With your product people need to use smartphone and they are all connected to internet all the time, plus the cell tower connection.
I don't care really about shitty metamask wallet and how they are handling their supported centralized coins.
With the desktop version that we are developing you can choose to use on iOS, Android, Linux, Mac or Windows.
they still don't need an offline backup if using a software wallet,
Offline backup is always necessary, because this exist seed recovery phrase. Because if the computer or smartphone crash, it is easy to recovery funds with the backup
Or the user could have an actual vault to store valuables and seeds. Or they could have encrypted microSD backups laying around, of their hardware wallet, created offline - by their hardware wallet.
Yes, microSD can be used to store encrypted seed recovery phrase. But, few users know how to do that and is not resistant to water, fire...
So maybe, CryptoPlatz Vault is just no for you guys, but for users that have cryptocurrencies on Trust Wallet, Metamask, Ledger, Trezor, Exodus and want a easy, safe, encrypted and offline device to store the seed recovery phrase.
Thank you for your advise! Help us a lot!
