January 19 (Xinhua) -- 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-signature wallet for Bitcoin or even USDT (Omni), according to the Slow Fog Security team.
