What wallet should we use then? I haven't been able to try out many wallets (yet). Just looking for a open source non-custodial wallet. I am using trust wallet for some times now, but as we all know it's closed source which is the issue. Apart from that, I don't use CEX/DEX that much often, only when I need to cash out or something like that.

There are many open source wallets but many of them doesn't support that much of cryptocurrency.
