I've also heard before about errors in sending tokens, due to carelessness or fate that they belonged to someone else. The development that has been carried out has reached a perfect stage, in my opinion the error is not because the wallet provided is difficult to understand or the security is not strong, it's just that the user is too careless in sending. In using the address in the wallet, we have to check two to three times, even though the address is copied and pasted, but to make sure everything is copied correctly, do a check before confirming the delivery.
