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!
This is what I've been looking for as an answer. Yes bitcoin is a way of help but then, we are the ones who will work on it. Bitcoin is just a tool, but we are the navigators to help those children. If will we organize a project that will benefit poor children in underdeveloped countries, then it would make bitcoin more popular because the people who are involved in it have good advocacy not thinking for themselves alone.
