Bitcoin / Project Development / [ANN] mysatoshis.com - a mobile btc balance web app
|
on: May 19, 2013, 09:27:11 PM
|
I have created a small web app that I want to share with you that I am using to check the balance of my bitcoin addresses. The application stores your addresses in local storage (and is therefore only compatible with modern browsers) and checks the balance directly against blockchain.info. Your addresses are never sent to my servers! It also calculates your net worth, based on currency information from Mt.Gox. You have the option of seeing either the last, high, low or weighted average price that is returned from Mt.Gox and also which currency you want to use. Besides this you can also select the number format you want to use (for us Europeans) and the bitcoin unit you want to use. I have posted all the code on github ( https://github.com/icellan/mysatoshis ) so you can see that I'm not doing anything sinister. Feel free to fork or copy or do whatever you want with it, I just want to contribute to the bitcoin ecosystem. Some screenshots:    I hope it's useful to someone! PS: I would love to remove the mtgox.php proxy script from the app. If someone can tell me how to get the currency info directly from Mt.Gox in javascript (without cross domain issues), I would be grateful. |

At my current supply of btc (small) I'm personally waiting to sell a bunch if it ever hits $10k ea. I have a mortgage to pay off. If, however, it looks like it'll easily climb through $10k, I'll put in a buy at $10k once it surpasses it, hoping to catch it on the decline, but otherwise will see where it goes.
I was thinking exactly the same thing, but missed the boat when BTC was at euro 35. My bank money transfer didn't work :-( eventually bought at 47. A few days ago I tried again, wanting to buy some more BTC. Price was at euro 74, but bank failed me again. They blocked my account. Eventually managed to buy at euro 85. So, lost a few euro's due to bank failings, shouldn't complain, others lost a lot more. Hope to recoupe with BTC's skyrocketing. |

Bitcoin / Mining / Re: I just realized why I need to start mining, so a question for miners

“The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.”
The importance of the above quote struck me last night. So I want to throw in my .02 btc of being an honest node and add some hashing power. I'm not worried about spending a few more dollars on electricity than I make in bitcoins because Bitcoin has already treated me so well.
I mined on my laptop back in the day but stopped when it went to GPUs. Now, looking at mining has the same effect on me as the first time I encountered Bitcoin itself. It's confusing for us non-miners. So perhaps an expert or two could help clear up the confusion.
My question: What's the lowest impact, cheapest method of adding 1-2 gigahashes/s to the network? As said, this is just to be an honest node as I'm not worried about profit from mining.
Thanks!
Good for you for realizing the importance of why Bitcoin is so important. Impartiality. So, now, with the right philosophic point of view, go get yourself some ASIC's. Where can we get some? Butterfly labs seems to be DOA and Avalon is sold out. |

I think the biggest bang for your buck is the Radeon HD 5970 at the moment, if you can get it second hand.
What do you means exactly by "externally through the PCI on my laptop"?

Hi. I'm icellan. Getting bit hard by the bitcoin virus.
Background as a developer and am looking to create a business around bitcoins.
The whole idea of a currency that is out of control of the central banks and market manipulation just sounds awesome.

Hi All,
I am new to the bitcoin community. I have known about it for years, but never got involved, until now that it's getting more press, I finally dug in and I am really excited.
I have been trying to do some mining at home, but with very little results. My old GPU rig is ancient is getting very low MHash/s.
Does it make any sense, at this point in time, to get into the mining game without an ASIC?
Thanks.
Mining with GPU's now is not to cost effective, however ASICs are just showiing up and not many are being shipped yet (to my knowledge) if i had some spare money right now i would invest in fpga miners, they're cheaper than ASICs and you can get a raspberry PI to run the mining software on which is an extremely power efficient solution (at least in my opinion) and fairly cost effective. That's awesome. I happen to have a RaspPI lying around unused. What FPGA's etc. are you able to install/use on it? |

if you have multiple gpu's
i would say mining with only one or a very basic setup at this time is not worth the total effort.
But calculating the ROI on http://www.bitcoinx.com/profit/, even with a Radeon 5970 running at full speed, it will take 1 year, 73 days to recoup the money. And this is assuming difficulty and bitcoins per block remain the same, which is not realistic. Running two cards at the same time does not really change the calculation. [edit] My previous calculation for the Radeon 5970 were wrong, apologies if I scared anyone ... an ATI Radeon 5970 has a hardware break even of only 43 days at the moment. [/edit] |

I would love to do something similar, but listen to the people that have been in this longer and don't waste your time. This is all about trust and you will have to clime a giant hill to get anywhere with your new currency at this point in time.
I totally get it, as I am also late to the game. I have been breaking my brain for weeks how I can get in the game, but the best you can do is setup a legitimate business around BTCs and invest in a good rep. There is no free lunch around this, but that's why it is starting to be worth something.
