Hello everyone. I was hoping someone could clarify for me why I am getting this message as I'm unsure if it's safe to continue with my electrum download?
Is it normal to have 3 valid signatures?

I have finished the process of verifying electrum using Kleopatra. I used the appropriate file on Kleopatra (downloaded directly from Electrum's official website): ThomasV.asc   

When I click verify on "electrum--4.15-setup.exe.asc" I receive the following message (the top of the message says "All operations completed" with a thick green line) :



Verified ‘electrum-4.1.5-setup.exe’ with ‘electrum-4.1.5-setup.exe.asc’: 3 valid signatures.
