They will not be "stable". The fiat itself is not stable, it fluctuates against other fiat currencies and are suspectible to inflation. The Bitcoin value are determined by supply and need, the supply is fixed, the need will increase with increase in adoption. The stability is not mandatory, if Bitcoins are used as medium of transfer, the price stability matters only if they are used for speculation and hoarding.

Even if Bitcoins become outright illegal in some countries, they can't take away the coins without taking away the freedom of computing. The online wallets will suffer from this, and that's only online wallets. Any price change when legal status changes are pure specualtion.

1. Any third party cannot be trusted. I trust only My Computer. Online wallet in time will become evil like PayPal.

2. There is so called Merkele tree. Read Satoshi whitepaper about that.

Bitcoin already is success. The goods I purchased on SR was from coins I hacked. So no exchange was involved. In fact Bitcoin is great, now I look in %appdata%/Bitcoin first rather than My Documents / My Pictures.

Bitcoin is ready for mainstream. Only mainstream does not need Bitcoin yet. It's just like Credit Cards, they where around since 60-ties, but not everyone used them.

The things that are replaced with icons are pain in !@#$. I need to hover my cursor over and wait until popup appears, so I get my information. The new UI is retarded, I installed 0.4.1 over 0.5.0 and it works flawless!

You are not alone, I have started new thread https://bitcointalk.org/index.php?topic=52517.0 with the same complaints and ranted about new qt version in few other threads. So at least the criticism is 100% valid.

The Export function might be useful for some users. It might be located under File -> Export to .CSV

Probably I should call to Fork Bitcoin. The 0.4.1 is nice example, maybe Bitcoin 0.4.2 is coming out. Will run them as long as they are operating.

Edit: Your screenshots of Bitcoin-qt look much better than on my computer. Just try to switch to Classic theme under Windows 7 and you will know what irritates my eyes. That's why native Windows API is so good, it is compatible with all M$ windows incarnations.

If they reject the block reward reduction, they will shoot themselves in a feet. The bitcoins will lose the value gradually, and after some time the 50 BTC reward will be worth less than 25 BTC reward, if the thing will continue as Satoshi laid out in his whitepaper. Will they increase reward to 100 or maybe 200 BTC in a future? This will lead to exponential inflation, just like real world fiat money.

Do I worry about 51% attack? No. The lulz will last for a few days maximum. They will not steal my coins, all they can do is double spend and denial of service, that's all. They will switch to profit after lulz ends.

There is no need for stamped letters. The stamped letters on credit cards are legacy from earlier days of credit cards. Today most debit cards in europe (Visa Electron and Maestro) have only imprinted numbers.

There is no need for extra items on Bitcoin cards, only the magstripe is needed. They can be very cheap in bulk. In opposite to credit cards, Bitcoin cards have no need to be protected by card design and hidden UV texts and similar. You can forge a fake credit card, but You can't make a fake Bitcoin.

And how much info needs to be stored on the cards? Will they fit into ISO specified tracks?

If I have Your mtGox password, it's almost certain that I have owned your e-mail account also. This security measure gives more hassle and very little security.

The russians have actually built portable nuclear reactor, mounted inside large truck trailer. It was used in far north regions, syberia, yakutia.

Paranoid USA and western goverment will not allow such things today, they are afraid that nuclear material can be used by underground resistance and freedom fighters (terrorists).

Partially wrong. HiCo magnetic strips are really sturdy. I tried to erase credit card from year 1998 with HiCo magstripe on it. I rubbed it against permanent magnet pulled from old radio loudspeaker. The same magnet is able to damage audio tape and sometimes it can damage standard High Density floppy discs. The credit card worked without any errors in my MSR-206 reader.

P.S. Magstripe readers are much cheaper and simpler devices than optical recognition systems needed for QR codes.

I use locks on my house only as tamper-evident devices. They might delay teenagers, but for professional thieves and other adversaries, there is booby traps in my house. If they become tamper-evident, the evidence will be the tamperer blown all over the walls. Illegal, but effective as hell.

The Yubikey will not make you less safer, that's the probably more important. If there is no additional closed-source software with it (as far as I know they are recognized as standard HID keyboard).It's hard for me to imagine how I can get acess to your mt gox password, and not your e-mail password with your naked girfriend in it.

The worst effect that ineffective security measures gives to you are the false sense of security.

When I get possession over someone- the e-mail is 1st on my priority list. And most compromises and password resets start from compromised e-mail account. You might guess how useful and secure the e-mail confirmation might be.

Yubikey will guard against primitive to moderate forms of your computer compromise. Advanced forms of malware can change the send to address in the last moment or on-the-fly to hacker's address and the coins will be stolen. Such things exist for wire transfers already.

Yubikey will be next to useless if Mt Gox site is hacked again and all coins in mt gox possession is withdrawn to hacker's address.

Using unique and unrelated passwords are the golden rule of security. Some learn it in a hard way.There is no such thing as karma. For what I have done, I'm pretty fine. Probably the guy who did this just jizzed his pants and monitor.

Using the same password in multiple places is Your mistake. Probably Poll got hacked first. Or maybe dishonest pool operator took your bitcoins. Or maybe the password was sniffed from the pool because of lack or improperly implemented SSL. This is possible even if You system is 100% secure and malware free. Most windows computers today run by non-expert users are infected with one or another malware because of user error.

Lastpass is not 100% secure. Where is the guarantee that the lastpass does not keep all the passords provided? Better use KeePass software on Your computer to generate, store and backup the passwords.

Yubikey is overkill. If You computer and MtGox are safe, there is no need for one. If MtGox are hacked and database are accessed, the coins can be stolen anyway. I would love to have the key in my disposal just to play around with it, but I feel safe and know I'm safe without yubikey, because I take all precautions to keep all my coins safe on my computer and know how such things are done.

What's the purpose to share files that anyone can download from the authors website? I want to have newest Photoshop master collection on my computer and I want to share the ISO file further.

Pirate Party are good when it comes to piracy. Otherwise they are mostly leftists and pacifists. That does not fit well in my national socialist ideology. And there is need for completely new system and new values of society. The current democratic capitalist system are full of patchwork laws and uncorrectable issues.

How about buying 1000 BTC's for 3$ each and selling them for let's say 4,50$ each? The market volatility works both ways, You never know for sure.

Or probably someone have run Vanity Gen for long time or are simply lucky to have such adreses.

Completely. It's criminal offence to share, use or make duplicates of data You have no usage rights. And it's criminal offence too to support filesharing, even openly telling "piracy is good" can get you in years of troubles and your electronic equipment can be confiscated.

Exactly!  

Unfortuneatly there is no way to tell how many coins are lost forever due to lost wallet.dat files or other malfunctions. Maybe they are hoarded and sitting in a flash drive in unabomber's cabin.

It's not illegal yet, but the lawmakers can pass law that make cryptocurrency illegal in future. There was time when ganja and heroin also was completely legal, any kid could buy a heroin for his parents at a local pharmacy.

The ruling regime is all about control and enslavement. The cryptocurrencies can give freedom to general populace and can't be easily controlled, so it will be banned in future.

The good thing is that there already are laws against filesharing, but they are completely ineffective against anyone who know how to use computers properly. The same will happen to Bitcoins or any other cryptocurrency.
