Bitcoin Thefts Surge, DDoS Hackers Take Millions 305
CowboyRobot writes "In November, Denmark-based Bitcoin Internet Payment System suffered a DDoS attack. Unfortunately for users of the company's free online wallets for storing bitcoins, the DDoS attack was merely a smokescreen for a digital heist that quickly drained numerous wallets, netting the attackers a reported 1,295 bitcoins — worth nearly $1 million — and leaving wallet users with little chance that they'd ever see their money again. Given the potential spoils from a successful online heist, related attacks are becoming more common. But not all bitcoin heists have been executed via hack attacks or malware. For example, a China-based bitcoin exchange called GBL launched in May. Almost 1,000 people used the service to deposit bitcoins worth about $4.1 million. But the exchange was revealed to be an elaborate scam after whoever launched the site shut it down on October 26 and absconded with the funds. The warnings are all the same: 'Don't trust any online wallet', 'Find alternative storage solutions as soon as possible', and 'You don't have to keep your Bitcoins online with someone else. You can store your Bitcoins yourself, encrypted and offline.'"

It seems pretty simple on the surface but it's actually not. The point that the GP post was trying to make is that in a small or illiquid market, large sales volumes can actually depress prices by introducing too much inventory to sell vs. people willing to buy. This is a somewhat different example, but back in the day when Bill Gates still had a meaningful percentage of all Microsoft's shares, he would be said in the media to be worth "[his share total] x [current MSFT quote]." But people who knew the market actually understood that if he ever decided to liquidate his shares all at once they would be worth far less because he would actually flood the market (leaving aside the fact that if people figured out that Bill Gates was selling all his MSFT shares, they would flee the stock in droves assuming he knew something they didn't.)
So long story short - if I have a trivial number of [shares, rare items, whatever] compared to the market size, then, yes, they are worth [quantity] x [going price]. But if I have a quantity that is significant to the size of the ability to make markets and I try to sell it all at once, it will invariably be worth far less.

key pairs in a wallet can also be generated using passphrases (so called brain wallet).
in theory the owner is the only one to know the passphrases generating the key pair and thus the only one able to use the private key.

In the UK you can save with the government and cut out the middle man. The UK government owns a bank named the National Savings Bank (actually they own several banks, but this is the only one that offers savings accounts to regular people) which offers a middling interest rate and various long-term bonds. When you "invest" in the government's bank instead of it lending the money to somebody else like a regular bank it just spends it on government projects. The money to pay you back later comes from taxation. So in effect it allows the government to borrow from the ordinary consumer at a better rate than they'd get from a foreign bank, and it lets the consumer save with a 100% trustworthy bank.
Anyway, for long term savings the National Savings Bank will give you points over inflation. They will promise to track better than the rate of inflation in interest. They can do this because they are, after all, the government, if they can't make it worthwhile to borrow money at points over inflation they definitely shouldn't be borrowing from foreign banks! Of course "worthwhile" gets to be over a long view when you're a government. Money spent today ensuring a five year old is healthy and well educated pays off twenty, forty, sixty years down the line.

This is the attitude of someone who is poor or broke.
No, that is the attitude of people who are rich. Someone who is financially successful doesn't have time to learn an entire professional level skillset just to do simple financial transactions, especially when there are much better and easier alternatives.
If you are investing your hard earned savings it is prudent.
Investing? Is Bitcoin a currency or an investment vehicle? Currencies aren't investments or investment vehicles, they are mediums of exchange. One can make money currency trading but that is not investing, it is speculating on a change in value in the sho

So if you had any cash in your wallet, that would be gone and you could NOT replace it, much like bitcoins.

This is one of many reasons why nearly everyone pays with plastic. Cash is used only if you have no bank account. I keep very little cash, never carry it, and only use it for transactions at a flea market, for example.
Not only using plastic is free and safe; it is also profitable (to you) because the bank shares with you a small part of the 2% that the c/c networks charge for transactions. The ven

This is not something I can change. These 2% are a business agreement between the merchant and the payment network. The merchant is allowed by the contract (or was allowed, at least) to offer cash discounts. But rare a vendor does that. Some gas stations are the only example I can think of.
So, here we are. The 2% are built into the fabric of the entire economy. It does not matter if I pay with plastic or cash. What do you propose, outside of marching with torches and pitchforks toward the VISA HQ?

In fact, why in all hells would you even think of storing your wallet with someone else??? I'm fairly new to bitcoin, but the thought was so far from my mind that it took me a while to understand what the problem with these kinds of attacks was.
Don't people get it that Bitcoin is money? Storing your wallet on someone elses server is like giving them your money. You do that with a bank, but not with some random Internet site.

Both are equally "real", a "wallet" file doesn't store bitcoins as such, it stores the keys which allow transfer of those bitcoins.
If someone hacked into your system and made an unencrypted copy* of your "wallet" file then they could use the keys in that file to transfer the money to addresses they control. Once they do that you will no longer have access to the coins. On the other hand if they just made a copy and didn't do anything with it (unlikely) then you wouldn't notice anything at all.

Surprised NO ONE is mentioning this....
Sheep Marketplace went down yesterday after weeks of suspicious behavior such as disabling withdrawals of money, a countdown to when withdrawals would be available but running at a slower speed, still no withdrawal when it expired, minimum of 1BTC withdrawal so people would deposit money, and more.
So far it appears some $47 million worth of bitcoins was stolen.

I don't have a better word than "proxy", but here is how it works:
You have two accounts registered in the software, your exchange account, and your wallet (the one that is all yours on your local machine).
When you receive funds in your exchange account not from your wallet, it immediately shuffles it to your wallet.

That depends on what the person who got illicit control of the BTC does.
What do you suppose occurs, if the "thief" doesn't spend their illicit booty? Perhaps they have their lawyer figure out the statute of limitations for any potential crime they might get charged with, and plan their BTC transactions to occur, after that all runs out.
