-    Cílem jsou začátečníci, kteří nerozumí technickým částem kryptoměn. Pomocí
-    hravých analogií a příkladů si naživo vyzkoušíme třeba to, jak funguje
-    hashování nebo jak probíhá Proof of work na Bitcoinu. Díky vtipným
-    přirovnáním si budete moci představit ty technické a abstraktní věci, které
-    si o kryptu všichni čtete.
