An illustration could be McDonald's offering of a burger for $1, where you'd prefer burger and McDonald's would prefer $1. If you give them $1 and McDonald's give you the burger, both of you would be better off.
The underlying assumption is that your utility of the burger is greater than $1. Which is true because MacDonald is very, very efficient at making burgers (compared to you).
With bitcoin, it's a speculative trade. Everybody is "equally" good at making a coin. So the trade is happening purely due to an expectation of future utility, which may or may not come.
