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!
Exactly, bitcoin is only going to be a tool, and if the past experiences with other tools are any reference, I think bitcoin has the potential to help some people but it is not going to make a huge difference because at the end if the world is in the state it is, it is because people want it to be that way, so I do not expect to see any kind of radical change.
Definitely, bitcoin is a big help to children specially to undevelop countries only if they're are going to take advantage of it's usage. But as they say that if you're going to work hard on it there's gonna be a big result awaits you.
