WTF? How come bitcoin is still unknown to the common people? Start ups after start ups have managed to raise millions and millions in funding but more than 50% of the common people doesnt know about it?
What do you think is lacking? What are bitcoin's shortcomings?
Why not try this experiment at home.
Ask your mom, ask your dad, your aunt and uncle, your wife, your brother, your sister, your in laws ---see how many know about Bitcoin.
