@amrulshare. That is why I said learn how to use the command line and know how to store your grins properly. Many people did not try when Monero was under $0.50, which might also have caused them to avoid buying it and miss an opportunity.
someone assumed , this protocol has a problem within cold storage in hardware wallets are tricky to implement. this means developing a hardware wallet like trezor or ledger is not possible ?
No way this is true. I don't know about Trezor but I'm a Ledger Nano S owner. Ledger offers 3 options of connecting to your wallet,
- Through their own app, Ledger Live (obviously)
- Through web apps, like MetaMask or MyEtherWallet
- Through 3rd party local software, like ARK's wallet
I believe ARK's case is the best example. Ledger doesn't offer access to ARK coins from within their own platform (Ledger Live) like they do with most (all?) other of their coins.
Instead you have install the official ARK wallet and connect your hardware device, then your wallet(s) are automatically recognised and shown in the list.
Even if Ledger can't integrate GRIN in their platform, someone could create the Windows wallet so that it reads from hardware devices and accepts signatures from them.
The only real problem I can think of is if GRIN would require a lot of memory from the hardware wallet, is that what you meant with your post?
But even in that case, the newer devices have larger memory so it should be supported at least in these newer devices.
