I was wondering if anyone here is using Bitcoin?

not using it but listened to a very interesting podcast by Steve Gibson explaining it all a few weeks ago now. Podcast is called Security Now if anyone is interested and is usually very good. He even managed to get himself 50 bitcoins by finding one of the numbers with the leading zeros that you can set your pc to search for to earn bitcoins.

I've been using it. I have a small amount, used the various exchanges, and stay up to date with the goings on in the community.

I've mined 120 btc so far, sold my first 50btc for NZD $75, my second 50btc for NZD $200.

 

I've spent $1764 on my mining rig, which runs at around 1200 MHash/second. I get around 8-10 btc / day now. However that should decrease in about 6 days time when the difficulty increases.

 

I expect to pay off my kit within 60 days.

I dont get it, sounds like it installs a client on your pc to do what? Steal your data? Backdoor to operate a DDoS attack? All sounds a bit fake to me :)

No, it's an alternative currency using cryptographic principles to handle generation and spending. See http://www.weusecoins.com/

Heh, I've been watching this for about a year or so and becoming more and more depressed. I had an opportunity to invest way back then but i procrastinated on it Tongue out.

If anyone wants to trade 10 or so coins, pm me and I can wire you the money or something.

I've been using it for 3 weeks, built a mining setup consisting of 8x graphics cards, nets about 12 bitcoins per day at current difficulty.

Do you accept BTC for subscriptions? Tongue out

But what does the mining setup actually do? Aside from generate bitcoins.

Does it calculate anything of actual use? Like the ps3 folding@home project? Or does it simply calculate stuff for the purpose of generating bitcoins?

It calculates stuff for the purpose of generating bitcoins. Each miner gets given a block of data and must perform a cryptographic hash of this plus data the miner comes up with (called a nonce). If the hash of this combined data is less than a target value, decided by the network, then the miner 'wins' and a block is generated. The block contains the new 50 bitcoins and any transaction fees attached to the transactions included in the block.

So a miner basically takes this data adds a nonce, hashes it and compares it to the target. If it fails then it comes up with a new nonce (it's usually an incrementing integer number), re-hashes it and compares again. It repeats this until successful or given a new block of data, You can see how this can be paralleized (run hashes with different nonces on each CPU) and why GPU's are useful for the process.

If you have bitcoins you will need the id for the payee, and you then start a transaction to the id...
