Topic: OVERVIEW: BITCOIN HARDWARE WALLETS █████████████████ Secure your Coins - page 21. (Read 122206 times)

I tried still not working so they asked me to send back to them which I am doing

Has anyone gotten a B wallet from coinCola?, I'm looking to buy a few of these to give out to my family and friends so they could experience a hardware wallet.

yea, try a few cables, i guess i was lucky to receive a good cable ^^

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

a good investment i think.  

trezor and ledger are my favourites too.

I've invested in a trezor and i can say that it was really a good deal. security-wise, it seems that every single detail has been thought of.

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 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.

I like my trezor 

True but if we want to send raw transactions via QR code, it is not that hard but still not good. Wallet can split the transactions into a few parts and merge those after reading QR codes.

in my opinion it's a big liability, both for the manufacturer and the users. Amazon still has issues to get international coverage right with Whispernet, and that's Amazon, not a random startup. The day somebody somewhere has a commercial disagreement with a carrier, your device stops working and there's nothing you can do.


Definitely not in a convenient way. If you want a trustless hardware wallet, it has to stream raw unspent transactions to get the amount spent and fees right. Doing that over QR codes would clearly be a UX nightmare. Also tapping a card is faster than scanning a QR code if paying on a dedicated terminal.

I personally like Ledger the best out of all currently released hardware wallets

With the exception of the proposed built-in currency exchange function, Case seems to operate in a similar fashion to GreenAddress/GreenBits on an Android phone.

They hold one key, you hold the other, and yours is never sent/known by them but is stored encrypted locally and validated by you somehow (with Case the fingerprint scanner, with Green your passcode (or HW.1/Ledger).  And like GreenAddress, you also have the option to add a third signature that you control.

With Green, you have recourse in case GreenAddress disappears off the face of the Earth, with the Nlocktime auto-expire feature. I wonder if Case will have a similar feature?

I do sortof like the idea of built-in GSM for convenience and mass-adoption by non-techie grandmas and such.  That sounds neat, but is also another thing to "track" ones movements, I guess.  You can always pull the battery from your cell phone, but can you be sure your Case is off?  I guess there is some degree of trust required when using their device.

So far I am liking the CoolWallet design the best, but IMO it needs to lose the bluetooth/NFC communications stuff.  All we really need in a trust-free secure and simple HW wallet is a device with a screen, a camera, and a button and nothing else.  All necessary communication can be done by QR codes.

Please contact support with a precise description of your problem and logs if you didn't already.

If you did PM me the reference.

Well... It is so bacd now that I have resorted back to my trezor until the problems the problems are fixrd

PM if anyone wants to sell any hardware wallets.

just get in touch with support if you didn't already, we are tracking some issue with disappearing settings, should be fixed shortly.

and of course you'll be ok, no doubts about that.

There is me saying how good ledger is and just now its unusable due to pairing issues with my phone. I suppose all of them will have slight glitches. This is why I went from Trezor to ledger... Just makes me worried about keeping a lot of bitcoin on these things even with the recovery phrase... Anyway I am sure it will be ok :-)

I haven't had the time yet to test it myself, but it should function correctly (though not very user friendly).

Have a look at the nxt forum thread: https://nxtforum.org/index.php?topic=4550.msg171812#msg171812

Source code repository is here: https://bitbucket.org/blackyblack/trezor-mcu-nxt

they do, there are just not a lot of people adding support for it. It'll likely get better when our Electrum issues on Windows are fixed.

Case has a price - $199 and they had a limited amount for sale.
