Thank you @ivanli for your video here on steemit.com (Blockchain, Hyperinflation and Corruption) and on youtube (Bitcoin and Blockchain ending world poverty?) I think blockchain and such technology could really help in countries where it is hard to buy just an egg or one day's electricity. Some wallets have been developed that can handle such small transactions with little to no fees. If wallets and currency can be contained on any device including flip phones for example and can be used across country lines this may help millions of people.
I also saw a similar video on youtube:
