No. Imagine this. You have some large percentage of the world's bitcoins, acquired through mining. You are keeping them because they are appreciating. A larger percentage are in free circulation. They have to be, because liquidity is required to generate a successful market. Absolute hoarders of bitcoin would fuck themselves over.
Me, I borrow as many bitcoins as possible from whoever will lend them, and lend they will, because of their halfwit belief in the infallibility of bitcoin. This is my short. I can pay for this borrowing because I have actual money.
Because I'm well connected in this real world of actual money, and actual morons, and not just your cryptocurrency imaginationland, I can make real world dollar trades en masse very very quickly. This is what I do.
I sell all the bitcoins I borrowed as quickly as possible, flooding the market and causing an enormous crash. Confidence collapses and causes a chain reaction of selling. With the price in the toilet by a much bigger factor than I could have achieved on my own, I buy the same amount for next to nothing. That I can do this effectively is key. I give these dirt cheap purchases back to whoever I borrowed the other ones from, settling my loan. Short complete, I am loaded. You are having a terrible time.
Then I go & do it all again until you are broke.
Under the right conditions I could do this with any commodity and I could certainly do it with bitcoin. There's nothing special about it in this context.
