You are right guys, that's exactly how it is... i already have trezor wallet but i use the electrum too, for "quick" transactions. i feel confidentially with the electrum, because of the good reviews but if you are not very good protected (i understand it now) everything is vulnerable... im using for mobile samsung galaxy s7 whit android 8.0.0 and i use no custom keyboard. my computer is a simple desktop with windows 10 pro 64bit eng 2016 edition(old)
