I’m trying to download electrum to store my Bitcoin as I no longer want to use blockchain anymore since it’s not well secured. I don’t know if I should check on App Store and download electrum from there or I search on goggle?
You are using Iphone, if true, condolences to you, Electrum still does not have a version for Iphone users. I'm also on an iPhone, and I've been waiting for the iOS version for a long time, but I'm still disappointed about it. If you want to use Electrum, you should use it on a computer or phone with an Android operating system.
