Suddenly chatting with a friend today. How do blind people use mobile payment? We don’t know the daily life of blind people. Blind people pay with paper money, but will digital currencies replace paper money in the future? (However, there is no certain mark on the U.S. bills, and the blind cannot touch the face value of the legal currency)


There are also some elderly and children who do not have mobile phones. Children can take care of them and learn cryptocurrency with their families. However, many elderly people have no children and lack the ability to accept new things. With the popularity of Bitcoin, will they continue to use paper money in the future?


In fact, for blind people, no one pays too much attention to their lives. Because there are no blind friends around, they don't think so much. If some technology is developed, it is very expensive consumption.
   With the increasing popularity of Bitcoin, what do you think will happen to blind and childless elderly people?
