Automated payments = bleh.

What I'd like to see is a 3rd party payment processing service that automatically sends emails with a total amount due and remit-to address to my subscribers every X number of days before their bill is due.  If payment is not received by the due date, their account will be disabled.
6902  Bitcoin / Development & Technical Discussion / Re: Majority Protected Wallet Storage on: June 27, 2011, 11:32:54 PM
How about....

An application for P2P storage of all wallet files, such that you set yours for upload, and it is automatically downloaded by all other P2P users.  Of course, wallet files would be truecrypted.

Unless a way is found to break truecrypt encryption, then the wallets are very safe from accidental destruction, and very secure from those that would do harm with backups.

I like this idea! 

Only part that makes me nervous is "Unless a way is found to break truecrypt encryption...".  If a way is found, POOF!!  All coins are lost.  Or, maybe if the wallet is broken into many chunks and the p2p network had no knowledge of which chunks go together but the client would be able to figure that out based on passwords/key files/etc and some algorythm, and then retrieve the needed chunks from the network in order to rebuild the wallet?  Or something along these lines.  Interesting!!

Yeah, I would have no idea how to actually go about coding something to support an "everyone's wallet" P2P storage system, but I think it's a good idea.  The risk of 2048 bit encryption being cracked is relatively slim.  Even if it was cracked, the perp would only have access to one wallet, since each wallet was encrypted separately.  And you'd probably hear about it before too many more wallets were cracked, giving you plenty of time to create a new local wallet and transfer all your coins to it (and then create the obligatory "I've been hacked, please donate!" thread just for kicks).

One potential problem is that of bruteforcing the password, but with sufficient length, it would be impractical for an attacker to go after yours.  Just make sure it will outpace that computing law (that states a doubling of power every 18 months) for your lifetime, and you should be fine.

I suppose I would be nervous giving an application access to my wallet file...

I'd also need an android-based phone to use this.  Tongue

mybitcoin.com is the last place I would look for security.  They did nothing about the MtGox security breach, so users lost over 4k BTC from the site.

What could have they possibly done? They were actually quite preemptive, blocking and changing passwords of same-name accounts. You cannot blame them for (1) MtGox leaking its passwords and (2) people using the same username/password in both sites, which are so related and critical in terms of security.
Where's my squinty eyes smilie when I need it?

But that's a vastly different story from what I heard.  I heard they did nothing, then a week after the MtGox hack, a bot logged in to dozens of mybitcoin accounts and emptied them all within minutes.  If that's not true, and they forced a password change of same-name accounts, then more power to 'em.

I, for one, would welcome some good old hyperinflation.  The interest rates on my student and home loans are fixed, so a massive increase in valuation (compared to USD), would be very welcome.  The hardest part would be WHILE it was happening, and continuing to be able to buy food, gas, etc until I got a cost of livings wage increase.  But once the dust settled, anyone holding assets secured by debt would come out way ahead.

The downside is, my meager 401k would become virtually worthless.  Well, unless the mutual funds it is invested in somehow rebounded.
6906  Bitcoin / Bitcoin Discussion / Re: Market is saying Tradehill is new leader on: June 27, 2011, 09:44:48 PM
I disagree.

In all likelyhood, it just means that more people who want to sell have accounts at MtGox, and more people who want to buy have accounts at Tradehill.  Arbitrage will take care of the major discrepancies, but there will still be some differences in price that go uncorrected.

It is possible to add data directly to the block chain.  You send a coin to yourself and encode info in the script.

The new problem becomes forgetting your password, rather than losing your wallet Smiley.
In my opinion, that is a better problem to have.  Smiley

I own a pizza shop and I want to accept bitcoins but I'm still majorly concerned about how to keep my coins secure on windows.

Set up an account on mybitcoin.com and pick a very strong password.  Use the online wallet just as you would a local wallet.

Frequently change your btc to usd at one of the exchanges so you're not exposed to too much currency risk.  The minor risk of losing some bitcoin will be equivalent to having your local cash registers robbed.  The upside is the love of all the local BTC users.

(I am in no way affiliated with mybitcoin.com, but their site is pretty slick.  I like it.)

6910  Economy / Trading Discussion / Re: Acumulated ask/bid graph over mtgox depth of market on: June 27, 2011, 09:28:39 PM
My graph was shut down by my webhost since it had recieved 10 000 requests, i think it was at 19 june but im not sure. It was probably a attack from the same people who dislikes bitcoin (apparently some people do that).

Since mtgox still isnt up yet, I will wait with reopening the site.
If you want, I'll host it on my webserver.  I've got plenty of extra bandwidth, etc.
6911  Bitcoin / Bitcoin Discussion / Re: How To Get Difficulty Down? on: June 27, 2011, 08:25:09 PM

6913  Other / Beginners & Help / Re: Who the hell is hoarding his spare change? on: June 27, 2011, 07:01:35 AM
so mtgox is in possession of a third of all existing coins?
No.
All those around 47k are transactions from the same address of ~48k.  It sends X BTC to Y address from address Z, and the change to ZZ address, then sends XX BTC to YY address from the change address of ZZ.

So it's not 2M bitcoins in that wallet/address, it's only 48k.

6915  Bitcoin / Development & Technical Discussion / Re: Vanity bitcoin addresses: a new way to keep your CPU busy on: June 26, 2011, 09:31:29 AM
I use MinGW.  I know next to nothing about c++ or compiling (web programmer here), so I was hoping there would be an easy way to include a patch (or diff?) file when I run the compile command.  If I find something that works, I won't upgrade my client until I absolutely have to in the future.

looking at alot of the password makes me question the demographic of the bitcoin community.
LOL, so true... also saw "pooppoop123".

Moral of the story: length means nothing if your password is still easy to type

My password isn't on there, and it isn't long at all. But it's hard to type. That said, I expect it to be found in the next few days.

can passwords contain characters like....  ¿ ¼ ©

mine was 13 characters long, so it looks like they only got to 12 characters in length and were almost up to mine  Shocked
Mine was only 9 chars, and wasn't on that list.   Huh  Is this only the unsalted pw's?

Sell out why? .... they can just trickle them in over a long period of time ... as and when is needed.
This.

The big holders are probably the ones responsible for not letting the price get up too high.  Many of them are probably trickling themselves a nice $10k/month or so.

Really?  REALLY?  So because I might not make a profit tomorrow, I shouldn't mine today?  That's the most absurd logic I've ever heard.

I'm paying for my electricity 6x over.  There is absolutely no reason for me to not mine.  It would make zero sense.

Sgt. Spike, I was directing my comments towards newbies who might be fooled into thinking they can make an easy steady profit by mining.  At the current difficulty level, mining doesn't make sense unless you already have a GPU cluster, since the likelihood of solving a block chain is so high.  I just did a calculation using http://www.alloscomp.com/bitcoin/calculator.php

Current difficulty: 1379223.42967
Mega Hashes / second: 30.0 (that was on my dual-card Nvidia GPGPU I had used previously)
Assuming exchange rate of $15 USD/BTC, since that is about where Mt.Gox was before the big hack.

Then the average rate of return, assuming you are engaging in pooled mining is:

   Coins   Dollars
per Day   ฿0.02   $0.33
per Week   ฿0.15   $2.30
per Month   ฿0.67   $9.98

That $10 average expected revenue per month doesn't justify the energy cost of me leaving my computer on with the GPU running 24/7 at full blast.  Sorry.  Again, maybe if you are experienced and have highly optimized energy efficient equipment, then if may work out for you, but I am advising the newbies focus on using whatever unique skill set or trade that they have and offer goods & services in exchange for bitcoin instead of wasting their money buying a mining rig.  Your economics may be different though, so you may make your own decision.
You're using an old NVIDIA card - of course it's not going to be profitable for you.   Roll Eyes

When you use a single-GPU 5870 that can generate 370MH/s and uses about 200w, the story looks a bit different.  Heck, even a 6870 would be a good 10x as good as whatever crap cards you were using.

Mining is FAR from being unprofitable.  If I had more cash to buy and places to put and cool mining machines, I would do it in a heartbeat.

If mining is as profitable as all of the bitcoin fanboys would like everybody to believe, they would have cash to buy mining rigs, space, and employees. The fact of the matter is simply that it isnt. The people that think it is are exposing themselves to immense risk.
Immense risk?  Not really... the most I risk is the 25% or so I'd lose on reselling any hardware I purchased.  Hardly what I would call immense.

I bought $1100 worth of mining hardware on April 27th, when the price/difficulty ratio was roughly the same as it is today.  I've made an extra $2200 BEYOND what the mining hardware cost.  So not only do I have $1100 of free mining equipment, I also have an extra $2200 in my pocket.  And that number is still growing quite steadily every day.  Total electricity costs have been about $200 for the two months, which I am more than willing to deal with.

I'm not sure whether you're just jealous of miner's success, or whether you truly are naive enough to believe that mining isn't very profitable.  You say that "if it was as profitable as fanboys say, they would have cash to buy mining rigs, space, and exmployees".  It's not a guaranteed enough deal to buy space and employees IMO (who would need employees anyway?), but buying a decent amount of hardware is an extremely low-risk investment with an extremely high ROI.
