Correct me if I'm wrong.

Current market cap is roughly $900 x 12m coins = $10.8bn

To go to $10,000/BTC market cap (with current coin count) would have to be $10,000 x 12m = $120bn.

So to go to those levels we need an extra $109bn invested... suddenly wall street's 'hundreds of millions' doesn't seem so great, not even pushing us to $1000?

I must be making a mistake in the maths, please point it out.
