Heelo everyone, I have decide to take my crypto experience to the next level by taking advice of getting a hardware wallet more serious when I can afford one, since I've start making over $1000 and holding assets that's worth more I decide to take this road for my own good.
I have few questions still, I want to know if connecting software wallet to your hardware wallet gives it the security as intended? If I start using software wallet on my hardware wallet does it add more to it's security? Or it's a bad idea?

What other things I need to look out for using my keynote hardware wallet?
As for the firmware update, I have two options, one through SD card and the second through USB connection, which one do you think is better and safer upgrade way?
Is there any Keystone user on here? What's your user experience so far? Mine is Keystone 3 pro
