There are very few people who holds an enormous amount of bitcoins. Could it happen, if someone from them decide to share a percentage of their bitcoins to all other wallets that holds only a little amount to give all poor wallet-owners power at a specified time in the future when there's an urgent need for all of us (global financial breakdown or something similar)?
I think this dream will never happen, Because all people that invest their money in bitcoin only intended to get more money, so I think no one will ever donate bitcoin to those people who they don't know. Unless of course they are victims of typhoons or something. As of the moment, I don't know any reason for people who have a large amount of bitcoin to share their bitcoin to others.
