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.
I feel we are looking at the whole picture too much and forgetting the fact that we are referring to disabled people here. First and foremost, the fact that government is helping them to sustain their needs is because they really find it hard to survive, and you think they are going to be in their right state of mind to understand everything you will be telling them about cryptocurrency? Sure, it may depend on their disability, but most disability that I know of, simply limit those people from doing certain things. Blind, deaf, dumb, crippled, name them, find it hard to even cope psychologically based on their situation and you think this would help?
