subscribers, if we break $5, you should be thinking 'purple'/'green'

If there was ever a time in the last few days to be staring at the price constantly, it is now.

omg someone tell me does purple point up or down  Cheesy

First one, then the other Wink.

can anyone in short give me an example, why buying hashing power could make sense?
if you pay with BTC, I assume, you just have a deficit.
same with other currencies in theory.

I just don't get the point.

Testing your mining pool's capacity limits for one.  Additionally, some pools pay out in ways that can earn you more if you luck out with timing.

Plus, dollar purchases are coming... BTC purchases were just easier to get started with.

Same question. Different response (not that long). http://logs.omegle.com/2548ab

Wow... people like Stranger 1 make me ashamed to be from the US.

He said American money, so I'm assuming he was talking about the Peruvian nuevo sol. After all Peru is in South America.

"The USA stands alone/we rule the world/u jelly" makes me think he is from the US... also, I don't see the word "America" in that conversation.

But thanks for correcting me Wink.

Also, it's not the stance that the Dollar is safer than the Euro that bothers me, it's shit like "stupid muslim faggot" and "we rule the world" that gets to me.

There's no excuse for (intentionally!) deleting data without backups, trying to put the blame on others just makes you look worse.

Right.

You did not think "maybe I should back this up" BEFORE you deleted it.  <---- GAP

I am in a position to make this determination because if the gap wan't there, you'd have the data you need to give me my fucking money (not that I trusted you with much in the first place).
6285  Economy / Speculation / Re: Bitscalper back to business on: March 11, 2012, 06:44:46 PM
I'd like to point out that i deleted the table trying to fix the mess that Theymos caused by going public with our username list. That's not a really professional way to help a bitcoin related business overcoming troubles and obviously not healthy for bitcoin as a whole.

Theymos's actions are no excuse for losing data.  You should have backups, or at least have made a dump before you even though about typing the word delete in an SQL prompt.

This gap in your thought process reveals you probably have a lot more mistakes to make before you've learned all the lessons you need to have learned to operate a website with the security and reliability bitcoin demands.

took me a while, but found it, what I meant is called a "type 2 deterministic wallet". see this post: https://bitcointalk.org/index.php?topic=19137.0 ("Deterministic Wallets")

Quote
Type-2 is a bit less obvious and understanding it requires you to know about a property of ECC keys, roughly:

A_public_key = A_private_key*point

Which means you can do:

B_public_key = A_public_key+B_secret*point
and have a new key which has a private key:
B_private_key = A_private_key+B_secret

So a type2 wallet stores:
Master_private_key
A large Random_seed S.

and keys are given by

Privatekey(type,n) = Master_private_key + H(n|S|type)

which works just like a type-1, the advantage of the type-2 is that you can separately secure the Master_private_key, but still generate new addresses with
Publickey(type,n) = Master_public_key + H(n|S|type)*point



Thanks... that would work.  In case it's not obvious to someone else, this may help:



A_public_key = A_private_key*point, so B_public_key = B_private_key*point

B_private_key = A_private_key + B_secret -> B_public_key = (A_private_key + B_secret)*point

Since A_private_key*point is our A_public_key, this gives us B_public_key = A_public_key + B_secret*point

Like you quoted, as long as you have the first public key you can generate all the public keys in the sequence without providing enough information to reveal the private keys.



Thanks again for digging up that information.

Most dollars in circulation are just digits in a  computer.

True, but there are no Bitcoins in circulation. Only signed transactions in the ledger (blockchain).  You cannot show me digits in a computer and say "See, this is one bitcoin."




The same could be said for dollars in a DB.

Public addresses are derived from the private key, so deterministic wallet is not the solution.  However, you are correct that you don't need the private keys.  You can simple keep a buffer of a few thousand address in your db that match private keys you store in a safe location.

I think electrum has implemented a solution where the addresses can also be derived from a seed.

I don't see how.... the private key is the only input to the formula for generate the public key/address.  Sure, you can throw away the private key after you calculate the address, but if you're hacked they will just take the seed and generate the private keys.

Do you have a link to the solution you mentioned?

I myself didn't even know of linode before. If they act correctly now, I might even consider them next time I look for a VPS provider -> successful marketing.

If you should learn anything from this incident is that you shouldn't keep any big amounts of coins on a vps, linode or not.

If all you need is to accept Bitcoin in an e-commerce, then you do not need to leave your private keys on the server. For example, you can use a deterministic wallet to generate your addresses without the private keys.

If your server needs to send bitcoins to customers (which was the case for bitcoinica and slush's pool), it is probably not reasonable to use a VPS, especially if large amounts are involved.

Public addresses are derived from the private key, so deterministic wallet is not the solution.  However, you are correct that you don't need the private keys.  You can simple keep a buffer of a few thousand address in your db that match private keys you store in a safe location.

I agree with you.
The bitcoin market is small, but way to big for my analysis to move the market in any significant way. The forecast only works if the analysis is spot on. I have observed  that if my forecast is wrong, the market tells me quickly.
Fortunately my analysis is more right that wrong.


It's probably been a reaction to all the haters, but you sure have grown much more cocky in the year+ I've been observing you S3052.  You should consider slowing your roll a little before you make a big slip.
6293  Bitcoin / Bitcoin Discussion / Re: Making a BTC pitch to a billionaire on: March 11, 2012, 05:53:24 PM
Suggest that he set up a benevolent mining monopoly which controls the majority of hashing power, but excludes all other miners. Point out the profitability of this venture as the ability to earn 100% of newly generated bitcoin with just 51% of available hashing power.

I doubt this billionaire would want to become a millionaire for the sake of bitcoin.  51% would require the largest datacenter in the world.

10 terahash is 10 million USD or about 1% of the billionare's net worth. He won't actually need 10 Terahash because many miners will exit once one agent fires up so many rigs. Once he has 51% and is able to prohibit competition, all other miners will exit mining because private mining will no longer generate bitcoin. As a result, he will be able to mine all of the world's bitcion using just a few hundred gigahash. The other 9.5 terahash can be kept offline as a threat to any potential competition. Using just a few hundred gigahash  worth of electricity expenditure per month, he will take in a revenue of 216,000 bitcoin per month or about 1 million USD per month. In about one year he will have recovered his initial investment. Certainly, if he is aware of safer investments which also have a 100% per annum expected return then he should pursue them. However it is extremely difficult to find opportunities this good.



That's hardware only.... you need a building, huge power lines, a massive cooling system, and 24 hour security to keep people from running off with your expensive hardware.  Not to mention, keeping that many rigs running would be a full time job for at least one person.

You obviously have never dealt with large-scale computing.

Yeah I wasn't talking about profiting from that.  
Definately agree.

1. Open position
2. Issue short term update to subscribers
3. ? ? ? ?
4. PROFIT!

This is somewhat of insider trading. This is criminal in particular countries.

If you don't like it, don't give him money.

Or, if you have a subscription you can't get out of, profit from it by waiting for the other subscribers to overreact.  Once they do, you will have an opportunity to profit by helping bring the market back to a sane valuation for the situation.

-MarkM-


fantastic, many thanks! I've been waiting forever for a friend to have the time to set up free hosting with email for the domain I got for my best friend - now I can just do it myself & learn how to in the process, once mastered I may move my waveaddict fan site to there but prob not without his permission & certainly not the sending payments part without that or at least it would be inactive for that until or if he decided to take it over

hope to add the feedback/testimonials from this thread to my site soon & it would be cool if the list of updates & charts sent out was mirrored to password protected pages that actually display them so one could open individually or the whole series for review etc

also I'll put up the subscriber's forum names who are public here as they obviously don't mind, though I haven't even had a chance to read the last newsletter as yet

If you need any help, PM me.
