I heard a couple of times that parents buying whole Bitcoin, whole Etherium etc. for their kids. That`s really cute and honestly I think that is good idea. But now with this coin that will be much easier. Definitly original, great idea and I wish you luck for this project.
Bitcoin/Ethereum is too advanced for a kid to fully understand, therefore Pigzbe is a much better token because of the adjusted learning experience to start learning about both cryptocurrency and general economic concepts.
