As I pointed out here on another
thread, another different between gold and bitcoin, is that the later has predicted supply for a given time.
One of the examples to demonstrate the appeared insanity is
Dogecoin - a cryptocurrency that stated as a joke.. but now it's market worth hundreds of millions of dollars.
That, of course, won't change the fact the the Bitcoin might still rise, so the question of weather to buy or not to buy is different question than the question of it's real value.
