I mean, if I want to store the whole block chain to do data analysis on a web site, what is the best database to use for that?
People generally wind up creating custom databases, or at least highly custom setups of standard database software. You are talking about indices containing many millions of records. It isn't as easy as just telling your SQL db to index a column. People often turn to tools like redis for such huge datasets. Thanks Jeff. Why would you recommend redis over mongo? |

I'm building a bitcoin website, and have been using bitcoind for database requests which has been fairly slow. We'll only really be looking at history, and not managing any wallet based functions. I'm considering switching to either SQL or Mongo for longer-term use, does anyone have experience using either for bitcoin sites? What database structure do some of the larger sites like blockchain.info use?
Thanks for your help.

The S&P is still overvalued by historical standards. http://www.multpl.com/I know you're specifically talking about financials but for a bit broader spectrum, there's the chart. Had you been long financials yesterday and today you would have gave most of that gain back. Had you been short a few weeks ago you could've easily surpassed those gains. Hindsight is nice like that. I'll give you that the banks are better capitalized now than in 2008. I'm assuming we're talking about US banks. But the US is still on the cusp of a recession and soverign default is a very real concern for MULTIPLE European countries. That's enough to bring everything down, financials (as well as small cap, biotech, etc.) will be hit the hardest. I said it before on this board, the only bank I'm really looking at right now is WFC. And I think it will go cheaper so I'll wait. Then again I could be wrong, afterall, only one person on this board is apparently qualified to understand the stock market. I agree with sentiment regarding the financial's uncertainty, however your statements regarding the P/E ratio of the S&P looks inaccurate. The Wall St. Journal reports the S&P P/E at 13.57 (a good amount lower than the 16.5 historical average). See: http://online.wsj.com/mdc/public/page/2_3021-peyield.htmlOf course, all that really matters is if the current "E" will go down from here or not, so P/E is a pretty poor indicator of value during recessions. |

This is under the ax in the new budget cuts passed last month. Do you have a link? In reality though, a lot of these airports could not survive without some sort of subsidy.
Exactly, its pure pork. My original source was a discussion on NPR last week (a little hard to link), but a quick Google search found this: http://www.vicad.com/news/2011/aug/08/bc_airport_cuts_080711_148004/?business... not a great source but has a little info. |

I spend enough to pay for electricity, which is about $65 a month for my 900 MH/s.
What % of your BTC income would you guess that is? |

Could you please make it possible for us non-miners to view the result of the poll?
Sorry forgot about that... fixed. |

The concept came up in another post, and I though I'd throw the question to the BTC Mining community to see how much people sell.

This is the stupidest thread I read all day. Congrats.
How many coins are being mined every day is totally irrelevant, it's about how many are being bought and sold on the exchanges.
Agreed, i'm out. |

That "someone else" also has to invest the resources, time, money and effort in the mining process. You can't get something for nothing. If you stop mining it is because you don't value the expected return on investment. Again, when you mine and hold you are buying the bitcoin because you value it more than the prevailing exchange rate. If you didn't think the current or projected exchange rate would be profitable then you would simply stop mining.
There's a fundamental difference between holding something, buying and selling that I feel is being lost here. |

Its not the same, because one affects the market price and one doesn't.
If I hypothetically mined 1,000,000 BTC today, the market cap would increase by ~$11,000,000 but that does not mean $11,000,000 was absorbed. If I tried to sell it on MtGox I would destroy the market.
See my clarification at post #9 above. You can't "hypothetically mine" bitcoin. It takes real resources that cost time, money and effort. When you invest these resources you are buying the product when you choose not to sell it. I was using that as an example because its harder to see the effect of not selling when its 1 btc vs a much larger number. If you had not "invested the resources" it would still have come into existence, simply for someone else. That is different than actively buying and selling on the open market. |

When you don't sell them you are signaling to the market that you value them more than the $11 - hence you are buying them.
No, buying is buying ... not selling is not selling. If someone gives me an apple that they grew, I didn't buy it. But if that same apple would be sold at the market for 2 dollars, and you could only get apples at the market, that person can either give you the apple or two dollars. Same same. Its not the same, because one affects the market price and one doesn't. If I hypothetically mined 1,000,000 BTC today, the market cap would increase by ~$11,000,000 but that does not mean $11,000,000 was absorbed.
