BTC has great technology behind it but the software and protocol empower it is not owned by the currency of BTC. With buying BTC you buying nothin but a ponzi scheme. Almost everybody buys it because they expect more people follow that path so price will increase and they will sell at higher prices. BTC is biggest ponzi scheme in history. However that doesn't mean you should short it you can bet on it to continue longer. But end is coming very soon. Do not be greedy.
It will be quick and painless if you listen me.
