Electrum

Electrum is an application that works as a bitcoin wallet. With it, you can easily protect your coins in case you make a mistake when creating backups or your computer crashes. You can restore your wallet with a password that only you know. What's more, when you start Electrum, you don't have to wait; it doesn't have to download the bitcoin blockchain if you're not on a remote server.

With Electrum, you have greater security because the private keys are never sent to the server, and the information sent by the server is SPV-verified.

Moreover, this wallet works beautifully when multiple public servers are available. You can change instantly and use the same wallet on different computers.

Electrum is quick and light. It includes everything you need to use bitcoin daily with confidence.
