You should go for the wallet or exchange site that is suit on you. Trustwallet maybe secured, and trusted by many. But I'm already feeling at home to binance exchange platform.Excellent, as long as you have no need for such Trustwallet application, there is no need to add more charges to your phone. I have also read the review of this crypto wallet and came to the same result, it is totally legitimate and secure. My interest is based on the future possibilities of using it.
