@HI-TEC99 already suggested you post the txids
1722  Bitcoin / Bitcoin Discussion / Re: If the Winkelvoss ETF is approved, how/when are they open for business? on: March 06, 2017, 10:26:57 PM
How long it takes COIN to get listed if approved is really up to the BATS exchange.
1723  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: March 06, 2017, 10:24:22 PM
You can use a Trezor with Electrum. If you are going to use a local bitcoin wallet like Core that does not support hardware wallets YET use a real good password.


Okay, one more question, why should I combine Trevor with electrum?

I thought only online wallets such as blockchaininfo wallet are vulnerable to hackers.
I thought that Electrum wallet is not possible to be hacked (if yes, how?).

Any wallet that exposes your private keys can be hacked. Keylogger malware can steal your password or a trojan could substitute a different bitcoin address. Bitcoin Core is still the most private way to use bitcoin but it is ultimately not as secure as a hardware wallet. The most secure way to use Bitcoin Core is to run Armory on top of it in cold storage mode. Needs two computers one always offline for the Armory wallet with private keys.

Can someone explain we what is going on? For the last few days everyone was talking about EFT, but today from few hours you are talking about some "BU", "Antpool", "pool"and other stuff. I'm pretty new in BTC and I don't understand what you are taking about, could someone help me?

I wouldn't know how to summarize or distill it further as you have to be somewhat familiar with bitcoin to grasp it. Bottom line if you are a new user. You are safe if you keep your coins off online wallets and exchanges as this blows over. Secure them in Hard ware wallets if you can or an offline computer.

Why do you recommend this ? Some people are here to trade and invest and buy-sell- sell-buy... why if i have coins to the exchange i maybe have problem?
( don't tell me is not safe like gox we all know that but it's the price to pay if something happen in case of hacker - or government Smiley we know that, at least we took a lesson with gox )

but what this have to do?

It is all about having options. If there is an imminent hard fork you want to have possession of your private keys as you have more options. The safest most private way is to run a Bitcoin Core node on a home computer. Second would be a hardware wallet like Trezor or Ledger Nano S.
1726  Bitcoin / Bitcoin Discussion / Re: Are transaction accelerators a better option than segwit or lightning network on: March 06, 2017, 09:25:35 PM
I have seen people using accelerators to help their unconfirmed transactions get through.

This seems like it could be a better option than segwit or lightning network.

What do people think about this?

You are better off using a wallet like Electrum on your computer or phone. Enable dynamic fees and replace by fee, and mark a transaction as replaceable when you send. Also set the fee slider to high. If for some reason the dynamic fee calculation is too low and it is taking longer than an hour for your send to get confirmed, just click on the transaction in your wallet and bump the fee up.

Acutally if a hostile fork happens then almost the whole network will reject the invalid blocks  Huh  
They could fuck up bitcoin really bad.

Yes,  91% of nodes will reject BU blocks and ban all nodes relaying them -

Jihan is either bluffing to renegotiate (not going to happen) or he is serious and hoping that 91% of nodes will suddenly switch to BU (also not going to happen)

There are 32610 Core nodes on the network ? How this Nr is measured ?

Is https://bitnodes.21.co/nodes/ more reliable?

SilverWallets has the right idea. Sell the coin unfunded with hologram provided and let the buyer generate the key pair and assemble the coin themselves. Likewise Polymerbit.

I would have to disagree with you. The whole point of physical bitcoins is that they are easily exchanged from one person to another, knowing that if the hologram or whatever is intact, they contain the face value of Bitcoin. If you let the "buyer" generate the private key, then later sell the physical coin, you have to trust the initial buyer didn't copy the private key. If this was the model from the get go, I believe you would see widespread individual sweeping of coins. You have to put trust in one entity, like Casascius.

Edit; in my opinion, the only "truly" trusted physicals at this point is OpenDime. Where the person loading the BTC never sees the private key.

Physical bitcoins in coin form are a novelty for bitcoin geeks (like me) and never had a chance of going mainstream. OpenDime has no collector appeal.
1730  Economy / Speculation / Re: ETF speculation: How has the SEC behaved in similar situations? on: March 06, 2017, 05:12:30 PM
From memory I can tell you decisions have usually come a few days before the deadline so Wednesday would be key I think. It would be a first if no official announcement is made and COIN is approved by default when the March 13 deadline passes.
1731  Economy / Speculation / Re: Price will not crash if the ETF is rejected on: March 06, 2017, 05:08:08 PM
The market has to some extent priced in approval of the ETF. Not very wise but that is how markets work. If COIN is denied you can count on a correction, probably an ABC correction to $900 - $1000 which presents a buying opportunity. Anyone who thinks traders will shrug off disapproval is naive.

If there is a pre-announcement in 3 days when would you be able to invest in it, immediately, weeks, months?

If @marcus_of_augustus is right the play is to buy bitcoin now. It takes time after approval for paperwork etc for COIN to be listed on BATS. I have seen estimates of about a month soonest after approval.
1734  Economy / Service Discussion / Re: How to get around Coinbase ban if you withdraw from (gambling) website on: March 05, 2017, 08:30:02 PM
Many have speculated that Coinbase can track transactions easily for four to five hops. That would make the local wallet trick null and void. Now, they may only be checking 1-2 hops now but that could change at any time.
1735  Economy / Collectibles / Re: Alitin Mint Adam Smith Coins compromised! on: March 05, 2017, 07:41:03 PM
Sorry for your loss. This is why I have never bought any funded physical bitcoins though I have been tempted.
1736  Bitcoin / Electrum / Re: Highest dynamic fee not high enough on: March 05, 2017, 06:40:56 PM
Thanks for the tip.
1737  Economy / Speculation / Re: Nights Watch by Afrikoin on: March 05, 2017, 06:35:20 PM
There are multiple overlapping Fibonacci resistance levels at $1026 on Bitstamp. That would be a $272 drop from the present ATH of $1298 which would not be unusual for a bitcoin bad day. The news would have to be bad enough to drop the price through heavy resistance at $1140 - $1163. Have to wait and see if the ETF is denied and what affect that has.
1738  Economy / Service Discussion / Re: Is viabtc transaction accelerator really working? on: March 05, 2017, 04:25:02 PM
I tried viabtc a few days ago after waiting for a withdrawal to my account. Initially, I can see thru blockchain that my it is still no confirmation so I panicked because I'm been waiting for it for at least 8 hrs ago. So I used viabtc to try to see if it works. I did like 3x on its website and on the 4th try it says its already confirmed so I went on my wallet and the bitcoin is already in it. So I guess it really works and will try to use on my next stuck transactions.

You should not have stuck transactions if you use a wallet that has good dynamic fees like Electrum. Just set the fee slider to high.
1739  Economy / Service Discussion / Re: Is viabtc transaction accelerator really working? on: March 05, 2017, 03:58:53 PM
It certainly works. They have been rate limiting it so it can be hard to get your transaction accepted. Some other pools that support SegWit should offer the same service. If you use latest Electrum with RBF and dynamic fees enabled you will not need it. If you send replaceable you can always bump the fee up yourself.
1740  Alternate cryptocurrencies / Altcoin Discussion / Re: Heavy invesment in Dash close to 2000 coins on: March 05, 2017, 05:10:05 AM
Dude this is the fourth time Dash has been pumped the difference is the price is twice as high. You should sell now and hold bitcoin, you made a good trade take the profits and run. You are much safer holding bitcoin than Dash, hope you can see why and the dollar signs have not blinded you. Monero pumped last September and the smart money got out at the top or on the dead cat bounce.
