I won't use linux-x86-64_1.7.13_MyCrypto.AppImage because I'll need to install AppImage on my Debian 10.9 OS. From what I read on the internet, AppImage contains many security vulnerabilities.
As for standalone_1.7.13_MyCrypto.zip, I downloaded and unzipped it. You know what, it's for the Mac OS.
Summary: It's rather disappointing there's no open-source wallet for Ethereum, unlike Bitcoin which has Electrum.
