Answer to your first question above is yes. Yes, I trust Trust Wallet to continue using it. I first used TW in 2021 and the ease of navigation on the app got me hooked on it. Ever since then, I kept a close tab on it. For those complaining of it being a close source or of hacks, they ought to know that the responsibility of protecting our tokens/coins lies with us. Apps are just apps, not humans. If we don't keep them safe and secured, they will get tampered with and their security breached. It doesn't matter how hack proof we think they're.

Yes, I do have other crypto wallets I use; ranging from Metamask to TokenpPocket, SafePal, just to mention but three.

To the last question, nope. I don't need a hardware wallet at the moment. Maybe when I gather something substantial I can think in that direction.
