Hey Cryptsy users,
Does someone know how I can see who has send me coins on Cryptsy? I received coins from a stranger, but was too late to recognize his name that was showed on a pop-up.
First, find out your wallet address on which you received coins. Then use www.blockchain.info to find out more info. Maybe he attached some comment into the transaction. |

the only other one I used was bitcoin-24 who also fucked it up and still have my money/BTC. that cost me 9.4 BTC.
AFAIK, they have returned all BTC to customers, or not? |

In the times when I mined BTC on several rigs I used BAMT LiveCD distro, because there was a nice feature to monitor and manage all rigs from one place.. you could easily set primary / fall back mining pools at each rig, everything was automatic. https://bitcointalk.org/index.php?topic=65915.0there is also a BAMT version for litecoin mining |

actually it can happen that two different miners solve the block (and claim the reward) at the same time, but the network will choose who from these two miners should be the winner

depends on what do you mean with "worthwhile"... If what you are looking for is profiting from mining, then it's most likely not worthwhile to mine sha256 coins (Bitcoin, Namecoin, etc..), but it may be still profiting to mine Litecoins (LTC).. again this can change after scrypt ASICs come out. If you want to mine regardless the price/profit just to hold some.. it's still possible to mine very tiny amounts of any coins using pools. There are different calculators available online where you can estimate the revenue knowing the hash rate of your rig for bitcoins http://www.bitcoinx.com/profit/for litecoins: http://ltc.kattare.com/calc.php |

I had an idea to buy my parents a few bitcoins rigjt after 266 bubble. In the same time I wanted to try out a new exchange aside of mt.gox. So I sent about 400 eur to btc-24 exchange. Well, you know what happened next.  I am happy I haven't convinced them and lost my own money instead of theirs...  Posted From bitcointalk.org Android App |

on another note I need someone trustworthy to recover an old wallet of mine with a wallet.dat file, i cannot figure it out for the life of me.
do you still have the wallet.dat file or are you trying to recover it? |

Quite easy... mined it in half a day with ATI 5970 :p

Hi, and welcome to the forum. As you may notice I don't have a lot of posts so far, but I am on this forum long enough to give a good advice 1. To buy bitcoins you can use one of the major exchanges, currently there are 3: mtgox.com, bitstamp.net and btc-e.com. There are even more smaller exchanges (see full list for example here: http://bitcoincharts.com/markets/), but they may not fit your requirements. Basically the bigger the exchange, the more liquid market, hence more chance to do a good deal. The price is very volatile: sometimes it can move 20%-30% a day. Remember, that buying bitcoins through exchanges can be a long process: many of them (if not all) require official documents like scanned govt ID and proof of residence as money laundering protection. Another option is to use a face 2 face trade on localbitcoins.com 2. There are different strategies, you may want to check Speculation or Economics section of the forum. It is said, "buy and hold" for a longer period of time works amazingly. Also it may help if you don't buy all at once. Don't forget: don't invest more than you can afford to lose. 3. Read through forum - bitcoin requires a lot of research before making investment decisions |

I am buying BTC and hold them and even forget about them and in 4 or 5 years will look back and see what happened to them.
What do you think about this strategy?
How much do you think each BTC will cost in 5 years?
I will try to buy at least 20 or 40 BTC
Will I be rich in 5 years?
It is impossible to forget about bitcoins once you invested in them. Probably in 3-4 years you will start using them with services that will appear in your city never wanting to cash out to fiat again. Bitcoin is not only an investment but also an open market community. |

What you are describing is already happening, though we cannot see it transparently. Every early adopter has a fair price which makes him release certain amount of his holdings. There are early adopters who even sold everything, and those are called weak hands.
However I don't see the reason why should they sell their wealth at prices lower than the current demand sets. There is always a clear price between demand and supply.

Still with 7 transactions per second being the hard cap limit, I will always have a big bear in me telling me this will never grow out to compete with credit card companies. And also this issue can't be fixed.
better than having to wait three days for a stock trade to clear ...hmmm  The utopian feature of bitcoin, on which the whole "unlimited growth" picture is based (deflationary currency), simply can't be realized. With 7 transactions per second, Bitcoin can NEVER be used as a full-grown global currency for day-to-day transactions. Once the general public fully understands the implications of a 7 tps limit, this will ignite the first cracks in the giant bubble we've been in since 2011. Doesn't mean I can't make profits on this tremendous volatility though. Daytraders heaven, we are in now. the limit 7tps is set to spare resources on client nodes (CPU/Bandwidth/Memory) since the average amount of tx today is somewhere around 1. The methods exist (see link above) to address all scalability issues in case it is needed. Theoretically Bitcoin can process even more tx per second than VISA with all optimizations implemented. |

Found very good explanation of this. This is about the way of getting more miners to your "selfish" pool. My ELI5 explanation that I posed to bitcoin-development might help people understand the attack:
Alice is a miner with some amount of hashing power. She has the ability to detect new blocks on the network extremely effectively because she has controls a lot of nodes with low-latency, high-bandwidth connections; in short she has unusually good knowledge of the state of the network. She is also very good at publishing her blocks and getting them to the majority of hashing power in very little time; she has unusually good connectivity to all miners. (again low-latency and high bandwidth)
She's so good at this that when she finds a new block, she keeps it a secret! She can get away with this because she knows that the moment any other miner, like Bob, finds a block, she can immediately broadcast it to the rest of the network before the other block propagates. Instead of building on Bob's blocks, almost everyone builds on Alice's block, having seen it first, depriving Bob of the revenue. Gradually Alice gets more and more miners because all the other pools don't pay out as much as Alice's pool does. This eventually leads to Alice having a majority of hashing power, or if not that due to social pressure, a majority of the mining revenue.

Its also potentially a huge business opportunity for them.
This. Too bad they don't understand they can optimize their back-end to use bitcoin to transfer value between subsidiaries (WU nodes). When they realize the benefits there will be another company offering the same service with lower commission. |

It's no news that the $30 spike was a bubble. And this is a required paper written by a few econ students. Am I missing something here?
As not being an economist, I didn't understand most of the analysis. All I have is hope, they are correct with their calculations. Also, I don't see the reason people are arguing if the last year phenomena was bubble or not. Would it change the perception of the quality of market or something? Besides the proof that it was a bubble (even if it has no weight for me) the paper has some interesting points. But as you said, probably that's not a big quality research |

You mean "theses", which is the plural of "thesis" :-) Awesome collection, I've already started plowing through these. corrected |

Definitely useful sources, but for some reason, Google did not return this site in the beginning. On the other hand, I believe there are a lot more works in the world. Just at my school I know 1 guy who wrote a bachelor's thesis (in a small country:) ) and more are planning to do so. So, I assume, available resources dynamically increase day by day. |

Hi all, I'm new to posting, but have been watching threads for about a year. I am planning on writing a diploma thesis at school on Bitcoin topic (from SW engineering perspective), but it's really difficult to find any "official" materials. By official I mean academic papers, other people theses, etc... So my idea is to create a thread where we could consolidate all such science related works and I hope many of you will find this helpful not only in case you want to write something by your own, but also as a reader. If you wish to extend the list, please always note the source, author and year (if known). Here I start with what I have found (the order is random except for Satoshi's paper, which is considered as basic starting point) Date added

When I click a random category the design breaks up. I'm using Firefox (probably latest one).
But the idea is quite good.

Hi all, I've just tried yesterday to build my second rig on BAMT distro with 2 GPUs (5870+5850). Everything went fine, booted successfully, edited bamt.conf, pools file, but when started mining, gpumon shows only one card running (green color) and the other one is red. Picture attached. Using phatk.  I have tried to: - use another PCIexpress slot - use another card (5770 instead of 5850) - installed all BAMT fixes - in aticonfig --list-adapters both GPUs are shown - when I select second GPU in gpumon I see this (as you can see, the card is not mining at all)  I really sorry, if it was solved somewhere esle already, but I couldn't find a solution. Thanks for any recommendation. Cheers. |
