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.
Yes, saving is important if kids can learn this at a young age they would save more in their life time and they will see their profit from it. They will also gain some money from bitcoin by saving.
This will help these kids later on when they are old. They can get the money on their wallets.
