Happened to me once or twice.
This is related to the time correction. If your device and the site has a time lag, you would miss the correct code by few seconds.

To rectify, go to your GA app settings and you should see an option for 'time correction'. Tap it and select 'Sync now'.
Once it is synced, you should be able to use the app just fine.

You just have to click a button to create a new address. You all previous addresses are kept intact in your wallet program, so they're not lost. Any future Bitcoins you receive to your 'old' address are received just fine.



All wallet programs can hold several hundred of addresses, or more.

Bitcoins don't grow themselves. Just like any other form of money, you need to take wise decisions and invest carefully to make them grow.
Many people day-trade Bitcoins to make profit from price volatility. Some people also trade Bitcoins for promising alt-coins and then sell when alt-coin price increases.

But trading is only for people who know what they're doing and are ready to lose their Bitcoins if market goes the other way.
If you're not sure what all this means, you better just hold on to your Bitcoins for a prolonged time and see if it rises in price dramatically.

Yes, Bitcoin price is volatile. So if you have 1 Bitcoin, you will always have 1 Bitcoin, but its value in USD (or any other fiat currency) can change dramatically over time, either way.

OK, I didn't know that Armory needs QT wallet to function.

So Armory is not a 'light' wallet, then? I currently use Multibit and was thinking of trying out another 'light' wallet. What are my options? Electrum?

I also have my cold wallet stored on a USB flash drive and this thread gives me shivers.

@OP, did you ever solve this problem?
If yes, what steps you took?

I would now consider putting double-encrypted copy of my cold wallet in some kind of cloud storage also.

Not sure what you mean. You're talking about two different wallet programs here. One is Bitcoin Core-QT and the other one is Armory.

Are you saying you can get the QT wallet to sync but Armory doesn't sync?

Last time I checked, Bitstamp was charging $15 flat for wire transfer, regardless of the amount you send.
They have recently changes their fees structure and have lowered the trading fees. Not sure about deposit fees.

30 Euro is very high.

if you are taking enough careful steps to keep your coins secure, any OS is good. if you are not careful, no OS is good.

Learn about cold storage and offline wallets to protect your Bitcoins. Live Ubuntu CD  can help in creating a cold storage without formatting your hard drive.

Welcome to the Bitcoiners club!

I understand your pain and frustration. I was in the same boat once because I live outside USA and there were no exchanges in my country.

However I found Bitstamp which accepts wire transfer from international bank accounts. it takes few days to get funds in your Bitstamp account but at least it works.

Thank you for your help and others'.

I have updated my signature to reflect Hero status. Let's see if the bot detectes it.

Marco,

I re-enrolled with the bot today as Senior Member. And just after a couple hours after registering, my account became Hero Member.
I haven't made any posts yet after registration. Is it possible to upgrade my registration from Senior to Hero?

If not, then also its OK, I have been with this campaign for over 2 months and will continue.

Thanks!

So..  what happened to this service?

Just when I thought I was going to purchase a VIP account, the service went offline.
Looks like the domain expired and hasn't been renewed for a week now:

A bitcoin address is not enough to recover your Bitcins. What you have is your public address. You need the private keys, which you don't have.

In that case you have to get your "wallet.dat" file back.
MultiBit stores it in "C:\Users\Username\App Data\Roaming\Multibit"
Try to use a recovery software and see if you can get this file back.

Payment received; thanks Bit-X for the awesome campaign!

Looking to continue for the next month.

But it takes 15 CONSECUTIVE successful trades in order for this to work.

And it takes ONLY one unsuccessful trade to lose everything.

Yup.
It was $90 to $1100 for me.

I read about Bitcoin in some article online, looked at the price and it was $90. I transferred $180 to BitStamp to buy 2 Bitcoins. The price kept increasing steadily and I waited for it to come down to $90 again so that I could buy 2 BTC. And it went all up to $1100.

"The Bitcoin Ninja" almost killed me.

I hope you're feeling good now.

First of all, understand that there is almost no chance you'll get your BTC back.

Second, post some proof and info about the scammer so that everyone else can keep away from him and give him negative trust (This isn't much helpful since 2.18 BTC is a good amoun to abandon an account completely. The scammer will usually start a new account to continue scamming others.)

Third: Use escrow next time.
