PPC can be somewhat annoying due to the large number of confirmations it takes, but I see it as being more beneficial than TRC and FRC due to the proof of stake implementation.

"It crashed" could mean a million things.  Do you have more specific details?

The 'unique data' is the private key for the address.  When a client generates a new address, it first chooses a random 256-bit number (the private key), and then calculates the public key, which is the address that is used when sending or receiving funds.  Only the person who has the private key which corresponds to the address will be able to spend with it.

The Bitcoin-qt downloads the entire blockchain because it also acts as a node, passing information around and confirming transactions for the entire network.  Multibit doesn't do this and only processes information that is relevant to one of your addresses.

On first run, Multibit will generate a new address that is entirely localized on your computer.  If you decide not to have it encrypt your addresses, you'll still be the only one capable of using it, but there's a higher probability of it being stolen at some point.

Bitcoin-qt downloads the entire blockchain (currently about 9.5 gb) whereas Multibit does not.

Sounds like a decent idea, but I'm not sure an IRS agent would feel the same way if you happen to get audited.

No transactions take place and no accounts are created on that site, so perhaps they don't feel it's necessary to pay for an ssl certificate.

While some would argue that Nvidia is by far the superior brand of gaming gpus, I've only owned AMD products and have been quite satisfied with both their gaming performance and their increased mining ability over Nvidia.

As for workers, it really is that simple.  Just use a different worker on the same account for each machine you're mining on, and they'll all go to the same wallet when you finish shares.

If you want to mine bitcoins, the only way to make it economical is to buy ASICs.  However, if you want to mine alt coins, a GPU rig is a good choice.

CPUs are not economical in the least anymore and will always fall short of the performance of ASICs or GPUs.

Yea but good luck getting it from them this year.

You're better off buying an Asicminer blade or a KnC product.

It's really quite random and there's no way to know for sure.

It won't confirm until the next block is solved.

Welcome aboard!

The difficulty is WAY off on that calculator.

At this point in the game, you're never going to make your money back if you pay for the electricity.

Odds are you weren't able to find a block by yourself, and thus didn't get a payout.

All coins have the potential for checkpoints, it's been in the bitcoin source for ages.  So yes, it's essentially a LTC clone with 4 times as many coins.

I've written backends using the BlockChain api and it's quite simple and has good documentation.

and then the
