-The Electrum wallet can only store Bitcoins. It does not support other cryptocurrencies, even including Bitcoin forks (like Bitcoin Cash). However, there are now unofficial wallets based on the Electrum code that offer support for such branches of BTC, such as Electron Cash. This wallet is not related in any way to the original Electrum wallet, but uses an almost identical code. Electron allows users to store Bitcoin Cash (BCH) on a wallet. As we said earlier, Electrum is a software wallet. This means that it offers a more secure environment than an online wallet, but less secure than a hardware wallet.
