Bitcoin itself is not going to turn to a human to help. You and I are the ones who will create that platform to help from the wealth you must have accrued from being an early adopter of bitcoin.
Do as much as you can in your own little way and if we all keep that going, you'd be surprised at the number of poor children's life you will be touching. We all have a part to play!
Yes, bitcoin is not enough to help the poor children or the poor countries itself. Bitcoin is not even that stable, I guess the best way to help is to provide free education to them to help develop their lives and also their country.
