Quite a short "review" that left a lot of blanks. Fortunately replies to that article filled in some of them.

Case Wallet Review

https://www.youtube.com/watch?v=NeQMgarnZIk


pricey and it looks not very good for that price...  Roll Eyes

Except the old adage applies, "if you don't own your keys, you don't own the bitcoin". They still hold a key, what happens when the company disappears?

I really want to know if choosecase is real, it suppose to ship on Sept 21,2015. I wanted to preorder, but was very cautious of bitcoin hardware preorders.  Tongue

What happens when Case goes out of business? 2 of your 3 keys are gone.

New email from coolwallet.


New Campaign Update!
Hello kkurtmann,
The ‘CoolWallet - most convenient Bitcoin cold wallet’ team just posted:

1 new Announcement:

Dear backers,
We now estimate to deliver in the middle of August. There were tiny things that took longer than we expected.

Here is the progress update:

Our CoolWallet card has been optimized; with watchdog mode on, the battery can last for more than 90 hours.

CoolWalet app is being reviewed by Apple.

We are constantly testing CoolWallet to ensure the best stability.

We will dispatch the goods once our app is up on the shelf and test result is satisfying.
Thank you for your patience.
CoolBitX Team

Good thing I only contributed 5 bux.

I am now back on my ledger as it is working and my trezor doesn't5 work now (its not recognised). Ledger has been more consistent and always let me use it. the only problem was when it came to spending bitcoin I needed my card as my linked phone app didn't show the transaction to accept. But now trezor I cant do anything. So Ledger has been the best for me so far Smiley But I do like the trezor too. All these problems for both will be fixed though. I guess we have to have these problems in order to overcome them.


Try a different usb cable with the Trezor. The cable it ships with is a known issue.

Extracting the Private Key from a TREZOR

http://johoe.mooo.com/trezor-power-analysis/

Big respect !

Do you think that this HW wallet is more protected ?
www.eliptibox.com


according to them, yes

according to me, I don't know, because nothing is published yet


Them and coolwallet both look promising, but seems like nothing is happening.

does Mycelium give the option to input Trezor 24 word seeds for recovery?  the default Mycelium seed is 12 words.

And passphrase too?

Nice streak again!

Out of curiosity, do you guys split your hashes over different pools?  I have about half on Slush and half on BTC Guild for now.  I did like the consistently of Antpool (in terms of blocks being found), but with all of the DDoS issues they have been having recently, I've been staying way.
If by splitting on one device? No.
I just set backup pools incase one or two have problems...


I have 4 s3s on slush's and 4 s3s  on kano's. Seems to be working out so far.

Which pool has paid more since you started this method?

Why not just print out the possible words, number them and select 24 of them by coin-flipping or using dice?

I lost you there... could you please elaborate? How would i integrate checksum?

good point. I was a bit naive and thought any combination of words would be a valid passphrase. I'm not sure this is the case.

Although using a mnemonic not generated by the algorithm described in "Generating the mnemonic" section is possible, this is not advised and software must compute a checksum for the mnemonic sentence using a wordlist and issue a warning if it is invalid.

Not sure how trezor handles this.

There is no checksum in seed, any combination of words (of bip39 list) is just fine as long as they are truly random and not chosen by a human brain.

I think my brain is random enough.

what is up with the mytrezor page having captchas now?  Is that normal?   Today is the first time I have seen that...

no captcha for me on mytezor.com.

slush pool site has had captchas for a long time though.

New miner here, Slush is definitely on a roll now!  

I'm sure it all evens out in the end for the most part though, but it's fun watching all of these blocks being found in such short order

You are one of the most informed newbies I have seen on here in years.

He must be from the Midwest  Cheesy

Haha I can't tell if you guys are sarcastic or serious, hopefully the latter.  But I am definitely liking Slush's new website and all of the data it has compared to a few other pools I looked at.

I was serious.

I just started mining but been adding S3+'s, S5's and Sp20's to my rig. Still a baby setup compare dot you guys though. LOL

I do have to chime in though, I don't see the possibility of a 0.03-0.05 watt / GH possibility. Even if it's in a 100Th setup. No way, no how, with today's technology.
Only way is to do a hybrid of alternate Energy + grid power.


I'm pretty sure he was talking about the supposed next gen 16 nm or smaller technology as per the efficiency quote.

Still. I somehow doubt they have more efficient engineers than Intel or ATI/AMD, IBM, and even they have not reached such low power figures.

I just don't see it.. This next gen releases will probably be in the 0.30W/GH power figure, maybe high 20's if they really get some good dies made.

Besides if that becomes true. It will highly impact the BC Mining world and I don't think in a good way for smaller miners.  Grin

Well, KnC miner claims achieving 0.07 w/GHs for their new 16nm on their website here https://www.kncminer.com/news/news-118 . I'm sure other manufacturers will make the same or better claims. This is old news that companies have been working on this, but I'm pretty sure there won't be any physical devices until the end of this year at the earliest.

There is a new wallet concept - http://www.eliptibox.com/. First to talk about firewall on hardware and packed with features.
Can be interesting platform for developers.


Interesting concept, thanks for sharing. What does "fpga hardware firewall" means? Why do you need this if you do only offline signing? I don't assume that this wallet downloads the blockchain to let you view your transactions.

I also was wondering why a field programable gate array would be used as a firewall. Apparently it does download block headers and stores tx info on the device, so says their site.
