Electrums was originally created in 2011 compared to other software wallets, and one of the biggest advantages is that its server indexes the blockchain instead of downloading the entire Bitcoin blockchain, which makes downloads faster and less downloadable. Electrum also provides many protections for your Bitcoin, including cold storage, allowing you to store Bitcoin offline, and restoring the "seeds" of Bitcoin in the event of a failure (hackers, computer corruption, etc.)

According to Reddit user u/normal_rc, electrum's wallet was hacked and nearly 250 bitcoins (243.6 BTCs, nearly $1 million) were maliciously stolen, according to coinelegraph. Electrum then confirmed that the attack included creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is a persistent phishing attack on Electrum users" and warned users not to download Electrum from any source other than the official website.
Electrum Wallet is one of the most popular Bitcoin wallets and has been around for several years. However, Electrum wallet users often rely on electrum servers, which presents some security and privacy trade-offs.
