I do not know about the others, but personally I prefer the One model - it is physically smaller and fits in my wallet. As a functionality for MAID, both models use the same user interface and there is no difference for the end user.
The problem is not in the Trezor itself - the last two cases, for example, @Southside did not know that in order for MAID’s user interface to be active, you must have MAID in your wallet, and with @Luis_Gonzalez_Alvare the problem is most likely in his computer…
Therefore, I continue to recommend anyone with more than $ 1000 in crypto to get a hardware wallet, because when working with their crypto it will not endanger it as with a hot wallet, and also as a user experience it is easier.
Is the general consensus that it’s better to store on trezor vs a paper wallet. I’m considering making the switch but seems several people are encountering issues. Not sure if it’s worth the possible issues. @Dimitar what’s your thoughts - I think plain sailing for you storing on Trezor? .
Do I want to make a new cold wallet every time I move MAID? And what if tomorrow the token is $ 10? Will I take risks every time?
The hardware wallet is equal to a cold wallet from which you can move small amounts without compromising the security of the entire amount.
An isolated environment with a separate screen, which guarantees that even if your computer is compromised and you send money to the “wrong” place, you will be able to see it on the screen of the Trezor.
This is all true. But I still have not made the decision to my my MAID to my Trezor, because of the fixed transfer fee of 8000 satoshi. I think this is a fundamental problem in the OmniTrezor wallet. What if the BTC mempool is so full that 8000 satoshi is not enough to transfer in the next block? Then your transaction gets perhaps stuck for days…
The fixed transfer fee should be changed to a customizable fee before I want to send my MAID to Trezor. But please correct me if I’m wrong…
The issues encountered really aren’t a big deal. Once you learn how to do it, thanks to Dimitar’s tutoring here, it’s not any more difficult than learning to utilize a paper wallet.
The fee is not fixed, 8000 satoshi is the minimum. It calculates it automatically according to the network load. It is currently offering to send MAID for 113400 satoshi:
Ah ok, that’s a lot better.
Still having doubts how this is calculated, because this fee is about EUR 5,50 at current prices while the mempool does not seem to be very high.
However, this is only a small cost compared to the added Trezor security. I might rethink my strategy and put half my MAID on the Trezor.
Thanks for the info!
I’ll be honest, I’ve never used trezor so I’m not familiar, but the article states they needed to brute force a pin which can be 1 - 9 digits long.
I know the more digits the harder to brute force, so odd you can’t have a longer than 9 digit pin which certainly would mitigate the attack, but from reading the article I assumed 9 digits was the max you could have.
Edit.
According to this link, 9 digits will take apx 5 days where as a few more digits will take apx 200 years.
Have you looked further into this? If I’m reading these articles correctly, the Kraken hack can get the seed, and then you would brute force the passphrase. This means checking a balance at the address on each attempt which slows things down, but maybe not that much for a full node.
I see the table Trezor give which suggests a decent passphrase is costly to crack, but I’m not sure how valid that is. I have the impression that brute force crackers are very efficient. You are encouraged to use something you can remember such as a meaningful phrase rather than random characters, so in practice I’m not sure how secure different passphrase choices might be.
Anyone know more about this area care to comment (@mav)?
Overall the passphrase approach itself looks very useful - reading the Trezor explanation of passphrases is worthwhile to see why. It might seem like an extra hassle ensuring you don’t lose or forget it, but using multiple passphrases to have multiple wallets is neat.
Note that the passphrase is not the PIN, it is an actual passphrase in addition to the PIN: Passphrase - Trezor Wiki
any character or set of characters, a word, or a sentence up to 50 bytes long
You have to brute force the PIN and then the passphrase before you could get to the all important seed that those two security barriers are protecting (as far as I have read).
See the table under “How to choose a good passphrase?”. 6 random words is more than enough to secure against this complicated physical attack (as well as being simple, easy to remember). Make as many permutations as you like to effectively have as many wallets as you like, decoy wallets etc.
I might rethink my strategy and put half my MAID on the Trezor.
