I just bought a Cold Wallet to secure my cryptos, it's a (Bank) smartcard with NFC/Contactless and Contact technologies, supporting 16 Wallets (16 x Private/Public Keys).
So you're saying that you just bought your own cold wallet which was manufactured by your team?
And how does it differ from other hardware wallets e.g. ledger and trezor? Why people will use that wallet instead this HW that was used, trusted, proven and tested by many already.
