hi thank you for the complete information just what i really needed as a beginner, just wanna ask if all of the wallets mentioned above are applicable to any country? thank you
A wallet should work everywhere as this is the whole point from bitcoin, an exchange however could have some restrictions where Its either illegal to use it or an ID verification is needed.
Hi!
I´m totally new to this and just installed Electrum. Afterwards I got a little concerned about the two-factor authentication that I did not choose.
It´s supposed to protect us from malware and now I only have the standard wallet.
Tried to reinstall it but didn´t succeed with that one..
Should I be concerned or just go with the standard wallet as a beginner?

If you are holding large amounts of bitcoin, just go with a hardware wallet otherwise a desktop (standard one) is just fine even without the 2FA. If you still want to setup one, go to File -> New/Restore (CTRL+N is the shortcut) and follow the instructions[1].
