To be honest, I actually feel that it might help but not much. I do not think that kid will go to Google and search for "Bitcoin" just because they saw it on their toys. I say it might help because maybe one day when the kid grow up or just started using Google, they might search for "Bitcoin". Even then, we cannot be sure that they will use Bitcoin and support it.

If I were to create a toy for kid relating to Bitcoin, I would create a game similar to monopoly with "Bitcoin" as the money. .

And maybe the "Jail" will be something like "Hacked". Buying a "property" will be like buying a "site". :p.
