+[[!meta title="Exchange bitcoins using Electrum"]]
+
+<span class="application">Electrum</span> is a [[!wikipedia bitcoin]] client that is
+particularly suited to the context of Tails because:
+
+ - Your wallet can be recovered entirely from a passphrase, called
+ *seed*. So you can use your wallet from different devices and avoid
+ losing bitcoins in a backup mistake or computer failure.
+ - Electrum does not download the blockchain. So there is no waiting
+ time when starting.
+ - You can sign transactions from an offline working session.
+
+<div class="caution">
+
+<p>Bitcoin is <a href="https://bitcoin.org/en/faq#is-bitcoin-anonymous">not
+anonymous</a>.</p>
+
+<p>To make it harder to relate your different transactions, you should use
+different receiving addresses for each transaction.</p>

+To learn how to use *Electrum*, read the [documentation on the

+<p>If you loose your <em>seed</em>, then you loose your entire wallet.</p>
+
+<p>That's why we recommend that you activate the [[<span class="guilabel">Bitcoin Client</span>
