In basic terms, each bitcoin is currently worth about $1050, so 16 million bitcoins are worth about $17 billion. If you add $10 billion to that, then each bitcoin would be worth about $1690.
Im still confused on how did you compute this one? Very well basing on the current supply of bitcoin but basing on those bitcoin whose lost forever 16 million bitcoin wont be the exact number i think the price of bitcoin will sharply go above that certain price point that you mentioned.
