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.
Yeah, you have point, person with disabilities have limited sources of work. I agree with this, cryptocurrencies may help disabilities people to earn money, we all know that cryptocurrencies can convert into money. and this thing help them as their income. Government benefits is not enough for them to help their love ones.
