Make sure to check the website that you are logging on if you are using an online wallet. There are a lot of phishing site. Try to book mark the website. The best way to protect your crypto is to use a hardware wallet, so that your public key is protected.
agree with you, maybe in the wallet hardware will be safer and more awake. if the online wallet is more careful because it can be read by others and may be exposed to fraud, all of that can happen because of increasingly sophisticated technological tools that are more careful when entering keys. if you don't understand it, you have to ask people who understand better and of course that person is reliable and trustworthy. I'm also new here so I don't really understand and that is in my opinion and according to my knowledge.
