Hey Chris,

thanks for sharing the article. I think I spotted a minor logical error in it tho.

> This is because on average, you will gain $1 with every coinflip. For those interested in the maths, you have a 50% chance of winning $2, and a 50% chance of losing $1. 50% * (+2) + 50% * (-1) = +$1.

Isn’t it an average gain of $ 50ct per coin flip? That way the calculation would be correct aswell.

Yeah, I'm also pretty confident it's an average of +50 cents per flip.

E.g. if you get 50 heads and 50 tails in 100 flips, that's +$50, which maps to 50 cents per flip.

Good pick up!
