1- Metamask supports coins of a certain standard (erc-20). If a user has coins of other standards in a hidden wallet (for example, bitcoin), then he will not be able to access this. How to be in this situation?
I have no idea about Metamask specifically as I have never used it, but each hidden wallet can store any number of different coins. You just need a compatible wallet in order to access each one.
In my post, there is a link to a video about this from trezor. I guess it says metamask supports hidden wallets, so it does. Regardless of the lack of ideas and experience of use.
2- In what other applications can restore a hidden wallet? Is this possible in electrum? I already know about trezor and metamask (information from the official site). If trezor suite stops functioning (don't even ask for what reason).
Yes, Electrum supports passphrases. Most good wallets do.
You will never run in to a problem of not having software which can recover hidden wallets.I would also just add that Trezor now support
government surveillance and control, and so is a very poor choice of hardware wallet.
What kind of wallets do you include in
most good wallets?
Surely there won't be a problem? Devices from trezor support coins of various formats, which require completely different applications to store. My question was that by sending a coin to a hidden wallet (during long-term storage), will it not turn out that access to these coins will be lost? Due to the fact that trezor suit ceased to exist, and other applications that allow you to restore access to the wallet simply didn't exist in nature (that is, there were such wallets, but initially didn't support hidden wallets).
What
government surveillance and control are you talking about? If now trezor hardware wallet is considered a very bad choice, then it’s not even clear which wallet is considered a good one.
Actually, this is not surprising. Governments could not ignore the major HW device manufacturers. Now they will take on less
fish?
