Well I think Bitcoin won't be a big help for a kid to learn to save money. Bitcoin is not a factor. A factor to kid's saving money is his control to the money. He should be wise enough on how to use the money properly. Use it for good purposes not on luxuries or desires.
I think that bitcoin would help kids about saving. They should know at early age that saving is necessary in one's life. It is an assurance and a platform to preparation. Through bitcoin they will be guided to earn and to save at the same time. They would have big hope for their future.
