Electrum only supports Bitcoin.

But there are forked versions of Electrum for other cryptocurrencies. E.g:

Litecoin - https://electrum-ltc.org/
Vertcoin - https://electrum.vertcoin.org/

Is there a reason why they can't just create an electrum for almost every coin?  Electrum is a very good wallet.
