We cannot control if our wallet is being hacked. I have already experienced this when I noticed that my wallet has ETH deposited in there and that one of my token was being withdrawn. What I did in order to save the rest of my tokens, I withdrawn the ETH in order for the hacker not to withdrawn the rest of the tokens there.Then in a hurry I transferred my tokens to another wallet. So in my opinion it is better to check regularly our wallet because we cannot be sure if there are still tokens in their. In this crypto business there is not security of the wallets that we have because there are lots of strategy that hackers offer to. So maybe in order to save our holds tokens maybe there is a need to regular update on the wallets.
