Can Hempcoin be stored on a Trezor? What is the best way to store Hempcoin so it can be taken off an exchange for safe keeping?
Coinomi has a mobile wallet for THC for every day use. You could try a paper wallet for long term storage.
Thanks
This is how Coinbase explains how to backup on paper with alt coins, below, granted it seems to be for Windows and not any other OS (what to do for iOS?) Is this advisable for Hempcoin, below?
"Exporting private keys from altcoin wallets
If you want to create a paper wallet for a lesser-used currency that doesn’t have an address generator website, there is still a way to achieve this.
What every alt-currency does have is a variation of the Bitcoin-Qt wallet application.
Goto the ‘Receive’ tab, where your wallet addresses are listed.
Right-click on the address you wish to save, then copy the address to the clipboard.
Click the ‘Help’ menu and select ‘Debug’.
In the ‘Console’ tab, enter “dumpprivkey” and paste in the wallet address.
The console will then display the private key of that wallet.
You then have the public and private keys of the wallet. You can print these ‘as is’, or you can opt to generate QR codes to print.
However, the wallet details will still exist in your computer. The only way to remove them it is to open your file explorer in the ‘C:\Users\[YourUsername]\AppData\Roaming\[Wallet App Name]\’ folder and delete the ‘wallet.dat’ file.
NOTE: this will remove all addresses held in the software wallet, and you should make sure that there are no funds remaining in the other addresses you will be deleting.
Now you should be the proud owner of an unhackable paper wallet for your digital currency. If a paper wallet is not for you, however, you could use your own mind with a brain wallet."
