<p>To make it harder to relate your different transactions, you should use a different receiving address for each transaction. <i>Electrum</i> automatically generates new addresses for you to use.</p>
<p><i>Electrum</i> uses <i>mBTC</i> as the default base unit. 1 mBTC = 0.001 BTC. To change the base unit, choose <span class="menuchoice"> **Tools** ▸ **Preferences**</span>.</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.
