I don't want to hold hardware wallet like ledger nano wallet ..
If I'm going to guess, you don't want a hardware wallet because you want to use your wallet on your mobile phone. If that's the case, then go for the Ledger Nano X it has Bluetooth connectivity.

I agree with the point and about Ledger being a very well-trusted company, but if the op doesn't want a hardware wallet, wouldn't you agree that Electrum is totally fine? It's secure, it's non-custodial, and it's convenient. Is there a good argument against using Electrum and opting for a hardware wallet like Ledger instead? To me it seems to be more about personal preference and a sense of safety, but that Electrum is secure enough not to worry about needing even more security.
