<p>To make it harder to relate your different transactions, you should use a different receiving address for each transaction. <span class="application">Electrum</span> automatically generates new addresses for you to use.</p>
<p><span class="application">Electrum</span> uses <em>mBTC</em> as the default base unit. 1 mBTC = 0.001 BTC. To change the base unit, choose <span class="menuchoice"> <span class="guimenu">Tools</span> ▸ <span class="guimenuitem">Preferences</span></span>.</p>
<p>Do not blindly trust the bitcoin balance that <span class="application">Electrum</span> displays as <em>unconfirmed</em>. Wait for transactions to be confirmed.</p>
Turn on the [[Electrum Bitcoin Wallet|persistent_storage/configure#electrum]] feature of the Persistent Storage to store your bitcoin wallet and preferences across separate working sessions.
