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.
It will of course depends on how the person is disabled and what he or she can do but I think for most of Disabled People bitcoin is really some kind of saviour in financial sphere, so they can meet their needs.
