When I started to learn about bitcoin and buying some, they were around 200-300$ before the first big spike.  Now I just trade altcoins and hold bitcoin.

Well if you want to know if the Earth is round or flat, the easiest way would be to attach a phone to a balloon and have it record all the way.  But lets say you don't want to believe your phone and the government controlled your phone and added fake footage.  The option for you would be to become an astronaut and go to space.  After escaping orbit, look at Earth.  Is it round or flat?
