I've read an article discussing how cryptocurrencies potentially will help those in third world countries. In short cryptocurrencies will enable those who live in developing countries to have access and to join the global economy that might help them with a source of income.
So I personally believe that cryptocurrencies/blockchain will unite and bring humanity together.
From my own experience of living in a farm in a developing country, we worked in a rice field and 1 hectare (10,000 m2) of rice field will give around 5 tons of rice over the course of 9 months, that would be approximately $2300 USD before taxes and expenses for 9 months. Some people could have earned that amount of money in less than a week on Steemit.
Further more blockchain and cryptocurrencies can aid these people to deal with hyperinflation, poverty, lack of jobs, poor infrastructure, and poor access to global markets that happen in those countries.
Thanks for sharing your thoughts with me. I appreciate it a lot.
