Trust Wallet should be treated like hot wallet i.e. only store amount that you can afford to lose, probably less than $500. If you have more than that, it's better to store it in cold storage or hardware wallet in order to be safe.
You might have no problem using Trust Wallet and you have use it for few years, but we don't know what will happen in the future. Trust Wallet is owned by Binance, so if Binance going bankrupt, that's when we will see the true face of Trust Wallet.
This is what I always do with trust wallet, I used it for my gambling activities only and I have never store more than $200 in my trust wallet (mostly for tron). I have been using it for the last 2 years, luckily I have not experienced any issue. No doubt that I have to agree with your statement, we should always use such a wallet wisely.
