Planet Daily News Electrum is a world-renowned Bitcoin light wallet with a long history of supporting multi-signatures and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign wallet for Bitcoin or even USDT (Omni).

This "update tip" is very confusing for the user, and if you follow the prompt to download the so-called new version of Electrum, you may get a trick.
