Then you must have used the coin mixing option, and that comes at a price, which is not cheap if you look at what @Charles-Tim wrote in his post. Therefore, I am sure that your problem with the gradual disappearance of coins has nothing to do with security, but with the fact that you were not aware of the costs you paid for using some functions of the wallet.


I hope you know the saying “not your keys, not your coins”, and the difference between what you use now (custodial wallet) and any other crypto wallet that gives you complete control over private keys.
