I am familiar with using Trezor hardware wallet but I keep hearing about Armory.

Can anyone tell me would it be safer or what would be the advantage in me using Armory to store bitcoins if I already own a Trezor?

I dont want to hijack this but there is no place else to ask about this and this is the closest thing to the official trezor topic area I can find. I want to know if it is really safe to use the my trezor website to add my coins. They recomend you to this site to setu your trezor wallet and it seems like the only way to interface the coins and the wallet. I have alot of coins so I am nervous. I never used the online type wallets beause I dont trust them. I have used electrum and multibit and they have been good. But I do not want to trust my coins to some people in a website. I think I am missing something here but can can anyone help my ignorance?

If you are thinking about investing in a KeepKey - hold off. I plugged mine in the morning to review the overnight mining returns and left the device connected to my computer. Thirteen hours later, I returned to find the screen dark. No problem, right? Unplug it and replug it? Nope. When I picked up the device to unplug it, it was hot to the touch. I unplugged it and re-plugged it. No display. The chrome wallet flashed my balance for a moment or two (the keys are likely intact, I suspect) - but then it flashed the 'No Device Connected' message. I let the device cool down to room temps before trying again - same thing, no dice. Different computer with a fresh install of the wallet and proxy? Same thing. I've opened a ticket, and DM'd the owner/developer and am waiting for a response. Googling the problem yields nothing (the device is brand new and somewhat expensive so I'm sure there aren't that many in the wild).

Breadwallet ceo:

RVC: I've read that mobile wallets should only be used for pocket change. How much money can I safely keep on my phone at one time?

It's ironic, because many people don't realize that their smartphones are actually the most secure computing device they own, far more secure than desktop or laptop systems. It's wallets that can be accessed from the web or desktop that should really only be used for pocket change.

An iPhone uses the same techniques of app sandboxing and enforced code signatures that dedicated hardware wallets use. The phone is also hardware encrypted so your funds are strongly protected even if it's physically stolen. The US DOJ even complains publicly that the phones are too secure. Some people prefer to keep large amounts in paper wallets, but for someone who doesn't have a strong technical knowledge of bitcoin, misunderstanding how change addresses work can result in total loss, so they're not really suitable for the general public. There was recently a $1M dollar bounty offered for a remote jailbreak of iOS, and the winner ended up having to use an exploit in the chrome app, so if we assume markets are efficient, then in theory it should be safe to keep at least $1M in breadwallet (if you don't use chrome).

IMO all hardware wallets are much too new and untested for it to be a good idea to store large amount of bitcoin on them.

Users with a more of an advanced understanding of Bitcoin should be able to audit any address they are told to send to based on the seed, as well as any change address it will send to as part of a transaction. Although the trezor seems to be marketed more towards more novice users. (they can audit based on the seed which can be used to calculate the xpubkey).

The risk with the trezor is that it is really not known how resilient to attacks it will be in the event that an attacker were to come into physical possession of the trezor. I believe that some security researchers have been able to detect radio waves from a trezor without inputting valid credentials, which could, at least in theory, lead to the private keys the trezor is suppose to be keeping private.

Another, probably more realistic risk for most users is that (AFAIK), even with the seed, you need to use a trezor in order to spend any BTC that is stored on the trezor. This means that if their trezor were to malfunction or break, that the user would need to wait until they can purchase a new trezor, and until it arrives to be able to spend the BTC they are trusting it with, and this is assuming they make proper backups of their seed.

I would personally suggest using electrum for both your cold and hot wallets (at least for your hot wallet on your computer). It takes up very little resources, is deterministic, and has all the same features that armory has. Also you will have greater control over when your private keys will potentially be vulnerable -- if you are using full disk encryption and a strong passphrase for both the wallet file and to decrypt your harddrive, then your private keys will be minimally vulnerable while your computer is "on" and will be fully exposes for the few seconds (if that) that your private key is in ram; if you are not sure that you will be able to fully power off your computer after decrypting your wallet, then you simply should not decrypt your wallet to sign a tx. Plus I believe it is possible to calculate the private keys based on the seed in the event that you do not have access to a copy of electrum.

Still no luck as I've tried to update.  I've started the process about 8 times here in my office (with a fine signal on my GSM phone, no way of checking how the signal is according to the device) but every time it's gotten less than half way before seeming shutting off.

Dear deleloper team!

I see know strange case. I cannot find your MyTrezor application in Android's store
FRom computer i see "We're sorry, the requested URL was not found on this server."

https://play.google.com/store/apps/details?id=com.satoshilabs.btcreceive

And i cannot find the MyTrezor application from my Android phone

Can you write what happens?

24 hours initialization? Come on? Why the hell? Why can't you just use public bitcoin servers? Why do I have to have 40 GB of junk on my hard drive? Every user is supposed to host this shit at his PC? Why the hell? Do you know what networks and internet are for? And then? "Building databases message forever. No CPU activity, no drive activity. Try to kill it? "Preparing to shutdown" message forever. Come on, guys? Did somebody ever test this? This crap is supposed to manage my money?

Yes I am in a similar situation. I attempt to update it, but it refuses. I was hoping last night it was due to a large load so many upgrading and all, but seems not.

I am getting more and more concerned as the issues continue and the lack of a true 2 of 3 multisig is used. I say lack of a true 2 of 3 because without case servers you really only have 1 key. There is no way to currently get a key off a device or use it in any useful format without the case servers.

hi guys, i am new in bitcoin world, I interested in mining but some reasons i can't start easily. My best option is cloud mining i am currently registered in www.hashnest.com but i did not yet investing. can anyone try this website?

I'm afraid to be a victim of scam.

please share your knowledge about that website i plan to mine.

or anybody can offer the best cloud mining website.
