It is sad to think OP that there are such situations. Here among us, there are visually impaired people who are helped by government agencies to get a job. They have their organization of massage therapists. I noticed someone when my mother once took me with her when she availed of their service, that one of them, despite his disability, is a fan of technology, and is the geek type. I saw that he was using a smartphone even though he was completely blind, I just didn't know what to call the software he was using, maybe a screen reader or text-to-speech tool and I admired him. But I just don't know if he also knows about cryptocurrency, it's been a long time, a few years ago.
So today, I searched the internet to see how there are people like this who are interested in Bitcoin and cryptocurrency. I read this story of Michael Staffen, he also had a visual impairment and he was one of the supporters of Bitcoin in 2014, Bitcoin-QT was the wallet he used then and he said he couldn't do anything because he only used a screenreader, he couldn't even access like send/receive a coin, fortunately, he has a sister who is also a Bitcoin enthusiast who helps him. It was also mentioned that he was hired by Coindesk to be a beta tester who will make the wallet usable for those like him, the wallet referred to here is MultiBit, but as far as I know, it was deprecated in 2017. I also found nothing news about him.
Bitcoin 'Needs to be More Accessible for the Visually Impaired'"Most people want to make it accessible, probably including the developers – they just haven't considered it. That's one of the problems around accessibility: It's not that people intentionally exclude others. It's also up to [people with disabilities] to make noise."
