In my opinion, trust wallet is more secure than Binance and Kucoin because they can hack it at any time and you can lose your coin in it, but if you get wallet, no one can hack it unless you share your private key with someone who has access to it. You can get more details about trust wallet in Google just try and get more ideas on it but some will give you another objection but that is the places I save mind and is still there currently and nothing will happen to it except someone got my private key if you open trust wallet simply find a better place and kept your private keys that no one can see don't trust anyone since scammers are all over the internet now.

You can see why many people don't like saving their coins in Binance and Kucoin because they are just for exchange and you can't be confident that your coin is safe there because you don't have control over it. However, if you have your own wallet, you will have full control over it and can save your funds without worry, It is also more secure than centralized exchange.
