I never invested in DAO so someone else will hopefully give you the answer you need sorry about that. I do know that if you update your local ether wallet (Mist) to latest you will be given the opportunity to follow the fork and DAO funds will be released for withdraw as post fork Ether. I would hold off until someone else chimes in though.
2142  Bitcoin / Hardware wallets / Re: [ESHOP launched] Trezor: Bitcoin hardware wallet on: August 02, 2016, 03:18:39 PM
Price of Trezor was increased temporarily due to short stock it seems but price is back down to $99 at https://www.buytrezor.com/ add $10 for standard shipping. With the new Ledger Nano S selling for 61.62€ (69$) with ground shipping included I doubt Trezor could ever justify charging more than $99 again, the competition is too good now. Anyone looking at both hardware wallets will see they can save about $40 and have hardware storage for both Ether and Bitcoin with the Nano S. Competition is good for the consumer.

Yes, it's good. But I prefer Trezor security to be honest. I don't see much problem on paying $40 or $50 more for a device that has more reputation over the bitcoin space.

If you hold Ether or Ether Classic as well as Bitcoin the Nano S is your only choice for a hardware wallet for all three coins. Nano S has a significant security improvement over Trezor if you need to recover the device to a new one: unlike Trezor, the seed for Nano S is only ever displayed on the device itself, not the host computer. The seed is never leaked at all. I have been using Trezors for years but have to admit the Nano S is next generation. It will be interesting to see what Trezor 2.0 can do.

This argument is a moot point. From trezor's faq section:

Quote
What if I run the TREZOR recovery process on an infected computer?

During the TREZOR recovery process you are asked to enter your recovery seed into the computer with the words in a random order. By default, the TREZOR uses a 24 word recovery seed.

If your computer has a keylogger installed on it, then the randomly ordered words may be stolen. One might try to re-arrange these words, until they found the correct word ordering. They can check the order of the words, by generating a bitcoin address using each ordering and checking if the address belongs to you.

There are 24! possible orderings of a 24 word seed. That is 620448401733239439360000 possible orderings.

Each 24 word TREZOR recovery seed is verified with an 8 bit checksum . Using the checksum to eliminate invalid seeds, you can reduce the search space by a factor of 256. This gives us a search space of:

24! ÷ 256 = 2423626569270466560000

Going from TREZOR recovery seed to public bitcoin address takes 2 × 2048 iterations of PBKDF2, which in turn uses SHA-512. All in all, going from a potential TREZOR recovery seed to a bitcoin address, is slightly more difficult than running SHA-512 8096 times.

To summarise, in order to check all possible orderings in a 24 word seed, you need to run SHA-512:

24! ÷ 256 × 8096 = 19621680704813697269760000 times

The bitcoin network is capable of preforming 176 537 883 000 000 000 iterations of SHA-256 each second.

If we wave our hands a bit, we can claim that SHA-512 and SHA-256 are the same difficulty (which they aren’t but let’s pretend they are). Therefore, it should take somewhere around half of:

(24! ÷ 256 × 8096) ÷ 176 537 883 000 000 000 ÷ 60 ÷ 60 ÷ 24 ÷ 365 = 3.5 years

for the ENTIRE BITCOIN NETWORK to crack the seed. If you have that kind of hashing power, you’d make better money mining at Slush Pool than trying to steal bitcoins. :-) On a normal botnet cracking a TREZOR seed would take millenia.


What is not easy to do today may be trivial in a few years. KeepKey made a fuss about how their rotating cipher leaked less info than Trezor on recovery. Well, Ledger just upped the ante with the Nano S which leaks nothing on recovery.

I believe all you have to do is send your ETH to Polo and they will credit you with the same amount of ETC as long as you have not updated your Ethereum wallet to follow the fork.

2145  Alternate cryptocurrencies / Altcoin Discussion / Re: The only and ONLY way that Ethereum can survive is throught ETC on: August 01, 2016, 06:22:36 PM
If you look at trade volumes most ETC is being bought with bitcoin rather than ether ten to one. So bitcoin users are the main supporters of ETC. Ethereum chain state shows miner interest in ETC growing as ETC is still more profitable to mine than ETH. I think the real test is if the ETC/BTC price high of .004872 is taken out things could get very interesting.

People who lose bitcoin to a thief from a desktop wallet are usually victims of bitcoin trojans that capture your password from keystrokes. That is where hardware wallets come in.

You think that using a mixer for your bitcoins will keep your identity safe?
Think again! It has been proven that this is false.

Anyone can make a statement can you back that up with links to articles or academic papers that prove your point?

A problem no one talks about much concerning mixing services is it is suspected that the largest volume clients on popular mixers are drug dealers tumbling their coins. In effect drug dealers are exchanging their coins for coins that were deposited by other dealers.

So if you are using a popular mixing service to mix gambling proceeds you may get coins sent back to you that trace back to a darknet drug market. That might raise a red flag at a service like Coinbase.

You might consider using a more private way of mixing your coins using Monero.
2150  Bitcoin / Electrum / Re: Electrum and TOR on: July 30, 2016, 08:13:59 PM
If you are concerned about Tor just use Electrum over a good VPN so your true IP is never logged by Electrum servers. Another option would be to connect to your VPN first then start Tor Browser and then configure Electrum to connect by Tor:

Go to network settings, and select:
Protocol: SSL
Proxy: SOCKS5 127.0.0.1 9150

There are also serveral Electrum servers with .onion addresses like electrum-server.ninja. Connecting by VPN first hides your use of Tor from your ISP if your provider is one of those who dislike Tor.
2151  Bitcoin / Hardware wallets / Re: OVERVIEW: BITCOIN HARDWARE WALLETS █████████████████ Secure your Coins on: July 30, 2016, 07:29:10 PM

I have purchased the Ledger cheapest one but the material looks very cheap, is the Nano S a strong material, do you have any idea if it is water resistant!
Ether support is increasing time by time and ledger nano S being the first ethereum hardware wallet makes the ledger more usable!

The new Nano S is substantial. Nor sure what type of plastic the case is made of but the body measures slightly over a quarter inch thick. I doubt dropping it would break it. No idea on water resistance sorry. I suspect the USB port would be the problem with water. This hardware wallet impresses as a very well made product.
2152  Bitcoin / Hardware wallets / Re: OVERVIEW: BITCOIN HARDWARE WALLETS █████████████████ Secure your Coins on: July 30, 2016, 06:03:10 PM

2153  Alternate cryptocurrencies / Altcoin Discussion / Re: ETHf - forked eth has to do another fork on: July 30, 2016, 05:58:20 PM
The hard fork was rushed due to time constraints and I think the Ether devs did not expect ETC to survive this long. If they did they would have taken more care to sever the chains properly.

ETC will not hard fork, so Ether has to hope that miners on ETC move back to Ether. Right now Ethereum Chain State shows ETC hashing power down to 500 from 600 gH/s yesterday. Give it a few weeks, I think ETC hashrate will either be down to less than 100 gh or up to 1000 gh/s. If that happens Ether may be forced to hard fork again.

now i have three options . spectrocoin, advcash and  shakepay. the wirexapp gave contradictory and unsatisfactory answers.

all these are really do not want any documents or verification?? I'm looking some card same like you and do not want to share my documents too. In addition, do not want to answer stupid and unnecessary questions.

You can get a plastic AdvCash without verification but limits are lower http://advcash.com/en/
2157  Bitcoin / Hardware wallets / Re: [ESHOP launched] Trezor: Bitcoin hardware wallet on: July 26, 2016, 10:57:56 PM
Any idea of when the Trezor 2 will come out? I'm super-intrested in it. I can't afford to go to Prague to test it, either. But i'm guessing early 2017?

stickac said on reddit that 2.0 will not be released sooner than the end of this year.
2158  Alternate cryptocurrencies / Altcoin Discussion / Re: Ethereum Wallet update from 7.2 to 8.1 on: July 26, 2016, 05:29:35 PM
Ok, but I have Ether in my 7.2 wallet. What about that?

Please help me  Undecided

You will still have that Ether when you update. Backup your keystore before you upgrade on the off chance there is a glitch.
2159  Alternate cryptocurrencies / Altcoin Discussion / Re: WHo will win - ETH or ETC? on: July 26, 2016, 05:21:44 PM
You can follow the hash rate for both chains at http://fork.ethstats.net/

Right now Ether Classic is the most profitable coin to mine using GPU https://www.whattomine.com/
2160  Alternate cryptocurrencies / Altcoin Discussion / Re: Ethereum Wallet update from 7.2 to 8.1 on: July 26, 2016, 05:19:01 PM
Download latest 0.8.1 here https://github.com/ethereum/mist/releases

Just start the application using the icon in the folder, you will be asked if you want to fork or not fork. Most will probably accept the fork. You cannot maintain ether wallets for both chains on the same computer.
