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
Indeed and never be fall on the sugar coated words of the others because this is one of the main reason why others gave their key on the other person because they are deceive by the fake promises of the other like they gonna transfer some token in you account etc. that is why they give their key on it. So maybe the best way to rid this kind of act is to be smart so that you will have no regret in the end.
