If I wanted to generate an empty fresh non-HD wallet using Bitcoin 0.15.0.1, how would I go about it? or is this not possible?

I don't like HD wallets in general, I like the old approach better. Im not sure how exactly this HD wallet works, I just like the original format. As far as I know, there is no seed, so the wallet cannot be generated unless you own the wallet.dat file which is good, I wouldn't trust a wallet that can be generated with a single seed containing all of your private keys.

What are the pros and cons of the new HD enabled wallet.dat compared to the original format? I've had the same wallet.dat since Bitcoin-qt in 2013-ish and I never had any problems with it. But now with all the fork nonsense I will be forced to move my coins into another wallet, and when I tried to generate a new wallet in the new versions of Core it was HD-enabled.

The Queen of England Elizabeth II, Soros, Sheldon Adelson, Queen of Jordania, Juan Manuel Santos (president of Colombia), Justin Trudeau (Canada), some people close to Trump, big celebrities like Bono from U2, Madonna.... huge list.

The elite continues avoiding taxes with their billions, meanwhile they will hate you for owning a small 5 figure bitcoin holdings and will put you in jail if you don't tax it.

You can click on there and read the press release. I think this will pass, it's not the SEC that regulates this, it's a different process from ETF's. I think we are still not ready for an ETF, but Bitcoin futures could be good. Some worry about price manipulation as similarly seen by gold. I argue Bitcoin is a much different asset and you can't manipulate it as much as gold. The supply is clear, the market is global and nonstop. Gold's supply is unclear, nobody knows what's the limit of gold or how much is out there. The markets are not as global and they take breaks.

Good times for Bitcoin holders ahead, once again. I think we'll see the ETF around 2020 with an active lightning network, and the march towards 6 figures a Bitcoin will begin.

As we all know, there is a lot of hashrate with an intention to mine Jeff Garzik's coin, also known as Segwit2x, B2X, S2X, or any of the different flavors.

We know that this 95%, 90%, 80%, or whatever percentage number of intention of miner is total bullshit and will be exposed once the market starts talking. But we also know that there is bribing going on, in order to incentivize miners to keep mining at a loss, probably covering their losses + an extra profit for the effort. Obviously their goal is to kick "Core" and establish themselves as the main branch developers.

The question is, how much money can they waste on bribing miners to cover their losses? If this is an operation funded by US Government, PBOC, or whatever other similar institution, they can print a lot of fiat to keep miners mining at a loss. This could be a problem. Don't forget that none of these NYA signers care about Bitcoin's sovereignty, they just want more fiat.

The abstract:

Simplicity is a typed, combinator-based, functional language without loops and recursion, designed to be used for crypto-currencies and block- chain applications. It aims to improve upon existing crypto-currency lan- guages, such as Bitcoin Script and Ethereum’s EVM, while avoiding some of the problems they face. Simplicity comes with formal denotational semantics defined in Coq, a popular, general purpose software proof as- sistant. Simplicity also includes operational semantics that are defined with an abstract machine that we call the Bit Machine. The Bit Ma- chine is used as a tool for measuring the computational space and time resources needed to evaluate Simplicity programs. Owing to its Turing incompleteness, Simplicity is amenable to static analysis that can be used to derive upper bounds on the computational resources needed, prior to execution. While Turing incomplete, Simplicity can express any finitary function, which we believe is enough to build useful “smart contracts” for blockchain applications.

This looks like an improved Bitcoin Script, which could be delivered in a softfork just like segwit.

I wonder: Do "smart contract" altcoins have any future? Between this and sidechains like Rootstock, it's going to be thought for alts when it comes to justifying their existence. Why are people going to want to deal with more tokens when BTC does everything'

I was reading old posts to try to find what people were saying back in the day about BTC reaching $5000 and found interesting post such as this:

Not going to happen.  I doubt we'll ever see $100 BTCs much less BTCs selling regularly for thousands of USD per BTC.  Not in 20 years, not in 100 years.  Just think about how much bid depth you'd have to have to absorb even 1000BTCs at $5000 without slipping, say, 10%.  At just $100/BTC you'd have to have somebody with a single $100,000 bid at 100$/BTC not get any slippage.

The price might make another go at the previous all time high, but just like the pump and dump that induced that high last time, it won't hold there but momentarily because there simply is not, and probably will never be, the necessary depth to keep the price up.  I'm confident we haven't seen the last of single digits, and we'll probably still be seeing single digits years from now.

Source: https://bitcointalk.org/index.php?topic=100487.0 (not necessarily post here, admins dont seem to like old threads being brought up again for some reason, but it's good to read this for historical reasons)

Also a lot of people were talking about the scaling drama already back then.

It's funny here we are hitting $6000 now. A lot of people posting there sold and are now depressed for life.

With all the hacking of accounts going on in the forum in the past few days, I've been learning about the signature and verification of messages through bitcoin addresses. It's pretty easy and straightforward, but I realized that in order to recover the account, you need to search through your endless amounts of receiving addresses to find an address that will fit the criteria for address recovery (an unedited post, a quoted post, or a closed thread that contains your address before the hack). If you only have one wallet in your entire history on bitcoin it should be there, but if you use different wallet files (now a growing trend due the forks) you need to search through the wallet addresses and it's annoying.

It could be so much easier if we could have a simple search bar to copy and paste the address there and automatically find it. Since one tends to create one address for each transaction, the receiving address window has an huge list. I know you can just export the file and search there and you could list all in the command console and use ctrl+f, but it would be cooler if we could do this in the GUI and save time.



Maybe make it possible to search Label column too in case you know you want to find your "Blog address" but don't know what address you used for that.

Suggesting an update that will properly ban 2x nodes, given that they are hiding their nodes now and avoiding disconnecting from them.

Example of spotted node while running 0.15.0.1:

"subver": "/Satoshi:1.14.4(2x)/",

https://github.com/btc1/bitcoin/issues/135

This is a serious attack on bitcoin so we need serious protection. The question is, why does the Core node code use only subversion to detect rather than service bit or both?

Since I like running my own full node to transact, I need to keep my wallet.dat safe. The dilemma is, how can transacting within a full node be ever secure? If we admit that every computer that's connected to the internet is compromised, it is a hard task to keep it safe.

My idea is to keep my Bitcoin Core full node client synced, but only add the wallet.dat file when I need to transact. Once im done transacting, I would close Bitcoin Core, copy my wallet.dat into my USB, and then proceed to delete wallet.dat with a software such as Eraser (https://eraser.heidi.ie/)

This way there wouldn't be nothing to steal anymore, and the only moment you are exposed is during the transaction.

I was wondering if there is a device that would allow you to safely use your wallet.dat within your full node in an isolated way? Never used a Trezor but that's not what it does I think.

It's obvious $2800 was the bottom. Technical analysis pointed an obvious trend reversal there. Also a lot of people were under the influence-mind control of Goldmans Sachs searching for the $2200 prediction that they gave. Of course, Goldmans Sachs along with Jamie Dimon and China area all FUDding on purpose to buy cheap Bitcoin, they would never give you a perfect entry price, so a $+500 margin seems reasonable, hence the $2800 bottom.

They just got a ton of cheap BTC from panic sellers and positioned themselves in this unavoidable post-bitcoin reality where the most precious asset of a country will be to hold Bitcoin. This is game theory at work, nations fight and FUD to be the dominant Bitcoin states. Get yours or get fucked.

Ark has gone to all time highs recently, breaking its current resistance of 0.00041 BTC that we say two times.

Can anyone explain why is ARK rising so much? any technological updates? any hyped out partnership with big brands? it got added to a big liquidity exchange? just a random pump (and dump..)?

I can't keep up with the never ending amount of altcoins. What are some ARK competitors?

https://news.bitcoin.com/japans-internet-giant-gmo-launching-bitcoin-mining-with-7nm-chips/

Japan’s leading internet conglomerate and bitcoin exchange operator GMO has announced that it is expanding into the businesses of bitcoin mining and chip manufacturing. The company revealed plans to produce and sell 7nm semiconductor chips and run a mining facility in Northern Europe.

"We will operate a next-generation mining center utilizing renewable energy and cutting-edge semiconductor chips in Northern Europe. We will use cutting-edge 7nm process technology for chips to be used in the mining process, and jointly work on its research and development and manufacturing with our alliance partner having semiconductor design technology."

This 7nm would outperform the current generation of Bitmain's Antminer S9s. It will take a while until Bitmain catches up, this means that we may finally see some cracks in the ridiculous Bitmain's evil monopoly (evil because they promote dogshit like Bitcoin Cash, do evil miner things like mine empty blocks then complain about fees etc)

I hope more and more big players enter the game of mining. I remember Putin wanted to get in too, and im sure USA will be kicking miner ass too. nVidia and AMD will be there soon too with their own ASICs. This mining game has only begun. Bitmain's monopoly will be over sooner or later.

Do you think this is realistic?

If BTC grows to such heights, the overall graph must look like that, since it must go up exponentially, therefore with an exponential curve. The difficulty is knowing when and how.

This prediction includes a $7000 prediction during 2017 fired up by a SEC approval of a Bitcoin ETF. The question is... how likely is it that an ETF for Bitcoin happens during 2017?

We've had already two (to my knowledge) failed ones during 2017. Who else can try to get the job done and actually get it approved?

If big blockers don't want SegWit2x, and conservative blockers don't want SegWit2x... then who the hell wants SegWit2x?

Apparently nobody likes this, but apparently, it is backed by 80%+ of the hashrate, and backed by a bunch of big online wallets, merchants, and other groups. They all claim it's what the users want, but clearly, the users that are technologically literate enough to know what's going on, aren't supporting big blocks of any kind. And these that are confused or just don't care about decentralization, are already happy with BCH's big blocks.

Then who the hell is supporting this damn think? I can't stand Jeff Garzik anymore and the rest of suited up retards like Barry Shillbert thinking they are smart.

Byteball got some interesting technology, but the distribution is clearly a problem for investors, the inflation pressure is too big, the supply gets getting expanded lowering the price. My 2 questions are:

1) When is the last distributon stage going to happen?
2) What is the final byteball supply?

Can someone that has created a Bittrex account recently explain what are the features of their account?

Some people were reporting a 3 BTC limit for withdraws, but when I created it, it was 1 BTC limit, and it required real place of birth, real full name, real address etc (they check against public records, so you can't lie, if you lie, they ask you to enter a real phone for an SMS confirmation), and this is to trade crypto to crypto too, so it's not like they allow you to trade between cryptos without confirmation.

But now im hearing 0.025 BTC limit for withdraws which is ridiculous.

I know some people got lucky and got "Legacy" accounts, but these will be over soon or that's what Bittrex has been saying for a while.

As we all know by now, Poloniex is off. They are claiming it's "connectivity issues". If I had just 1000 bucks there, I would already be nervous.
I went to their twitter, and their last update was 3 hours ago. Reading the comments, I see this:

HonestCryptoTips‏ @HonestCryptoTip
Volatility = Profit for my fund. Some people have the stones to go balls deep in places others don't. 🤷‍♂️

It's crazy how much money some people have. To think he has half a million in some cryptocurrency exchange. That guy must be so rich.

I see a lot of people confused about how to access their coins, and unfortunately, most people don't run full nodes and resort to easier (but less safe) routes like Electrum.

Here is how you get your coins without screwing it up in the process (this is directly from the official Electrum website) :

Recommendation on how to redeem Bitcoin Cash
============================================

July 31st, 2017.

Electrum is a Bitcoin wallet created by Thomas Voegtlin in 2011.
Electrum is distributed by Electrum Technologies GmbH, a company
registered in Germany, using the website https://electrum.org


Electrum users who are not interested in Bitcoin Cash do not need to
worry nor to take any particular action. The following note is only
for users who want to access their Bitcoin Cash (BCC).

"Electron Cash" is a fork of Electrum for Bitcoin Cash. Electron Cash
is not endorsed by Electrum. It is open source, and binaries
(executables files) are available for Windows, OSX and
Android. However, when you run binaries instead of source code, you
have no guarantee that they match the source code. This is why wallet
binaries are usually signed by developers. A digital signature engages
the responsability of the person who signs.

The person who distributes the Electron Cash binaries has decided to
remain anonymous, and uses the fake name "Jonald Fyookball" in order
to sign Electron Cash binaries. Thus, if these binaries contain code
that is designed to steal your bitcoins, the author of the theft will
be anonymous and walk away safely with your funds.

This danger is exacerbated by the fact that the default behaviour of
Electron Cash is to silently copy all your Electrum wallets into its
own directory. Thus, if you run Electron Cash on a machine where you
previously used Electrum, all your pre-existing wallets will be
available in Electron Cash, and you will only need to enter your
password in order to expose your bitcoins to potential theft.

Therefore, users who want to run the Electron Cash binaries should do
it on a separate same machine, that does not have their Bitcoin
wallet. We recommend to proceed as follows:

 1. Install Electron Cash on a machine that does not have your
 Electrum wallets.

 2. Wait until the BCC hard fork has taken place, and a few BCC blocks
 have been mined.

 3. Move all your Electrum funds to a new Electrum wallet. This will
 move only your BTC, and not your BCC, because the BCC blockchain has
 replay protection. Wait until the transaction is confirmed.

 4. Enter the seed of your (now empty) old wallet or private keys in
 Electron Cash. Since the BTC have been moved to a new wallet,
 entering your old seed in Electron Cash will not put your BTC funds
 at risk.

Following these 4 easy steps you will be able to access your BCC
without compromising your BTC.

I was wondering what happens if you generate a key, and then send coins to yourself on that key, all within the same wallet.

Let's say you are using Bitcoin Core, you generate a key, then you use coin control to send some coins you want to de-attach from an address into a newly generated address, is that a good privacy practice? It's like a cheaper mixer with only "1 pass" protection.

I don't want to use mixers, because im scared to get "tainted coins". All of my coins are legal and im not doing anything that worries me, other than personal privacy. I don't want to mix my coins with other coins that i have no idea where they come from.

And I just wonder how does this work. The transaction happens just like a regular transaction if you send it to yourself I guess? or is it faster somehow?

People are speculating about the up and coming Bitcoin Cash, also known as Bitcoin ABC (are they the same thing? I think they are). Let's call this BCC. This is considered a hardfork right?

Anyway so from what I've understood, when a fork happens, if you own the private keys, you will receive exactly the same amount of coins in your wallet, on the other chain.  This is why it's very important that you must own the coins by the time the fork day happens, or else you will be at the mercy of exchanges listing or not the forked token.

My question is: If im keeping my coins in Bitcoin Core, how do I access the Bitcoin Cash tokens?

I have tried to find an answer and im confused. Some claim that the wallet.dat files will be compatible with the Bitcoin Cash full node, so you open it there and it will work. I think this will not work.

If so, how does it work in detail? I want to be able to dump these damn BCC tokens to get some free BTC.
