Cryptsy is so slow at the moment, it's taken me over 2 hours to complete just a few trades...

Electricity at 5 cents ker kwh is quite cheap and you can probably be profitable at that rate.
In regards to temperatures, from November to February, you look to be fine. A few rigs will even keep your home warm during the colder months...just have a couple fans moving air away from the rigs. In the summer, when temperatures in your house get above 25 degrees C, you're probably going to want to clock down your GPU's or run an air conditioner.
Keep in mind that some cards run cooler than others, even cards of the same make and model. I ordered 30 5870's last year. At 100% the cards ranged from 54 degrees to 120+ degrees with ambient temperature of around 20. I returned 15 of the cards that ran above 80 degrees and only kept the cool ones. Then again, I ordered these cards directly from a factory here in China and quality control is not a concept that the Chinese quite understand yet. Hardware is cheap, but close enough usually cuts it here.
Also, back when I first started mining, it took a lot of tweaking over several weeks to get the systems stable and be confident that they will mine 24/7. I'd often wake up to find several rigs crashed over night, sometimes from silly oversights but other times for no apparent reason. Eventually you iron these small issues out, but still today a system might halt after a few days and I still don't know why. Some people have scheduled in automatic restarts every x hours for this reason.

How much do you pay for electricity in India? What's the average temperature in the room where you'll be operating your rigs? You will not be able to run your cards at 100% if you can't keep the room cool and the air flowing.

No. So far no ASIC has been developed for Scrypt.

I've downloaded the latest client v0.8.4.1-6-g00736fb-beta but its not connecting to any peers. Even after 12 hours it just says I'm 21 weeks behind and no block source available. I don't have this issue with any other clients so I don't believe it has anything to do with my firewall or port forwarding.
Anyone have any active nodes I could add to my config file to see if that might solve the issue?

The number of connections will have no impact. The only time it might help is when the difficulty is very low and you're racing to submit blocks.

Maybe you guys can take a look a t cosmoscoin. CMC has the following features: - Proof of work/proof of stake (Resistence to 51% attack) - modified Scrypt algorithm - Transacation Comment like FlorinCoin - 0 transaction fee - 60 seconds block time - 3.5 coins per block - Day generation: 5040 coins or 1440 blocks - diff re-target every block - Trade confirm: 3 - Mine confirm: 30 - fair start, no premine - port: Connection: 19990 and RPC Port:19991 The ANN thread of CMC is : https://bitcointalk.org/index.php?topic=245938.0 , you can find more info about CMC and discuss some topics you interested in there. Not nice to hijack the thread mate. See how Terracoin failed then take a look at your own coin.

Too bad google translate does such a poor job with Chinese. Good post though. It's refreshing to read something which serves up the reality to late comers, instead of this 'In 50 years time we will all be millionaires' bullshit.
i like how you (2 1/2 months registered here) consider yourself early comer. Every late comer (including myself) must do their research on their own to learn the history of digital currency, and dont expect from "some" guy to tell his opinion about it. He doesn't say he was an early adopter...in fact I gathered the opposite from his post. And yes, it's good for late adopters to know these facts.

3. My house has a electricity back-up system, just like many other houses in London.
So how is this relevant then? Go back to reprogramming your Avalon chips to mine Litecoin. While you're at it, I've got an old microwave you can reprogram into a Scrypt ASIC as well.

Firstly, electricity is not free. Someone is paying for it. You are essentially trying to sell stolen goods.
Residential properties in London typically have only a 60 amp service, unless you are in a very new house, then you might have 100 amps. 100 amps at 220v allows only 22,000w.
So you also bought a 250,000w backup electrical system? Lol
You're full of shit.

250,000 watts of free electricity in your house in London that also has free backup electricity in some form?

Can you elaborate a little more on exactly how and what you're testing here?
I am experimenting with reorganizing past blocks in a chain. I've noticed that the time it takes for my chain to be accepted by the network increases with the number of blocks I try to reorganize. Obviously I'm testing this on a private chain of which I'm connected to 3-4 peers out of a total of about 10 peers on the network. I have ~70% of the network hash rate.

I want to buy DBLs at $2/DBL. PM me.
First come first served.
How many do you want to buy? What is your payment method?

The client will continue to work as normal, so you can choose to ignore the message. Whether you want to invest time in a coin that the developer has neglected is your choice.

Can someone please explain to me the differences between scrypt mining and SHA-256 Mining Different algorithms.

I was just reading up on bitcoin in Iran and I saw that sourceforge censors downloads from IP addresses in Iran. Iran is experiencing severe inflation right now and bitcoin might really be able to help some people. I don't know who is responsible for the sourceforge bitcoin account, but I just want to make sure that the settings are set to allow downloads from "axis of evil" countries where good people might be the victims of bad governments. http://www.forbes.com/sites/jonmatonis/2012/10/09/as-inflation-rages-in-iran-bitcoin-software-not-available/ I didn't find this topic already addressed in a search, so I thought I'd mention it, since inflation in Iran doesn't appear to be diminishing. Careful. Jgarzik might attack you for even thinking about revealing sha256 to Iran! jgarzik goes berzerk in #bitcoin-dev, wtf? https://bitcointalk.org/index.php?topic=128532.0

Interesting. This makes sense but I'm assuming there's a little more to it.
I believe this implies that the peer does not calculate the sum of all difficulties of the new chain until it has downloaded it completely? Although not very efficient, I imagine a malicious user could take down peers this way.

When broadcasting a new chain to the network that would reorganize perhaps only the 10 last blocks, the network accepts it within the next 1-2 next blocks.
However, when I broadcast a chain that reorganizes the last 300 or so blocks, it takes significantly longer for the network to finally accept this chain.
Why does it take longer when reorganizing a larger number of blocks?

LTC is looking very strong right now. Holding its USD value as BTC falls.
Bitcoin is falling because companies are cashing out large amounts of invested BTC to USD produce tangible products, i.e. ASIC. LTC is holding value the same way my monopoly money is holding value, no one cares what it is worth unless you are in the game. Can you state your source? Which companies are cashing out? Also, I imagine that those that aren't involved in some way with Bitcoin don't really care what it's worth either.

From my understanding, even if you do have 51% of the hashing power, modifying the source code to change the block rate, reward, or difficulty, will have no effect. Are there any parameters that an attacker with 51% of the hashing power could potentially modify in the source code to gain some kind of advantage or cause damage to the network?
