The more I read this thread the more absurd it gets

Work computer?
25k on computer used for browsing web?
UNENCRYPTED wallet on multiple websites?
Forensics can't do shit?

You must be either a troll or incredibly stupid. If it's the latter, and you obviously have no clue about online security, I suggest you still turn that computer off and hire someone reputable to take a look at it.

No it's my home computer. I use it to run online forums and other important stuff, plus it's trading forex right now and I had a trade going which I'm not sure if it closed successfully

the wallets were encrypted on all websites...I only had it once unecrypted on dropbox but then I deleted it when I read that their employees could read the files possibly.

the only unencrypted wallet was on my home computer...


Would you know if someone broke into your house? Who comes into your house regularly? Who has ever been in your house that knows about Bitcoin? Who knows you use Bitcoin at all?
3982  Bitcoin / Bitcoin Discussion / Re: I just got hacked - any help is welcome! on: June 13, 2011, 11:26:16 PM
so my only question is how can we be sure that this guy really had and lost all of this BTC? I mean really all a person would have to do is see someones posted address in there signature in the forums or in a reported block then post ehre saying please help me get it back! ( which translates to please help me steal this persons money for me!) lol.

But if this is in fact legitimate then i do feel empathy for you... to lose that much is horrible.. But to get that much is questionable...



I don't think many are posting addresses that they use to move their savings around with. Besides OP can prove ownership of the original address easily if there was suspicion.

I highly highly doubt this is fake and feel very bad for OP.

I think I already asked this, sorry if I missed the answer.

Could you easily implement straight BTC/USD trades on site without going through MtGox? You would still use them for moving the USD, but there doesn't seem to be a need for me to always do a market order over there with a fee when another bitoptions customer will probably come along soon wanting the other side.

It would be nice from a convenience angle too. I didn't want to sell when the price was $13 so I had to wait until it was high AND I was available. If I could have just placed an ask at $20 it would have been filled the next time I came to trade.

Hans, as you say!

However, we'll get there; there will be a tipping point in terms of usefulness, and until then, it will take a little more work to make the money.

Re: Money, yes, if you have no BTC, it takes some time to get some, and then send over. I'm guessing you guys are super-bears, so you only wish to be in BTC for a few moments max.

If you are interested in my use case: I believe btc will gradually rise over the next 5-10 years to 200k$ per btc. I would like to purchase options which will explode like an atomic bomb if my expectations are met - and fizzle in all other cases to 0. Once I figure out how to do that I will purchase. I would also agree to buy a contract for a shorter term but because btc is very volatile this is risky - and it would have to be far better than just buying btc directly.


This is more or less my situation (but with a different price target). If I saw options to sell bitcoins at $50 to $100 each three years from now, I would be very tempted to put some money down.

I should add that before I would put significant money into a system like this for a significant time, I would want some assurance that the person running it isn't going to just disappear with the bitcoins someday. For instance, posting bond with a trusted forum member would be a good start. I did that for my own little futures experiment (see sig).

To get really big, you are going to have to develop big trust somehow. I have no idea what that would take, but I know you haven't earned it yet.

While I wouldn't trust you [bitoption] with a huge amount yet, you are earning trust with me. I really appreciate all the communication and constant improvements. I can tell you are in it for the long haul.

I want to clarify something about the counterparty risk. We obviously have to trust you, but is MtGox ever holding our bitcoins? Or just our dollars? It isn't that I don't trust them, I just want to know how much I've got with them total.
3985  Bitcoin / Bitcoin Discussion / Re: I just got hacked - any help is welcome! on: June 13, 2011, 11:03:27 PM
I agree with people saying this was probably a physical attack. Wait to see which co-worker stops coming in?

I'm not sure though because of the backups you exposed and the coins left behind makes it seem like an out of date wallet could have been used. Can you examine the coins remaining and see if they are the newest addresses somehow? Was it a truly trivial amount left behind or something a thief would normal take?

Since what we need are more pointless threads, who's going to make the "I have $30M can I trade for 30M BTC?" thread.

Shouldn't you list more results if there any?

Specifying only the first 4 'bits' for addresses in my book mostly gives me a wrong result. This can be misleading and dangerous if users are not aware how it works.

It is not always 4 'bits', it depends on what other similar addresses have entered into the blockchain prior to that one. to find out how many your particular address needs, just type it in the box and it will tell you. As for it being dangerous to the naive user, thats the case with most things in life and is simply unavoidable.

Freemoney, let me know if my explanation is wrong. And thanks alot for making this, I've thought for a while something like this would be very useful!

That's right. I'd hate for people to use it wrongly, but I think warnings and extra explanation are just going to confuse anyone who can't do it correctly. I would like to hear other opinions though. In general if you aren't sure about what you are doing just don't press send on your client.
3989  Bitcoin / Bitcoin Discussion / Re: Implications of Satoshi holding 10% of bitcoins on: June 13, 2011, 07:09:08 PM
I think Satoshi whoever he/they are, chose to keep significant amount of BTC to protect the economy against an attack.
Such attack would consist of first buying huge amounts of BTCs making value skyrocket and then dumping it making value plummet. Someone with a lot of BTCs could smooth things out preventing panic

How? By selling more coins?

Now if he's rich in other assets from selling some then he can reabsorb the evil mass unleashing of coins I guess.

He could use his coins to protect us from thugs and such. Maybe build Galt's Gulch.

I imagine him waiting until Bitcoin saturates the planet, buying a sandwich, securely deleting his wallet, and moving on to his next adventure.
That will be a story cooler than any Hollywood movie.

Indeed.

Here's more:

The sandwich shop boy happens to be a block chain geek and notices that he's selling a sandwich (spoiler: to a woman) for the first coins ever minted, but he doesn't say anything. He is inspired and leaves the sandwich shop to do amazing thing X.
3991  Bitcoin / Bitcoin Discussion / Re: I'm ALL in! on: June 13, 2011, 06:34:58 PM
I was a buyer for pennies before, it seems a hell of a lot better deal after you've actually seen prices this high.
3992  Bitcoin / Development & Technical Discussion / Re: Why bitcoin cannot grow past 4 million users on: June 13, 2011, 06:30:03 PM
Decentralization and freedom do not mean that everyone has a sandwich shop. It means that anyone willing and able can have one and for the lost cost they can get it for with no artificial permissions or licenses. In the monetary realm it doesn't mean that everyone runs a node, but only that anyone who wants to pay the real relevant costs can do it and needs no permission.

That said I think it will be possible for small timers to mine (already don't need the chain) and even do it independently with a chain lookup service.

Small tx don't need to go in the chain individually either. Bitcoin will eventually make the perfect unit of account and settling in the chain can be done less frequently. The incentives exist to make people find ways to make this work well. If being a node is hard tx will be expensive and there will be more profit in finding out of the chain solutions.

And tech improves quickly.

I think you an gain adoption by catering to the newbie (like me). I do not understand options well and the site would have to guide me really well. Maybe make a dedicated page where the user can input date, strike and price of option and a JavaScript chart immediately updates to tell what this means for different price outcomes.

Feature request two: Give me an input table with 3 columns [Date, Min Price, Max Price]. The user can then enter up to 10 different dates and tell what he thinks in which range the price is going to be with 90% certainty. This wizard should generate a bunch of contracts that make the user money if he is right and lose his money if he is wrong.
This input format would remove the need to know anything about options. The user tells his opinion about the market 1, 2, 3, ... month in the future and you figure out all the math.

Feature #3: Allow orders to be cancelled after X hours automatically. That way we can risk leaving it in for 3 hours without looking.



I imagine sites spring up using bitoption to hedge themselves with names like "Bitcoin Guarantee" and "Easy Option" that have very friendly interfaces and a restricted set of options and do good hand holding.
3995  Bitcoin / Bitcoin Discussion / Re: A better (?) way to visualize Mt. Gox trades on: June 13, 2011, 05:55:07 PM
lol, donations work the other way round. you have a service and then you receive tips.
not someone pays you >$200 and then you deliver something.

Offers like this are legit imo. Of course if you are going to hold 7BTC if it doesn't make it people will be irritated. Better to escrow with someone else and only get paid if it makes it in some certain time.
3996  Bitcoin / Project Development / Re: Bitoption.org -- ESCROWED LIVE Bitcoin Options Trading on: June 13, 2011, 05:32:27 PM
I think TTBit was suggesting that adding liquidity, e.g. making a new offer, perhaps making the best current offer (bid/ask) is rewarded with a 0 commission status. Buying such an offer is charged commission, but I'd like to make sure I understood how he thinks of it.



That makes sense for driving surface spreads together, but every offer adds depth.
3997  Bitcoin / Bitcoin Discussion / Re: FirstBits.com - remember and share Bitcoin addresses on: June 13, 2011, 05:28:48 PM
One caveat: you guys should not generate the FirstBits alias if the address is not found in the chain, and explain to the user why you can't give him his FirstBits alias.

If you generate a FirstBits alias for an address that hasn't been stored in the chain yet, there is a possibility of collision with someone doing the same thing.


Of course. An address must be in chain in order to have a firstbits, maybe I shouldn't have made that smaller font in the OP.
3998  Bitcoin / Bitcoin Discussion / Re: FirstBits.com - remember and share Bitcoin addresses on: June 13, 2011, 04:46:22 PM
I'm wondering a bit about the case-sensitivity... I pasted in your donation address and got 1kk5k (all lowercase).

How does one easily expand those first bits to a full address? I thought blockexplorer searches for example were case-sensitive.

Nevermind. I see that you can just search for it on your site.


That's right. Case does not matter. I should have mentioned that in my first post. We decided that it is too hard to remember and say uppercase and lowercase.

Forgot to say SgtSpike is the programmer and does excellent work.

Good question.

You cannot guess your firstbits address. You need to enter it and find out (or search the chain yourself).

A firstbits address is the starting string that is sufficient to distinguish an address from all addresses before it in the chain. This way a firstbits can never change. Listing all matches would not tell you which was yours anyway.

Perhaps a warning is appropriate.

The main use I have in mind is a person learning one of their firstbits like they learn their phone number and using it for casual payments. It is not as great for people or situations where you need a new address each time.
4000  Bitcoin / Bitcoin Discussion / FirstBits.com - remember and share Bitcoin addresses on: June 13, 2011, 08:29:36 AM
FirstBits.com tells you how much of a Bitcoin address* you need to remember to uniquely identify it, usually only 4-7 characters. Share this 'firstbits' address and friends can find your whole address easily.

This is perfect for when the person paying you does not have immediate access to a computer and you trust them to pay you later.

Meeting someone to make a cash<-->BTC exchange? Just remember your firstbits. Say it and your partner can have your address in their client in seconds.

Here is another potential use. A shop displays an address for you to pay, you need only type the firstbits address into your phone, no need for typing 33 characters or taking a picture of a QR code.

I'm sure people will come up with uses I haven't thought of. I expect that the ability to pass addresses like this will open up some new possibilities.

*Your address must already be in the chain in order to have a firstbits address. You can send a token amount to yourself at any address to get it in the chain.

edit: Firstbits addresses are case-insensitive. This makes them a lot easier to remember and say and doesn't make them much longer on average.
