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
Private key is important thing to access our wallet. Better keep it in safe place and never share it to anyone. Many cases peoples wallet accessed and their coin gone because they can not secure their private key. If we want to secure more our wallet, buying hard wallet is good option
