You buy bitcoins anonymously in cash and send them to your Electrum wallet.

Examples of online wallets: Breadwallet (BRD), Mycelium, Electrum, Out of Egypt.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.

If you have a need to buy or sell BCC, Microbit Exchange has supported BCC/CNY and BCC/BTC pairs.

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. If you use electrum personal servers, Electrum wallet users can connect locally to their own private servers, enjoying the convenience of Electrum without any trade-offs.

According to GitHub, Bitcoin Desktop Wallet client Electrum has released a 4.0 beta version, adding several important updates that support lightning networks. Electrum primarily adds features such as PSBT (partially signed Bitcoin transactions), Lightning Network, watchtowers (暸 watchtowers), and Submarine Swaps (subliminal switching).

The new version of the wallet will also include undersea switching, which allows BTC to pass from the Bitcoin blockchain to the payment channel network LN. For this novelty, Electrum is based on Boltz technology. Electrum will charge a commission for this service.

By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties. And unfortunately, many public Electrum servers are run by individuals or groups of blockchain analytics companies or worse. Therefore, if you are using an Electrum wallet, it is generally recommended that you run your own Electrum server and then connect the wallet to that server.

Popular wallet developer Electrum has released an emergency patch for a key vulnerability in its Bitcoin wallet. The vulnerability allows any website hosting electrum wallets to potentially steal a user's cryptocurrency. A vulnerability means that the password is exposed to the JSONRPC interface, implying that the hacker has full control over the wallet. The first patch failed to fix the problem, forcing Electrum to release a second update on Sunday night.
