this put you in 3 camps. and you may be able to spend under 1 k to have some of each.

Anyone trying the new drivers, 13.4 WHQL or 13.5 betas?

I've been on 13.5 for about an hour now and haven't noticed any differences from 13.3 beta 3 on my 7950 system. Haven't updated my other machines yet.

Assuming any normal power cost and power consumption, you are losing money to operate that. Power costs might be a little less than $1/day, and revenue is less than $0.60.

Need to go AMD...the grass on this side seems to be covered in these green, rectangular things, made of a paper-like material. Yep...grass is definitely greener on this side.

You using cudaminer, Keys? Maybe double your hashrate...or sell that 660 and get a 7950, hehehe :sneaky:

(edit: btw, cudaminer's for scrypt coins like Litecoin, not bitcoin)

or if he has the right mobo keep the card for gaming and all other uses. then drop a hd7790 in a spare slot. you cam get one for under 1300 after rebates selling the game key. he gets to game when he wants on his nvidia and

he can hash at 300 for only 80 watts on his hd7790 24/7. the card makes almost $1.75 a day after power is it worth it meh who knows.

does it cost a lot no. There was an interesting article about Argentina suffering from Hitler type inflation. (Pre world war II Germany had insane inflation) Many Argentinians are looking toward BIT Coins as a hedge it is easier to move then gold.

This would be yet another reason for bitCoins to be 'Good' vs 'Evil'.

I betcha on day one of the beginning of the bitcoin era, 72 Mhash/s was probably really decent. Now, forget about it. That time is approaching for 7xxx owners to. It will be only ASIC, Avalon, and FPGA's down the road a spell. It's too late to get into bitcoins now with just GPU's and from what I'm reading, you'd have to give a kidney to get ASIC's anytime soon. Something like 10,000 orders need to be filled by butterfly labs alone. As difficulty increases, 500Mhash per GPU isn't going to look so hot either.
I'm not really going to mine or attempt to mine with the 660. I just wanted to see what the hash rate was.

Yup pretty much.

My tip: Follow threads about upcoming FPGA Litecoin miners. Be the first one to preorder them, get on the first batch. Mine mine mine.
That might give you many months to mine Litecoin with FPGA kinda alone with low difficulty. Use those Litecoins, exhange them for Bitcoins if the value of Bitcoins skyrocket due to the high difficulty in that network.

Profit!

There are a few FPGA Litecoin miners out pretty soon We have to see if they are real first though

Won't work. There are a zillion people chomping on the bit to do that exact same thing.
