Wake up people already. Bubble can't last much longer, it's game over. You can sell at $500 and get any value out of it, or wait until it goes to zero. Ask yourself, would you rather own 500 dollars (backed by US military and economy) or one Bitcoin (backed by nothing but speculation and held by obscure early miners and adopters). It's so obvious but people always become blind during the mania. If cryptocurrency was ever to live, it wouldn't be bitcoin. Nations can create their own cryptocurrencies, and then your "algorithm agenda" goes down the toilet. Algorithm is basically useless, since it can easily be recreated. Price of bitcoin is nothing but speculative bubble with no fundamentals.
