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
But of course, you can give it to anyone in your family that you can trust, because these coins are considered investment someone has to take over it in case something unexpected happen, you can do a will for it and entrusted it to all your inheritors there are so many instances that coins are lost because there are no inheritors..
