1221  Bitcoin / Press / Re: [2017-09-03] Bitcoin Mempool is Empty and High Transaction Fees are no Longer Re on: September 03, 2017, 10:25:09 PM
It's funny how people are being excited about the dropping fees. It hasn't been the first time we experienced a situation like this, and it definitely won't be the last. For whatever reason, the entity behind the latest spam attack in current situation can't justify spending tons of money on choking the Bitcoin network with rubbish transactions - result is that the mempools are shrinking in size. It's just a matter of time before we see the next major spam attack gets initiated, and once again see the fees go up significantly again it's a recurring cycle.

Probably as we get closer to November we'll see more spam attacks. Hopefully a higher percentage of transactions have switched to segwit making spam attacks more expensive.
1222  Bitcoin / Press / Re: [2017-08-31] Bitcoin Is The New 'Gold' on: September 03, 2017, 10:23:04 PM
It's really very similar to gold, there were no banks everywhere, people kept their gold under their house in their yard (wallets and keys), there were people working in gold mines(miners). Really look very much like each other.

Yep. And we are experiencing what should be "gold rush" where everyone wants to mine and take a pice of the pie. I know guys that don't even understand what BTC is but they are investing in mining heavily because they heard it's profitable

And like the '49ers, today the ones making most of the money were the ones selling supplies (mining equip, food/power etc).

Compare Bitcoin to litecoin and that will give you a big jump on it since they are nearly clones except primarily POW, block time and so number of coins generated.
1224  Bitcoin / Bitcoin Technical Support / Re: Bitcoin core or coin base wallet on: September 03, 2017, 05:02:09 PM
Bitcoin Core is a wallet.
  • you are in control of your Bitcoins.
  • you choose the fee you pay to send transactions.
  • your coins are secured by you.
  • you have to download the whole blockchain to use. (In this case, you may prefer to use a "light" client like Electrum)

Coinbase is an exchange.
  • you are NOT in control of your Bitcoins.
  • you can't choose the fee you pay to send transactions.
  • the exchange may freeze your account, steal your funds or lose your funds to a hacker.
  • it's not supposed to be used as a wallet

Never store your coins in a exchange or third party
. Only use Coinbase if you want to buy or sell coins, and afterwards, transfer your remaining funds to an wallet you control, like Bitcoin Core or Electrum.

To clarify, the blockchain is currently 120+GB so its probably best to use an exchange IMO.
Coinbase is alright as a wallet but there have been reports of stolen accounts/funds that never seem to be recovered.


electron is a good start for a lightweight wallet, if you need any help setting it up PM me, but it's fairly simple. Be sure to note down the seed it gives you.

ElectrUM is the wallet for Bitcoin.  ElectrON is the version for Bitcoin Cash (aka jihan-coin/ver-coin).  The link above is to ElectRUM even though the anchor text says ElectRON.  Just be careful to use the correct one.

The risk for an exchange with a wallet attached is that it is a big target and there have been many hacks.  Not of coinbase itself that anyone is aware of yet.

The risk for a wallet on your computer is malware.  So if you are handling any large sums of bitcoin, be sure to follow good practices.

1225  Bitcoin / Wallet software / Re: problem importing key from old multibit wallet on: September 03, 2017, 04:39:26 PM
OP seems to be very confused...

MultiBit Classic (v0.5.14) generates .key files... They are generally encrypted with wallet password and result in the random text starting with a 'U2' and ending with '='

Refer here: https://multibit.org/help/v0.5/help_exportingPrivateKeys.html

There is NO SEED for MultiBit Classic.

However, there is a seed for MultiBit HD, but that will generate a completely different wallet than the one containing the keys from MultiBit Classic.

OP, you need to establish if your coins were in MultiBit Classic or MultiBit HD. They are two different programs with different wallet formats.

If it was MultiBit Classic, do you know the wallet password for your MultiBit Classic wallet? If so, recovering the actual private keys from should be a relatively simple task.



OK thanks for that. Unfortunately can't find my password, though am still trying everything that I might have used back then.  Have an unencrypted backup file but don't know if that is of any help to me? If no seed for multibit classic, which it definitely is, what is the string of 12 words that I have??

Found password and exported private keys to a file. What now?Huh??

You can import them into Bitcoin Core. Or "sweep" them with Electrum. I think in this case I'd use Electrum.



OK tried sweeping into electrum. Entered private key from file but not allowing me to continue. Cancel button is available but not sweep button. Obviously doing something wrong but don't know what. Do I include # at start and end? Also tried JackG method, with same result.  Private key starts with L, is this expected?

L means it is a compressed key (https://en.bitcoin.it/wiki/List_of_address_prefixes).  Electrum can't import compressed keys (e.g. https://bitcointalk.org/index.php?topic=129661.msg1385022#msg1385022 & https://bitcointalk.org/index.php?topic=129652.0).  So, I suspect that is your problem.

You should be able to use the steps here to convert it and then import it:
https://bitcointalk.org/index.php?topic=1970345.msg19609200#msg19609200

I haven't tried it, but others have.  Make sure you do it off-line, and (as always) make sure your computer is not infected.





1226  Other / Archival / Re: Need help for my private key it was in 2013 on: September 03, 2017, 02:10:53 PM
No advancement for the moment, i do nothing in private i need help from the big community of bitcointalk

But if a Hero or a legendary want to that in private i'm ok

It is always better to do it in a message thread like this vs in private.  While many people are honest, there are enough who are not that it is better to be safe.

Can you please share the precise method of how to use electron cash and what's the trust level as I have heard that you may loose your BTC for unsuccessful attempt of getting access to Bitcoin Cash funds.

Thanks

1230  Bitcoin / Press / Re: [2017-08-31] Does bitcoin threaten economic stability? on: September 01, 2017, 07:23:11 PM
HONG KONG (Project Syndicate) —
...

There is no telling how far this trend will go. Technically, the supply of cryptocurrencies is infinite: bitcoin is capped at 21 million units, but this can be increased if a majority of “miners” (who add transaction records to the public ledger) agree.
...

Last year’s IMF report indicated that cryptocurrencies have already been used to circumvent exchange and capital controls in China, Cyprus, Greece, and Venezuela. For countries subject to political uncertainty or social unrest, cryptocurrencies offer an attractive mechanism of capital flight, exacerbating the difficulties of maintaining domestic financial stability.


Who writes some of this junk?  Miners can't agree to change the limit - sure they can fork the coin, but who is going to follow a coin that is (a) centralized to the miners and (b) subject to the whim of miners inflating value away.  They might as well trust a central bank.

As far as "maintaining domestic financial stability" - how about following a sound money policy instead of playing games with it?  Duh.
1231  Bitcoin / Bitcoin Technical Support / Re: I'm a journalist - I have 'lost' my Bitcoin - Requesting help on this story. on: September 01, 2017, 05:45:39 PM
I agree with what you said.  I wanted to make sure he was being precise in what he said as that could help to eliminate the possibilities where the error was made.  ;-)

I will be interested to see if he returns.

If your friend received that address from "his IR exchange in Australia", one would think it would be one of their addresses.  It doesn't make any sense that IR would be providing anyone an address for a different service such as Kraken.

I suspect that he means:

"My friend looked at his transaction history on IR to see where the bitcoins were sent to."

Not:

"My friend got an address from IR and then used that address to send the bitcoins to me."

When you asked "Where did your friend obtain the 1NxR3TLr1AXYYodX7EC2PVYqWL1XuQcC8m address", I think the OP didn't realize that you meant:

"How did your friend choose an address to send the bitcoins to?"

And instead accidentally thought that you meant:

"How did you determine that the address 1NxR3TLr1AXYYodX7EC2PVYqWL1XuQcC8m was the one you had used?"

If so, have you contacted IR support to see if it is one of their own addresses?   Of course, if he didn't really "receive it" from "his IR exchange" and instead used an address that he had previously sent bitcoin to from IR in error he would probably know who that was based on his transaction history at IR who that address belonged to.

These are possibilities, but I suspect that the more likely scenario is a mis-communiation between yourself and OP.

As DannyHamilton said above, something got messed up in one of the listed steps. It seems prudent to verify that the address "1NxR3TLr1AXYYodX7EC2PVYqWL1XuQcC8m" actually was provided by IR *or* whether it was something your friend had sent to previously, *or* if that address was changed by malware on either of your machines.

Yes.  The important question that ONLY the OP and his friend can answer is:

"What was communicated when you were getting ready to send the transaction, and where did that information come from?"

If it was provided by IR, why are they providing addresses for different services?

I doubt that they are.
1232  Bitcoin / Press / Re: [2017-09-01] F2Pool Reneges: Bitcoin Pool Pulls Segwit2x Support Over Hard Fork on: September 01, 2017, 05:42:07 PM
I reckon this is only the beginning. We may see more mining pools and miners pulling out from their support of the New York Agreement. To put it candidly, what gain does another hard fork present and is the risk worth the reward?



More transaction capacity per block. The real question is not, if a hard fork is worth the reward, but rather, which
chain gets the desired BTC ticker symbol at the exchanges.

Your fear of hard forks is unsubstantiated in my opinion, because smaller coins like Monero hard fork all the time
and it works fine, if the majority of the hashrate supports the forked chain.

Hard forks in general are problematic because they establish precedent that for a "good reason"(tm) as determined by someone else changes to the root protocol can be made at whim. 

Don't like the fact that someone made a coding error?  Roll it back and fork the coin.   "Distribution" isn't "fair"?  Fine, we'll change the rules to redistribute coins. 

Hard forks should be few and far between (if ever) because they are both poor precedent, seem to make a small group a single point of failure (e.g. a few individuals in control of mining pools) and can be dangerous to the stability of the coin.  Like TCP/IP, DNS etc, changes are extremely rare, rolled out with plenty of warning and extremely well tested.  The 2X portion of Segwit2X is even more problematic due to the speed of the rollout and testing issues.

1234  Bitcoin / Bitcoin Technical Support / Re: Restart/recover Wallet on MAC on: September 01, 2017, 02:19:33 PM
Thank you for this advice.
Unfortunately I only have a mac book. What other Software would run with electrum wallets?
Br

The easy answer if that is the case then is to go into System Preferences -> Users & Groups and then after you unlock (click the padlock icon) hit the "+" symbol and add a new user account.  Create a new account on the Mac Book.

Log in to your new user account and restore Electrum there.  One advantage to having it in a separate account (and making sure your regular one is "Standard" not "Admin") is that it provides a little isolation from the regular user account.


You should also be able to move the "default_wallet" to a new location then you could create a new one and restore it in your regular account.  (Or perhaps rename it - in ~user/.electrum  iirc. )

1236  Bitcoin / Development & Technical Discussion / Re: Fork After Withholding (FAW) Attack on Bitcoin on: September 01, 2017, 01:13:45 PM
Well, thanks for the information about this new attack, if it turns out to be valid.
I would like to ask you to spare us the worrying and tell us if there is an economical incentive for large mining pools not to cooperate with the rest of the network in mining or something similar, since possible attack isn't always the profitable attack.

We report to this forum, as there is no proper mechanism for vulnerability disclosure process in Bitcoin.
As long as I know, the attack has not been used in practice.
The attack is always profitable unlike selfish mining.
The attack is stealthy. The victim may notice that it is being attacked maybe due to higher fork rate, but it is hard to pinpoint the attacking pool or miner.

See:
Step 1. https://bitcoin.org/en/bitcoin-core/contribute/issues#disclosure  which leads to:
Step 2. https://bitcoincore.org/en/contact/

which is what you may have done - but there is a proper mechanism for people who look at this later.
1237  Bitcoin / Bitcoin Discussion / Re: Lighting Network and Segwit 2x newbie questions? on: September 01, 2017, 12:00:09 AM
Whats the latest with lightning now?

Also with the segwit 2x nya agreement does that mean it's a agreement in a contract meaning people who signed the contract cannot back out of it?

To me, the agreement reads like a memorandum of understanding,
see https://medium.com/@DCGco/bitcoin-scaling-agreement-at-consensus-2017-133521fe9a77

The NYA doesn't read like a typical contract with precise terms, requirements, dates, specific performance requirements etc.  That said, anyone can try to litigate anything and no doubt someone at some point will try.

But things like "We agree to immediately support the following parallel upgrades to the bitcoin protocol" are easy to say, okay, we did immediately support it. Now it has been a month so we didn't agree to continue to support it forever etc. Definitely wasn't drawn up with terms that I would rely on to be enforceable. 
1238  Other / Beginners & Help / Re: Why transactions takes so long? on: August 31, 2017, 11:01:17 PM
I don't know much about how BTC or ETH works, but why all cryptocurrencies takes so long to confirm a transaction. I think even 30s is too long, why cant it be instant like PayPal?

PayPal and credit cards can be reversed for MONTHS afterward. Bitcoin gets into the mempool across the network in < 1 second and it is very difficult to double spend thereafter.  Once bitcoin has several confirmations it is pretty much irreversible, certainly after 6.

So in a second, bitcoin is across the network. And in a few seconds on the paypal servers.
In an hour (if you paid reasonable fees), bitcoin is confirmed and can't be reversed. In a few months PayPal and credit cards are final and can't be reversed.

With segwit and lightning, Bitcoin is across the network in a second and micro transactions are easy. And it's confirmations will be as above.

All without relying one a third party who could block your account and remove your money - for any reason.

Tell me again which one takes a long time?

1239  Bitcoin / Press / Re: [2017-08-29] It Looks Like New Bitcoin Millionaires Are Avoiding the IRS on: August 30, 2017, 06:36:46 PM
Its impossible to engage the legacy banking system and not leave a trail. Just pay the 13 - 15% on long-term capital gains and be done with it. (Most people have held for more than a year.)

I don't understand why someone would risk potential fines and audits or even jail by not paying. Whatever your stance on taxation is, you're not going to change the system from inside a jail cell.

Agreed.

One open question is the impact of the Ver Tantrum Coin fork since it had/has some value.  The IRS hasn't given guidance yet as far as I am aware as to how to handle it.

When do you pay taxes:
1. At the fork?
2. Converting it from Ver Tantrum Coin to BTC?
3. Selling any resulting BTC?

Probably #2, but hopefully #3.

My limited understanding is that any real income is determined by local currency.

So the conversion from whatever crypto into fiat is the taxable event.

It could be more complicated, but until specific guidance is issued, you're better off paying something rather than nothing. It is in your favor to have had attempts to settle potential tax instead of avoiding it all together.



I like the edit.  Lol.

It does depend on jurisdiction, you are right. Some it could be conversion between cryptos and some just converting to fiat.   E.g.  If I have a yen position (and I am a US citizen) and trade it for the Euro for a gain, that would be a taxable event even if I don't convert to dollars for a week.  And was it short or long term gains?
1240  Bitcoin / Bitcoin Discussion / Re: A new bitcoin fork? on: August 30, 2017, 05:15:26 PM
Bitcoin GPU, also known as Bitcoin GOLD and BGOLD with the symbol BTG, is planning to fork off the main chain and use an ICO to “help BTG chain the longest Bitcoin Blockchain.”
“Bitcoin GPU is a full node implementation of the Bitcoin protocol,” its website, which curiously features the Bitcoin Cash logo, states.
“GPU mining can protect Bitcoin Key value: Decentralize.”
The first Bitcoin fork, Bitcoin Cash, has become sufficiently widespread to warrant regulatory involvement from the US Securities and Exchanges Commission as Bitcoin holders received duplicates of their original BTC holdings.

Once forked from block number 478558, the assumption from commentators is that balances will double again, creating what trader Vortex refers to as “more free money.”

"first Bitcoin fork"?  Oh please. There have been many.

"en-crease" Huh

"Block 478558", so it already happened and will be live 16000 blocks after that?  We are at block 482670. 

It will change the bitcoin POW?

Binaries but the link to source doesn't work?

Seems scammy and sketchy so far.
