Thanks I will probably add more options and statistics soon, but I am still thinking about what would be a good indicator. Those calculators that estimate the earnings considering an X% difficulty increase are far from accurate..

Just to be sure: are you talking about 10 000€ or 100 000€? The thread title is different from the post text. And how about prices? How much are you paying for coin?

I decided to write a small tool to look at past mining investments. Besides being a regular bitcoin calculator, it can also analyse data to answer questions like: "If I had bought 3Ghash in June, how much would I have made?" Here's the link:

Maybe we can learn something from the past that will help us predict the price/difficulty movements in the future... Anyway, suggestions/improvements and overall feedback are welcome

What about transforming this into a list of Built/Tested/Shipping ASICs/FPGAs + possible upcoming ASICs/FPGAs? I am just suggesting it because if I want to buy a board, I might want to know about the possibility of getting a much better deal two weeks from now. Essentially, it would be a more complete buy guide with proper warnings for untested/unconfirmed new material.

My rule of thumb for forum posts is: if there are more than 2 quotes with a reply underneath in a single post, then it is usually not worth reading because it is a pointless discussion where both sides could be correct (others may call it feeding the trolls ).

Are you planning to open to other european countries soon?

So what's the difference between this and StrongCoin for example?

Google Checkout's terms are not really clear. The only "official statement" was a post in their forum saying that it was allowed. However, they will close your account if you get lots of chargebacks. So, theoretically, you can use Google Checkout to sell bitcoins the way btcnow.net is using.
On the other hand, Paypal explicitly forbids selling currency, but they probably won't notice it until they receive the first chargeback...

Paypal will freeze your account. It is explicitly forbidden by their ToS to sell digital currency. "It's an MtGox code" does not work as an excuse.

I thought it was the height, but that wouldn't work. What exactly is the block index?

Sorry for my bitterness but when I first got here there were 'flashing signs' all over the newbies section saying stuff like "wallet.dat is the most important file ever", "solo mining is not worth it", "we don't accept paypal", etc. I was just wondering what did he read during those 4 hours...

Anyway, OP, here is some help: http://tpbitcalc.appspot.com. You need to wait around 2 months to mine a block with those cards. This is a probability, which means that you may hit a block next month or 3 months from now.

I wonder how could you spend 4 hours in the newbie section without realizing that you can't solo mine with that hardware and that lost wallet means lost addresses.

Currency? Country?

That's basically where we are headed: partial centralization (well, right now is mostly a monopoly because 80% of the money goes through MtGox...).
 
Anyway, you described green addresses. The rest of it will naturally happen. When laws are made, exchanges will need to get additional paperwork done which will increase trust from users. When the network volume grows, there will probably be "supernodes".
Centralization is much more simple to people, I can understand that. But the underlying protocol will still be open and somewhat decentralized.

I was checking your API and I noticed that you only have rawblock information until block 124620. This works: http://blockchain.info//rawblock/124620 and this doesn't: http://blockchain.info//rawblock/124621

Also, there seems to be a problem with the timestamp. Take for example the block 2016. The rawdata shows the timestamp 1233063531, which corresponds to 27 Jan 2009 13:13:16, but in the block page you show 2009-01-27 13:38:51.

I also added you here.

This reminds of those people who say things like: "The lottery numbers were so weird! Who would have guessed that?"

Not for the best reasons I suppose...

Thanks a lot Inaba. I'm eager to read your review.

There are some users at bitcoin-otc who will sell/buy bitcoins in Euros - me included. Head over to the irc channel or look into the orderbook.
