I would not believe bitcoin would end poverty. In fact bitcoin is use in illegal transactions like drugs and human trafficking. How could they end poverty? Unless the big whales would share their bitcoins. 
Nope, do keep in mind that all currencies are probably used in illegal transactions, yes it may be used as a payment for some illegal doings, but not all of it, and Bitcoin wasn't created to be a currency for illegal transactions.
Nope, Bitcoin is limited and doesn't have the capability to end world poverty. Maybe for some people, but no all.
