Quantum mechanics tells us that things are random. Even if you could chart every particle in the universe, you could not predict everything. Although, you can find likely outcomes.
Haha I was waiting for someone to bring up quantum mechanics. I feel like that's the only legitimate argument you can make against what I said. I don't understand enough about quantum mechanics to really discuss this, but from what I've heard from people who actually study it and know a decent amount about it (nobody knows "a lot" about quantum mechanics) all of the things about randomness are still pretty theoretical or just not well understood.
It's a very interesting subject, but regardless it doesn't conflict with my point that bitcoin prices are NOT random.
You should check out "Through the Wormhole", they spend a lot of time on the subject. Basically if you shoot a electron through a solid flat surface it would leave more then one hole. Unless you were observing it. May as well be magic, to our generation at least. We might just be living inside the matrix, that's just a glitch in the program..
