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.
ERC-20 Wallet should always been use under metamask so you won't need to open your Private Key every time you do a trade to exchange like ED FD and etc.
When you are registering to an exchange platform don't use similar password you use on social medias also always active 2FA if they have.
Always save the key of every account you have to a safe place.
