First of all, happy birthday to you.You did a great job on your birthday because you put food in the mouths of orphans and brought smiles to their faces. I don't know how much you earn, but whatever you earn, feeding orphans with your earnings is probably one of the best times of your life. Just like you gave food to orphans with your earned bitcoins, I also donated money to few and poor beggars in our country with my earned bitcoins.It was only possible to earn my bitcoins.
I am not too interested in you introducing Bitcoin to these orphans because they are underaged and might not have the financial resources to invest in Bitcoin.
An orphanage home does not have only small kids, there are also teenagers of 16-19(yrs). I could only get the picture of these kids because it was more of video than snapping. I heard that on Saturdays is always there skill acquisation day, i.e they have experts that comes from outside to teach these children different skills based on their area of interest.
I think 16 to 19 year old teenagers have enough knowledge to understand or learn Bitcoin.It's not that they don't have talent when they say they're orphans.Talent exists in everyone, whether it is less or more.I believe that if you make teenagers 16 to 19 years old understand bitcoin well then they can definitely learn and remove their poverty in future.
