Dude ASIC has already occured, GPU mining will be obsolete in a few weeks if not days. (depends on the price action)
Though if you have free/cheap electricity, then you can probably keep on mining for a while. The 5870 is great for mining Litecoin though.

But ebay+paypal fees will cost you about $10 per card. So you actually sold them for $80 each. |

Can you upload picture of all your equipment to see exactly what type they are and also to confirm you have them. Also 2B for 5830 is a bit expensive I believe.

For regular clients, we don't really have to store old transactions, who really care about a transaction happened 5 years ago? for those who care, you can have the option of storing the
full chain. For the rest of us, we'll just store recent transactions. So for example, on installation of the client, you can have the option of:
* store recent transactions
* store full chain
For those who want to look up a transaction 10 years ago, blockchain.info or blockexplorer.com etc... can provide that service by storing the full chain.

OK, I agree here. But it wouldn't happen from one moment to the next like OP described due to No in order to raise the Block limit, pools would need to change their version, too.
They tend to not upgrade until a new version is considered save.
And I agree here. This is part of the reason that Satoshi suggested that the increase in blocksize be scheduled far in advance of necessity. Schedule a blocksize increase in the next release of the reference client that takes effect with block 420,000 (the next halving four years from now). By the time the increase is triggered, almost everybody is running software that was created in the past four years. I don't think anybody who understands the issue is suggesting pushing out a protocol that immediately allows larger blocks. I think 420,000 is too late, we already have 500KB+ blocks from time to time. I'll bet in 6 months, every block will be 500KB+, and in 1 year all blocks will hit 1MB limit. |

The difference is that you can't double spend your credit card, so the promise to pay is as good as money in hand, unless the customer go through the chargeback process with evidence and take on legal liability (the shop can sue the customer in small claims court if the customer is committing fraud).
Dubious distinction. Fraud is fraud that is all that matters to the merchant. I mean it is like saying sky diving in the desert without a parachute is safe because you can't die from drowning. It is trivial to wrongfully charge back a purchase made with a credit card, especially one made online. Still even if so called "friendly fraud" (costs US merchants about $100M annually) was impossible a credit card authorization is no good if genuinely fraudulent. If it isn't Mr. Smith using Mr. Smiths credit card then you are going to get a genuine chargeback. The comparison is correct. unconfirmed bitcoin transaction = credit card authorization. If the customer is legit you have nothing to worry about. If they aren't you could be losing money. No, there's a huge difference. With credit card, the shop can be pretty sure that most of the people isn't going to fraudulently chargeback, the chargeback process takes a lot of time and effort to go through with. Also once you are flagged as a chargeback abuser, you can no longer successfully chargeback. But double spend, is trivial to do, it's simple as sending two transactions, one with a fee, the other without. There's no time or effort involved, also you can do double spends as much as you want, with no one stopping you. Well no none of that is true. All reference nodes will reject and double spends. However for the sake of argument lets say your right it is trivially easy to perform a double spend AND it is virtually impossible to perform a chargeback ($28B would say otherwise). What happens when the credit card is genuinely used fraudulently. Ooops. An authorization is just that. It is a request for funds. A request which can after the fact be denied for a variety of reasons. Nothing is "confirmed" until the tx clears in 180 days. There are genuine frauds in both credit card world and bitcoin world. I'd say the number of frauds is significantly less in credit card world percentage-wise. Though bitcoin world is increasingly getting better in this area. "no chargeback" isn't really better, you are just deciding which party to screw. In creditcard world, the rules screw the merchant, but the merchant is able to better absorb the cost by raising the price, AFAIK it's very rare for a merchant to go bankrupt by having legitimate chargebacks. In the bitcoin world, the rules screw the buyer (unless some form of escrow is used), and it's pretty easy for a single person to go bankrupt by being a victim of a fraud/hack, as we have seen many times here. This is why silkroad, bitmit etc all recommend/require escrow for their transactions. Again, my point is physical shop transactions with Bitcoin CAN NOT become popular in its current form, without 3rd party involvement, it's simply illogical. This is why after 4 years, physical shop adoption is nearly non-existent while online Bitcoin use has exploded. To have physical shop adoption, there must be a 3rd party service that can guarantee valid instant transaction in Bitcoin. I believe coinbase would be a good candidate for this, since it already host user wallets and handle payment processing. |

I don't understand what you mean 7 hours is not long.
Is there a way that I can confirm coins have been received within say
the amount of time it takes me to swipe my credit card is a shop.
Am I missing something?
You are missing the fact that when you swipe your credit card, the shop does not immediately receive the money from you. All they receive is a promise to pay. The shop then has to wait for the payment processor to settle the balance (perhaps at the end of the day?) before any money is transferred into their bank account. Even then they have to hope that you don't dispute the charges, forcing the payment processor to take the money back out of their account. With bitcoin, they can see the promise to pay within seconds (just like with a credit card). Instead of having to wait until the end of the day to have the promise to pay fulfilled, they can know that the money is irreversibly theirs as soon as the transaction is in a few blocks. (generally within an hour if a proper transaction fee is paid). It's likely that miners will eventually look ahead at chains of unconfirmed transaction to determine priority. This will allow a shop to pay a fee on behalf of their customers to ensure that the transactions are quickly included in a block. The difference is that you can't double spend your credit card, so the promise to pay is as good as money in hand, unless the customer go through the chargeback process with evidence and take on legal liability (the shop can sue the customer in small claims court if the customer is committing fraud). This is the reason why Bitcoin in its current form can never become popular in instant physical shop transactions, a 3rd party will have to be used, for example bitpay/coinbase(if they offered such service), to guarantee that a 0 confirmation transaction would not be a double spend. |

(because a hacked blockchain.info could feed you evil Javascript,...
Their browser addon eliminates that risk, no? yes, but not everyone uses it. |

It happened already, it shot up to nearly $22, then corrected to $18. There would be another correction coming if it shoots up to $27.50
