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.
If his/her disability is not in the hands and in the eyes that he/she will use to earn bitcoin why not? Bitcoin is for everyone with or without disability. As long as they have money to invest, talent, skills patient and hardwork bitcoin is also for them. I believe that people with disabilities have more opportunity to be successful in the field of cryptocurrency because they have more time to focus on bitcoin compared to people without disability that they have lots of other activities (aside from bitcoin) in thier life.
This is correct as long the disability wont be on the limbs and eyes then crypto money making opportunity would really be possible to those persons who do have disabilities and i agree on the thing you do said that
bitcoin is for everyone as long you do have the skills,knowledge or having any funds to invest (not necessarily) which you can really take advantage if you do know on what you are doing.
