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
There are two ways how to protect your private key from hackers.
Never go online with your private key - so, create some paper wallet.
Or buy hardware wallet, this wallet will safe your private key outside the computer - hackers cant access it!
I prefer with the hardware wallet, and I think it's the best wallet that we can use. Besides that, we don't have to afraid from the attacker, as long as we can keep the hardware wallet safe and no one knows where the hardware wallet, then we are very safe. We can use the safety box in our banks too to keep that the hardware wallet and only we that will keep the keys of the safety box.
