I believe you may have a fundamental misunderstanding of how markets work. If you had 37.3k bitcoins to sell, the price would not go to $90. The bid depth is what is on show in the order book. Its not what's available overall.

I also like how you say "when mining becomes impossible". How, exactly, does that work? You do realise that difficulty can go down as well as up?
