Very helpful advice but I had some things to know if you don't mind then you can tell me. Can the Electrum be a good wallet for mobile users for a long time? What kind of security practices do you need to practice if you want to save money in Electrum from any other exchange, What kind of precaution should be taken in case the mobile is often lost or damaged due to mobile usage?
Always keep a copy of your seed phrase on a paper stored in a safe place like a vault, that alone can restore your funds in case of lost/broken device.
Do not save it in the same device, online or cloud storage, or anything that's connected to the internet because of the reason above.
As per security measure, it's a mobile device so it's not recommended for hodling Bitcoins for a long time.
I wouldn't recommend any mobile wallet for that purpose at all.
It's off-topic BTW, next time, please create your own thread if it's not related to the topic.
