Bitcoin went up more than 10x last year so it would be nice if my few hundred € would be worth a few thousand € in a year, and it's not so much money that if I'd lose it, I'd be seriously distressed. (The past week the Bitcoin fell quite a bit because different countries have announced they want to regulate cryptocoins more strictly, so right now I'm at a € 150 loss).

How accurate are those algorithms? I have come across the concept that there are complicated systems and complex systems. In a complicated system, the algorithms are very big and (would you believe?) complicated, but a big enough computer with an i999‑Core processor can accurately model it. A complex system remains unpredictable irrespective of the amount of effort used to predict its behaviour; indeed attempts to monitor its behaviour in real life can alter that behaviour unpredictably.
