Answer:
I break down buildings, I crumble mountains but you can't see me. What am I?
I am black when you buy me red when you use me when I turn white you know itβs time to throw me away.
If you drop me I'm sure to crack. But give me a smile and I'll always smile back.
I go around and in the house but never touches the house
I am two-faced but bear only one. I have no legs but travel widely. Men spill much blood over me. Kings leave their imprint on me. I have greatest power when given away yet lust for me keeps me locked away.
