1121  Bitcoin / Press / Re: [2017-10-27] Warren Buffett: Bitcoin is a bubble, as it doesn’t produce value on: October 29, 2017, 05:37:20 PM
WB said years (decades) ago he won’t invest in things he doesn’t understand.  Which was why tech investments are rare for him.  And that is smart.  If you don’t understand something, it is best to stay away.

And this is another example of something he doesn’t understand and won’t invest in. He will comment on it though and show his lack of understanding. 

He didn’t like bitcoin in March of 2014 either, calling it a ‘mirage’, iirc.

The problem is that in reality nothing has intrinsic value unless there is someone who wants it. On a planet with no life, water, gold, silver, oil, oxygen, dollars, euros, and bitcoin etc have no value.  The difference between bitcoin and fiat is like that of gold, it is limited (although finding gold on the moon or asteroids would change that).  And like gold or silver, bitcoin has value because it is useful and because other people believe in its value proposition.
1122  Bitcoin / Development & Technical Discussion / Re: why 74k unconfirmed transaction ? on: October 28, 2017, 04:25:25 PM
is bitcoin network under attack ?

or its getting really popular ?

idk when was the last time i saw 74k unconfiremed transactions.

ref: https://blockchain.info/unconfirmed-transactions



I would bet a big part of this attack is due to the “Segwit2X” date being about 18 days away - around Nov 15.  The intent is likely to try to convince people it is necessary by flooding the network to delay transactions and increase fees.  This is the “hidden agenda” mentioned by ranochigo above above.
1123  Bitcoin / Development & Technical Discussion / Re: Security Risks in downloading the whole Bitcoin Blockchain from external srces?? on: October 27, 2017, 05:47:18 PM
Well, couldn't a malicious payload be embedded in the database? Something that could be lay dormant until a signal is received to activate? Think of it this way. The database resides in directories. Right now I can add files to those directories, and Core does not care. It's only operating on the files it is directed to. The additional files are undetected.
I don't get it. The user never runs anything and the blocks are merely copied to the data directory. Nothing is run in the process, not even when Core is opened, it only reads from the blocks. I've never heard of any malware that could be executed by itself, without the user's intervention.

Either that, or its in zip/rar format and theres pretty much no way for a malware to be executed either.

I think one concern here would be when Bitcoin Core is reading and parsing the block chain.  What if there is an undetected buffer overflow (stack or heap etc) or other issue in Bitcoin Core (or any other program that reads the block chain)?  This could provide an opening for attack.  It could then run an executable that was left in the block directory or code in the 'block' itself.  Buffer overflows have been a problem for decades and while Bitcoin Core is well tested, it is not perfect.  (Libraries used by Core have had buffer overflow issues in the past - e.g. the UPnP one several years ago.)

Or it could be a simple as a "ReadMe.txt.exe" file in the directory.  If only a small percentage of people on whatever OS click it without paying attention, you could have a lot of problems. 

Or (as was touched on above) suppose the archive itself is replaced with some type of malware? 

It is best to practice defensive usage so as to avoid finding out the hard way that there was an issue.

1124  Bitcoin / Development & Technical Discussion / Re: Security Risks in downloading the whole Bitcoin Blockchain from external srces?? on: October 27, 2017, 01:22:18 PM

Spendulus, if I understand you right, you mean there is a danger that one could hide some malicious soft inside the blockchain files. Well, of course every internet download should be scanned with an antivirus.

That would be a danger for the user, his computer and so on.

What I was concerned most of all was   in no case, by no means to cause any harm to the Bitcoin Blockchain network, if there suddenly appeared some full nodes with a malicious wrong database (suppose some malifactors use the hint and uploaded some corrupted databases



I think he was also saying one could hide malicious software inside the directory that stores the block chain files which wouldn't be detected by Bitcoin Core since it only looks at the blocks themselves.  Not to mention virus scanners should NOT be relied upon.  Often people are told to exclude the block directory due to false positives which would mean anything else in there would be missed even if the scan was reliable.

Another problem is that downloading this should be slower than just starting Bitcoin Core and letting it sync since it will sync from multiple nodes in parallel.  A monolithic block chain download hasn't been advisable for at least 3 major versions.

is it possible to sell our forked coin yet?

If you are talking about the 2X coin, no, since it happens in November and so there are no coins.  You might be able to sell some type of future on it.  If you are talking about Bitcoin Cash, yes.  If you are talking about Bitcoin Gold, maybe, some exchanges seem to allow it.

Thanks for the information,

I was playing around with BTC back in early June 2011 and lost interest. I found this code which I must have copied and paste from a website back then into a word doc so thought maybe it was relevant but I guess not to be.

Don’t delete it until you are sure.  As above, what is the first character?

Does anyone really care if he is “ok with the pricing”?  It is like saying, I’m okay with 2+2 equaling 4.  It is what it is due to the judgements of millions of people.

Looks like they meant $4000 premium.

As i've read, the bitcoin gold fork snapshot will happen on block 491407.

What will happen if I send my bitcoin from address A to address B at lets say block 491405. Which address will get credited with bitcoin gold?

If the transaction is confirmed in block 491405, then B.

Why wouldn't it work to download the whole blockchain, maybe you can do it in steps, 30GB this month, etc. I honestly think it's not possible for you to restore your coins withouth getting the program to sync with the network, because that's basically what it's doing when it gets the chain.

I use a lightweight laptop without the massive amount of space needed  Grin

Quote
What do you mean by a paper backup? Do you have your private key? If you do you can use some light client, which does not require you to download and sync the blockchain, and just import your keys to it.
Eg. Electrum is a good choice.

Once you have your private keys, you can transfer your coins anywhere you want to.

I have the Root Key, but I am not certain on how to use it. Do i just import it into Electrum, in which case how? Smiley

For future reference since it sounds like you figured it out, you can always use pruning which will reduce the space required, but not the time or bandwidth.
1132  Bitcoin / Bitcoin Technical Support / Re: Banning SegWit2x Node (Sybil Attack) on: October 22, 2017, 06:38:02 PM
Hey all, please keep in mind I am a complete noob when it comes to running a node.

I found some twitter posts about banning 2x nodes and 2x attacks and I'm not 100% sure what its all about.
Here a link to a github is https://github.com/mariodian/ban-segshit8x-nodes

Should we as core supporters be banning 2x nodes? Should we be doing something to protect our core nodes?

Any advise would be appreciated.


Doesn't Bitcoin Core 0.15 automatically ignores 2x nodes?

https://www.reddit.com/r/Bitcoin/comments/6sbacg/bitcoin_core_0150_will_automatically_disconnect/

It looks to me that this is effectively a ban on segwit2x nodes, since if your 0.15+ node detects a btc1 node it will automatically disconnect. All you have to do is run 0.15.0.1 and you are set.

Except that this changes the btc1/2x behavior in response:

1133  Bitcoin / Bitcoin Technical Support / Re: Help with root key issues. I fear the worst. on: October 20, 2017, 11:05:06 AM
Try moving this from Tech Support to here:
https://bitcointalk.org/index.php?board=97.0

That is the Armory subsection and there will be more users there.

However, if you have the root key and it is correct, one would think it would work.  It is the same version both places?  Did you print the hard copy or copy by hand?

if you have any idea about bitcoin increasing? if I buy now btc so its r8 or wrong time
fell free or droped here....
thanks

No one knows.  It is all guessing short term. The long term trend has been up, so if your time frame isn’t months and you know it involves risk of losing it all, then any time is okay to buy.
1135  Bitcoin / Bitcoin Discussion / Re: I am pretty confident we are the new wealthy elite, gentlemen. on: October 19, 2017, 01:38:38 PM
To think the guy who started this thread had a btc price of 10-$20 back in 2011...he sure must be an elite gentleman by now !  Roll Eyes
Yes of course the first investors in 2009 and the same years will be now quite elite gentlemen. I sometime also feel very upset, why I not bough bitcoin in the early starting years. I would also be a very elite gentleman in 2017, and the years upcoming. So nothing can be said before the time. Late come, faith come is saying in my country. There is no tension at this time. Everyone eats his luck and will be happy with that.
I agree.But there are still chances we could be the elite gentlemen in the next 7-10 years.Just keep on buying even the current price is definitely high.Then hold it for long.After all,it's the profit we are really looking forward to.And yes,it will definitely 3× or 4× from the amount we invested.And that will make us soon the new elite.

Back in 2010 and 2011 (and 2012 etc) people were saying the price was too high or “definitely high” and wouldn’t last, it was a ponzu etc. Every time I hear stuff like that I remind myself that at each new high, people will repeat the same things. But that if you have patience and wait a year or two, bitcoin’s fiat price has continued  rising.

Brazil Central Bank Chief Compares Bitcoin to Pyramid Scheme

The head of Brazil's central bank took a harsh position toward bitcoin earlier this week, comparing the cryptocurrency to a pyramid scheme.
According to RttNews, central bank president Ilan Goldfajn was dismissive of recent price appreciation in the bitcoin market. And while he said it was key to "separate" bitcoin from other applications of its underlying technology, Goldfajn said that those buying cryptocurrencies are chasing the same kind of returns as those who invest in pyramid scams.

https://www.coindesk.com/brazil-central-bank-chief-compares-bitcoin-pyramid-scheme/

That is kind of like Charles Ponzi criticizing gold and silver.  Given the mismanagement by Central Banks over more than a century, their views and wishes usually are diametrically opposed to those of just about everyone else who has any desire to preserve wealth.
1137  Bitcoin / Development & Technical Discussion / Re: Large number of unspent outputs Consolidate some outputs message on: October 18, 2017, 08:43:32 PM
how do i consolidate them exactly?

First of all, read and understand the rules of this board:
Technical discussion about Satoshi's Bitcoin client and the Bitcoin network in general.
No third-party sites/clients, bug reports that do not require much discussion (use github),
or support requests.



whats the point to spam in my topic if you just write stupid crap. if you are smart just ignore that topic and get on the nerves of your neigbours or someone else...

there are more users especially those who already posted something related

I think he was suggesting that you move this to the a different forum where there will be people who know a lot about blockchain.info (e.g. perhaps here:  https://bitcointalk.org/index.php?board=222.0. )

As far as consolidating, I believe they mean to send your entire balance to a single address, perhaps in multiple transactions so that instead of having, say, 10000 incoming transactions (inputs) you have 1 or 5.  However, Blockchain.info support would know for sure what they are asking you to do.

This topic seems to be similar to what you are asking:
https://bitcointalk.org/index.php?topic=1949251.0

1138  Bitcoin / Development & Technical Discussion / Re: Large number of unspent outputs Consolidate some outputs message on: October 18, 2017, 05:59:36 PM
which wallet should i give you as i use blockchain and its the " my wallet " function which included alot of adresses?

if you can say me how to filter and find the " bad " ones i can give you then.


does the unspent outputs get higher from time to time?  cause the sending amount is changing from hour to hour sometimes a bit higher again sometimes bit lesser ( its up to the actual btc chart ? )

1. You keep just saying "blockchain".  Everyone is assuming you mean "blockchain.info" which is a web wallet?  Is that accurate? 

2. You shouldn't give anyone your wallet.  You can share the PUBLIC keys.

3. Unspent outputs can get higher or lower if you spend or not.  I don't know exactly what this means: "its up to the actual btc chart " and I think a lot of people are confused about what you are asking for help with.

If Blockchain.info wants you to consolidate, then you should do so.

These are called vanity addresses. They are made by randomly generating addresses until one is found by chance to have a prefix that you want.


Quote
Bitcoin protocol does NOT allow addresses to be tied with names or any information. No information will be shown in the address.

However, if you are talking about this[1], the name can only be shown inside blockchain.info and nothing else. You won't be able to see ranochigo when you send Bitcoins to that address as stated before, unless you are using anything related to Blockchain.info. It is stored in the server, if they go down, the tags would all be gone. You can set it here[2].




i mean like 134mynameGDGSwU6AnkgSEqP3kZ2cKqruh

my name part of my BTC address
You can generate a custom address here (https://bitcoinvanitygen.com/). The site allows you to choose up to 6 characters for free. So you can generate an address that has your name (or at  least an abbrevation ) in it. The reason your address changes everytime is due to privacy concerns. Most online wallets give you a new receiving address each time you make a transaction. But you will still receive the bitcoin if you use an address more than once.

If you use a web site like the one above, someone else does know your private key, perhaps more than one.  It is never a good idea to share it with anyone no matter how trustworthy they claim to be.

The .09561326 Bitcoins are there with (as of now) 23 confirmations.  Unspent means it is still there and not spent, just waiting.

As far as it showing up at ICE3X, if that is an exchange, then it may be they are slow crediting it, and you’d have talk to their support.
