I am new one in this market place, so it is important to know the safety issues of the wallet. Please someone help to understand the issues of safety of the market.
Yes of course it is important to make sure your wallet is safe. The safety of your wallet depends on what wallet you are using now.
If you want to store ETH or erc20 tokens, you may use metamask for free, or hardwallet if you can afford to buy it from legit vendor.
