<br />
== Task ==<br />
<br />
In the '''Overview''' panel, The '''From''' field has: Satoshi 2 sending 50 Bitcoins. And in the '''To''' field Hal received his Bitcoins and Satoshi 2 received some Bitcoins back. <br />
<br />
<br />
How much "change" did Satoshi2 received in this transaction?<br />
<br />
<br />
'''Key Insight:'''<br />
<br />
<br />
* Bitcoin addresses behave like "bills" or "checks." <br />
<br />
* When sending Bitcoin, the full amount in the address must be transferred, and the "change" is sent back to the sender. <br />
<br />
* At the beginning, Bitcoin addresses contained amounts in multiples of '''50 BTC''' because they were obtained from mining rewards.</div>BeginnersGuide>Marin
