Topic: Where and what did you just buy with your Bitcoins? (Read 2244 times)

Pizza, I buy a lot of pizza with my coins. In keeping with tradition of course.

I've paid for a beer.

bought window 7 key and steam gift card on this forum using my bitcoins

Hookers, blow and ak47s from silkroad. I trust them with my data 100%.

Paid for a years subscription for my VPN and had a delicious indian takeaway last night, all courtesy of btc  

Blockchain.info is a hybrid wallet.

As long as you don't have any malware running on your system and you use a strong enough password, blockchain.info doesn't have access to your private keys or your password.

With blockchain.info you have exclusive control of your private keys.  This is the important point in keeping your bitcoins safe.  If you don't have exclusive control of the private keys, then you don't really have any bitcoins.  If you do have exclusive control, then you are completely responsible for keeping that access secure and for backing up that data to prevent loss.

Lets consider the following imaginary scenario:

• You install Bitcoin Core
• You create your wallet
• You encrypt the wallet.dat file with a strong password
• You store your encypted wallet.dat file on some "cloud drive" (dropbox, google drive, icloud, whatever)
• You delete Bitcoin Core from your computer

Now you have your private keys securely encrypted and stored "online".

Any time you want to access your bitcoins on any computer, you can just:

• Download Bitcoin Core onto that computer
• Wait for it to sync with the blockchain
• Download your encrypted wallet from the online storage
• Decrypt the wallet.dat locally with your password
• Install your wallet.dat in the Bitcoin Core that you just downloaded
• Use Bitcoin Core to send and receive bitcoins
• When you are done, re-encrypt your wallet.dat
• Replace the online storage of your wallet.dat with the updated one
• Delete Bitcoin Core from the computer you are using

And there you have it, Bitcoin Core IS an online wallet (as long as you download a new copy every time you use it and you store your wallet.dat encrypted online).

This is essentially what blockchain.info is doing.

When you go to their website, you download wallet software into your browser which runs locally on your computer (much like downloading Bitcoin Core every time you want to use it in my imaginary example). Then you download a copy of your private keys that blockchain.info stores for you in encrypted form.

When you type your password, it is not sent to blockchain.info.  Instead it is used locally by the software that was downloaded from the website to decrypt your private keys in your computer.  If you add any new addresses, they are encrypted locally on your computer with the same password and then sent (in encrypted form) to blockchain.info to be stored for you.

When you send a transaction, blockchain.info sends the information about the unspent outputs down to your browser, and the software running on your computer creates and signs the transaction locally on your computer.

The main risk that you take, (other than malware running on your computer) is that blockchain.info could lie to you about the unspent outputs in your wallet.  In other words, they could fool you into believing that you received bitcoins from them (or from people that they are colluding with) that they never really sent.  They can do this because the software that is running in your browser gets its list of unspent outputs from them without verifying the validity through the entire blockchain.  Of course, a quick check with other trusted block explorers whenever accepting bitcoins is an easy way to make sure that they haven't done that.

I didn't think you'd be a fan of blockchain.info or any online wallets. I use blockchain.info for my 'current' account and for daily purchases etc as well. Hasn't failed me yet.

I bought some DVD's from overstock.  Was a good way to watch some cheap TV/Movies for a small part of my coins!

Not sure if it counts but I bought some coins using an Exchange
Pondering whether to buy something on newegg since they have a deal with Bitcoins going on though
Non-Refundable though but it does seem like a good time to get a discount on an Xbox perhaps.

I bought a book on amazon.

Exchange to Rupiah few days ago and buy some gigs on http://fiverr.com

Bought one of these...

I went to newegg and bought something...you all know about

Playstation

Works well and good.

Bought my first miner to get my feet wet.  Now that it's churning out .0071 bitcoin a month, I think I'll buy some more bitcoin and get a larger miner.

I carry a blockchain.info wallet on my smartphone with small amounts for payments when an opportunity presents itself.

It was VERY easy.

• Logged into my account at www.dish.com
• Clicked the "Pay My Bill" link
• Chose the "Current Balance" radio button, and clicked the "Continue" button
• Chose the "Bitcoin" radio button, and clicked the "Continue" button
• Scanned the presented coinbase payment QR-Code with my blockchain.info wallet
• Clicked the "Send Payment" button in my blockchain.info wallet

That's it.  Account at Dish was instantly updated with the payment.

Bought an uzi and drugs.

also cool 

easy?

What I would eventually like to do is pay off all my loans with Bitcoins....Living debt free would be so nice!

Let me see :
- $20 Steam Wallet
- some Original games
Now, with bitcoin i already have 40 original game (most games from big publisher)

Maybe some electronic items if i have more BTC

Paid this month's Dish Network bill.
