That's the best thing you can do is to keep the Bitcoin in wallets that are made dedicated only for Bitcoin like Electrum, Sparrow wallet or the blue Wallet etc and keep the altcoins separately. I also follow a similar practice.
Based on the experiences of other people that I have followed and studied myself through reading habits, it is true that the best practice in storing assets such as Bitcoin is not to put them together in one wallet. Electrum is very popular and has been tested by many users, following in the footsteps of those who have recognized the advantages of Electrum as the best wallet, it is not wrong even though I am not as knowledgeable as they are.
I have never used Sparrow, but I still use Bluewallet for storing BTC which is not in large quantities.
And Unstoppable, I only use it as a wallet to store altcoins.
I will store this command in memory indefinitely.
