No, trust wallet isn't fine, quite a lot of people thought the same of Atomic wallet, but look what happened and how so many of their users lost their assets without the wallet even given any specific reason why it happened. Trust wallet may be good for hodling altcoins but it should not be used for hodling Bitcoins, because there are so many alternatives that are better by a country mile, so why risk your Bitcoin by using a close source wallet that is owned by a shady exchange (Binance).
