Well your wallet is where you keep your coin safe and it always important to protect it
One of the best way is to protect your private key never give it out to any one even if it's your mentor that is very important
This is for new guys like me
Just use hard ware wallet to keep all of your crypto safe.
But if you couldn't afford it then make sure that you would secure it in any flash drive a new one would do to know that it is free from virus or any threat.
