Securing a bitcoin wallet is very important, because that's where all the bitcoin wealth is stored.
It's not all about Bitcoin but all of your assets either Bitcoin or Altcoins.
When securing a bitcoin wallet besides using a double security key, it must also be remembered and stored in a hidden place, because don't forget. Forgot to mean disaster, because we will lose everything.
And also you have to know where do you hide your key, it's silly to see that people forget about where did they hide and it becomes a mystery as the time goes.
Of course it is important! If you choose a wallet that doesn't have good security, there is a high chance that you can lose your tokens if you do not consider the security of the wallet. Always find a wallet that have security to protect your tokens.
Either the wallet's security is bad or you are clueless about how to secure your assets.
