I am still not crystal clear on certain things re Opendime devices and sending out any balance from the Opendime to another wallet.  Main Opendime thread here:

https://bitcointalk.org/index.php?topic=1452987.0

I have test-fired the Opendime, and it works as advertised.  In particular, I used an (old) blockchain.info wallet to "sweep" (importing the private key on the device) my Opendime balance to the blockchain wallet, and that worked OK.

However, my understanding is that the newer HD wallets will not allow importing private keys.  That's a problem for me should I want to buy and use (say giving away, etc.) Opendimes and use HD wallets...

Nor have I figured out if there is any way to import private keys into a Ledger Nano (about two years old) or Trezor (two years old).



Also, would paper wallets have the same issues?  


Thanks!  :)

before you break the seal/clip in the middle, opendime acts like a bearer bond. a watch only address to see the balance so that whoever handles it can see how much value is stored.. and able to add more funds to..

as long as the seal/clip is not broke getting the private key is not straight forward(not usually possible without a hack) which is the point. its not meant to be used as a hardware wallet for multiple things.. its meant to lock in ONE private key to add funds publicly as much as you like.... but only spendable once

the point of the opendime is not to sweep the key out, move funds and then reuse that key/opendime again.
its a one use device

if you want things like multiple uses and deterministic keys, then opendime is not for you.

however, i think that wallet/services should not limit the variety of privatekey/seed types they accept. but each wallet usually has a specific purpose and so they prefer to only handle certain private key creation methods depending on that purpose. and in cases where a wallet does have a specific reason. then its acceptable.(but we both agree it can be annoying)

in my view i would suggest using something like blockchain.info to sweep the opendime device and then move the funds to an address that you prefer by spending them to a destination address that is based on a private key creation method you do like.

its annoying. but then best security practices are that if multiple locations have a private key stored, EG opendime, followed by your computer when you copy and pasted, followed by blockchain.info.. its more safe to 'spend' the funds to a new key as the old key wold be considered compromised.
