A fair coin is tossed. In the first round, you bet on 1$. If it turns out head, then you bet on 1$ for the next round, if it turns out tail, then next round you double your previous bet.

To let you see what’s really going on, I will show you an example of 10 rounds.
Result of some simulations:
Can you count how many heart attacks you can expect?
