I use many walled and trust is one of them. But since trust wallet is owned by binance company and binance is centralized, I would count trust wallet as centralized wallet. That's why trust wallet can't be good for long term saving and I prefer decentralized wallets. In the other hand, I can't recommended binance savings because even if they are honest with users, they are centralized and this can't be good. Also don't forget the rule saying never keep your funds on exchanges for long or mid-term unless for trading purpose.
