I just Wanted to use Electrum as my BTC Wallet, Is its Safe?
It is safe as long as you backup 12 mnemonic seed phrase in a safe place.
Secondly When I was Going to Download It I found these Links?
1. Standalone Executable (signature)
2. Windows Installer (signature)
3. Portable version (signature) (security advice)
4. Note: The QR code scanner is not supported in Windows binaries
From which address Should i DOWNLOAD?
I would go for either Windows Installer or Standalone Executable. I depreciate using Portable version because of security and other problems.
