         <source>Mining with your computer helps strengthen the Monero network. The more that people mine, the harder it is for the network to be attacked, and every little bit helps.&lt;br&gt; &lt;br&gt;Mining also gives you a small chance to earn some Monero. Your computer will create hashes looking for block solutions. If you find a block, you will get the associated reward. Good luck!</source>
         <translation type="unfinished">Kopanie z udziałem twojego komputera wzmacnia sieć Monero. Im więcej osób kopie tym trudniej zaatakować sieć, a każdy najmniejszy wkład jest pomocny. Dodatkowo kopanie daje ci małą szansę na zarobienie Monero. Twój komputer utworzy hashe/sumy kontrolne aby znaleźć rozwiązanie dla bloku. Jeżeli znajdziesz rozwiązanie wtedy otrzymasz swój udział w postaci zapłaty w Monero. Powodzenia!</translation>
