This is a common thing happens in different countries where the government mandatory give assistance to there citizens with disability, and the sad truth is that the assistance from government is not enough.
This is the perfect time to introduce bitcoin to persons with disability by doing this they don't need to rely only on government assistance, because they are now started to earn there own money to support their needs.
I would say that bitcoin is one of the greatest things that we can only apply to those who are disabled, but if we will speak about cryptocurrency involvement in general because bitcoin is not for everybody.
