I was just learning about how you can set up your wallet, and if you lose it, your coins in that wallet are gone for good.

So does that mean a nefarious person could purchase all the bitcoins that exist, and just throw away his wallet, and completely break the whole system?

That's an extreme, but if there are a finite amount of coins, I could see how it might make sense to destroy a portion of the coins, to drive up demand for the remaining coins and therefore come out ahead somehow? But can you really just utterly destroy a coin by putting into a wallet that you delete?

been thinking of trading a lot of my hard mined ltc for btc but my goodness the swings I see in 30 seconds are frightening. I have to think some group is manipulating the prices. I'm all for tech but if this is the real swings of bitcoin I can't imagine the masses uses it.

Yep.

For any merchant who takes it, they'd have to transfer immediatly to dollars because of this. Unfortunately what will drive BTC is merchants taking it,.. a bit of a catch 22 if the price swings continue this violently.

If every merchant who took dollars immediatly traded those dollars out for soemthing else, think of what it would mean for the value of the dollar. Yet we want BTC to be used by merchants....

Immediatly selling BTC for USD isn't a good thing. BTC needs some stability, otherwise the thing needed to drive it's success (purchases/trades in BTC) will drive down it's price.

Miners are big part of the problem as well. Intent was to have an alternative currency, not simply 1's and 0's that get traded into USD and gamed.

That being said, I think BTC comes through it stronger in 12months time. But the swings could easily continue to be 50% in a few months time for the forseeable future.

WMLTC has been f!*&ing up.

They fixed it yesterday. Their servers are back to normal and stable again.

Edit: nevermind, it is f*ing up again...

Not true, you can backup your wallet. As long as you keep your wallet(s) backed up, it would be difficult to lose it along with the coins.

Yes, I agree we should back up our own wallets.

But I'm curious if you can intentionally destroy coins like this, by simply removing them from circulation for ever. There might be a situation where you could buy up a lot of coins, and then destroy a portion of them to artificially inflate the value of your remaining coins. But then those destroyed coins would be gone for good?

What does "Forked" mean?

One blockchain differs from another blockchain on the same network for whatever reason, be it a 51% issue or deliberate codebase fork issue.

It means from a given block onward, the blocks that one branch (fork) of the network processes will be completely different and incompatible from the other branch (fork). Any coins/transactions/blocks on the "smaller" fork basically are meaningless to the network as a whole, and will essentially be discarded.

Simply put, if you have coins in your wallet, make sure your wallet is up to date before you go sending them anywhere. It's also a good thing to make sure any exchanges you deal with also are up to date - which is how I lost $100 worth of altcoins that I will more than likely never see again.

This makes no sense. It's all supply and demand. If you simply hold onto the coins that would have the same effect. Why would you destroy the thing that holds the value? In theory this would drive price up per coin, but it wouldn't change the total market cap.

Apparently a guy in Britain discarded a HDD with 7500 BTC on it:

Hard to believe, honestly. But maybe it's true. I know I have never discarded a HDD unless it was completely broken. Even then I have usually taken them apart. I have sold a few extras/backups, but I mostly keep HDD's that I've actually used in my personal machines; I have around 20 HDD's in a box in my closet, dating back to 1999 when I bought my first laptop.

Crashing again... if LTC falls to $15 or BTC falls to $500 and looks to be bottoming out I'm going to buy in. Silverforce may be right... it's probably a good bet to just sit on the coins. BTC could definitely go well over $1000 and be stable well above that. $10000 a piece even. At that point LTC would skyrocket even more exponentially.

Currently: BTC@$762, LTC@$21.9.

Crash appears to have been triggered by taobao.com (basically chinese ebay/craigslist) banning anything bitcoin/cryptocurrency related.

Early reports are that the following are examples of banned items:
1. Cryptocurrency units
2. Software and hardware for the mining of cryptocurrencies
3. Tutorials and consultancy services
4. Any other item intended for use in the mining or distribution of cryptocurrencies.

I just installed my 2nd 270 and am dealing with heat issues (side panel off with fan on it for now) in my crampt coolermaster storm scout mid tower case. When I make enough profit (so wife doesn't complain) I was thinking of getting a bigger case for better airflow. What cases do you guys use? I do have milk crates but I really don't want to go that route.

What does "Forked" mean?

It means that the blockchain has split, with different copies of one or more blocks in different parts of the network.

Blocks are created by mining - the miners compile a list of transactions and then sign them off, with a "proof of work" (effectively a lottery where there miner computes a hash to see if it gives a specific answer). The list of transactions and its signature become the next block in the blockchain.

Under normal circumstances, two separate miners can find a new block simultaneously (or nearly simultaneously) by chance. The result is that the blockchain has split from a single trunk to two paths (hence the name, fork). Under normal circumstances, one of the branches (and the transactions in it) will be cancelled automatically. Effectively, the network will cancel the shorter branch.

Usually the forks only last for about 1 or 2 blocks, before the network detects them and cancels the shorter branch. However, if there is a major network disruption - e.g. if Europe were to get disconnected from the US, then there could be a major temporary fork with different block chains developing in each separate network. When the networks eventually rejoined, the longer chain would win and the shorter one would be rolled back. A similar effect can occur if a miner with massive computing power but a slow (or deliberately manipulated connection to the rest of the network) starts mining a coin. This is sometimes called a 51% attack, because it can be used to reverse a payment some time after you made it.

This type of fork is sometimes called a "soft" fork, as it will eventually reset itself (but it may take a long time, which can result in thousands of reversed or lost transactions across the network).

The other type of fork is a "hard" fork. If there are 2 versions of the client sofware on the network, they may disagree about what is a valid transaction. Some clients might reject a transaction, but some might accept it. In which case, the block chain will fork with some mining a block with transaction X, but other miners mining the same block without transaction X. In this case, because the clients cannot accept the other client versions blocks, the network will not autocorrect. This results in effectively two different sets of wallets depending on the software you are running. When this has happened, it usually needs an emergency patch to the defective software version, and emergency software updates by all miners and currency users.

Looks like Ron Paul coin difficulty is about to more than DOUBLE, unless of course the massive increase in network hash rate was due to one of those multi pools pointing their miners to RPC coin, skewing the estimated next difficulty.

Yes, you could simply set up another wallet on another computer or virtual machine, send some Bitcoins there, and then nuke it from existence.

Might be possible for a virus to screw up the wallet. If the data was lost and not backed up, the coins are indeed gone. This unlike even hard currency, in which they can still debase the currency.

Or if the data is online, a catastrophic hardware failure or the hosting provider going belly up...

you lose more than you gain, unless you own 100% of coin in which your loss is equal to your gain.
Destroying currency in such a way is not a plausible attack, the same way that nobody worries about people buying gold only to throw it down an active volcano.

Besides that, bitcoin can be divided into very small chunks and if needed that divisibility can be extended

Welcome to the world of 2+2=3.5.

The top card will run a lot hotter. You can play with various fan setups, get a bigger case with more fans, or try watercooling. I finally received my copper shims so my AIO cooler is going on one of my 7950's very soon. Google the "red mod."

So that means if someone pays me in Bitcoins and it gets reversed due to a soft fork I am SOL?

very happy with the Corsair 540. If you want to go cheap look at test benches from DIY at the Egg. They for as low as $50

Just cashed out my first chunk 'o BTC with Coinbase. Looking forward to being one of those that complain about the flagged accounts etc in a couple days.

That said, my first month or two of mining will go toward paying for mining gear and bills, then I'll start stashing away some coins for "future use".
