1. I don't really trust Trustwallet. But I still use it for transactions and Trustwallet is simple and easy to use.

2. Yes of course I use several other wallets. I love the experience of using multiple wallets. Currently I also use Metamask and Coinbase to store my assets.

3. I think it's very important. I believe in the saying "not your keys not your coins". Of course Trustwallet gives us the private key to our account. But I think that Trustwallet is not as safe as hardware wallets. I currently store all my crypto assets in a hardware wallet. And only use a small portion in the digital wallet.
