For me bitcoin cant end world poverty because first of all not all of the people in different countries knows about bitcoin. Some doesnt have enough materials to start bitcoin. Some countries didnt approve to bitcoin and even if a country allows bitcoin it will still depend on the people. Wether they are interested or not, if they believe in it or not because the people will make and do the job and bitcoin is just an instrument. In the end it will still depends on the people if they will embrace it or not.
