Hello
I have 128gb ssd. I installed portable ubuntu on this ssd. When I need to use my wallet, I connect it via usb and boot ubuntu instead of windows. I installed Metamask on chrome here. Only metamask operations and ntf etc. I use for. When the processes are finished, I close the ubuntu and remove the ssd from the usb and restart windows.
Will this system be as secure as other hardware wallets?
Thank you so much!
