If you look at TAM only as a game, then yes. You might be right.

TAM is about implenting crypto to the real world, so users who are not in crypto, can play it, by paying let's say with Google Play in-app, and get real $$ for their actions without ever having to touch crypto exchanges.

We take away the "difficulty" factor for regular users who fear new things like crypto.

With the Facebook games, rest assured that you will see TAM explode high up the charts.
